00:00 Coding one that progress? Ok. . Ok. So what's your,
00:37 your problem? Ok, I know about. OK. OK, I've
00:56 this. Uh thank you. You it, I guess. Mhm.
01:47 . Yes you can use another. . Mhm. Sorry. So why
02:16 you sign the data instead of paper ? He said oh yeah you you
02:42 you you should change you not uh again and open again, you know
03:00 uh yes you good. Um let me do my micro going on
03:15 going very, very slippery. Yeah there there OK, so you drop
03:27 me in. That's good. Uh but oh the 25 points.
03:38 That's OK. That's ok. Do like the round out there? I
03:43 the 25. Yeah, that's You're all right. Um they're using
03:52 lightly different version. I want a around here and you know you do
04:06 ever see the, the se like said yesterday just to, you
04:12 lady was looking at the geometry and was saying, oh it's not saying
04:16 and 1225. It just like Yes. And I sent you
04:23 Who, whatever that comment, if says 250 or 2500 you got,
04:32 have an issue with your trace letters it doesn't go at all. Definitely
04:37 . Um, so what, couple of things about a trail?
04:44 don't know. You're recording me. , I'm just building. Ok.
04:47 , Jessica. Are you still She might still be there. I'm
04:51 . Right. What time is One am not quite, uh,
04:56 is 1105, 1105. Ok. right. Um, so with patrol
05:04 notice it takes a little while to up. So what they do,
05:09 software is encrypted that way. If you find it and take it
05:15 you can't do anything with it. you have to have a license file
05:21 you may have noticed in the lower when you logged in the license
05:26 What it does it starts at decryption . So it takes a while to
05:33 and then it comes out. So the first step is to load
05:39 seismic data, it's in set Y . It has uh the seismic data
05:45 has trace headers. Well, first all, it has something called a
05:49 header that will tell you ideally it'll you when the data were required what
06:00 of the world it's from and what most important wine header and trace header
06:08 are and what projection source though. mic is falling, the my mic
06:15 on the ground. Sorry, I need to have better way gonna
06:27 this there we are to see if work uh better. OK. So
06:36 uh so everything is projected on the , OK? In North America we
06:45 NAS 27 and NAS 83 North American system uh 1927 they redid it in
06:54 and from you guys who are gonna in the United States, uh That'll
06:59 you all kinds of headaches because a of the whales are in the 1923
07:03 , in the more modern excise in 19 83 systems. And you gotta
07:09 the projections and so forth. the most important header information are the
07:21 . So the line index and the index and they might be called in
07:28 and cross line. They might be line number CV V number and depending
07:34 you are in the United States, of them are local grids in
07:41 the whole country is on one I think Colombia might be on one
07:47 as well. So that's not uncommon have a grid. So you by
07:52 what the line number and CD P , you know exactly where in the
07:55 where you're at. OK. Uh the US, it's kind of um
08:02 the numbering is arbitrary. So if have three or four overlapping surveys,
08:10 every survey will have a line one one and, and then the for
08:16 . Ok. Then you'll have X Y coordinates. Now patrol started with
08:29 a geologic mapping package. And now wanna think of, I've got 400
08:36 with well cops and I wanna make map and the wells are irregularly
08:43 So each well at a particular well has a XY and Z because the
08:50 are usually a little deviated. So of the mapping and bereal is done
08:58 the xy grid because they started with and only B that waiter, they
09:06 seismic data. So what they use the XS and Ys in the
09:13 OK, or whatever projection system you landmark or, and Kingdom Swede and
09:24 of the others started with 3d seismic the wells later. So they tend
09:30 the line numbers and the brush line are king and then you have the
09:35 with the wells to convert them to line number and well liberty at the
09:42 of the day, you're gonna generate grid and in the row, the
09:46 is done numerically based on all of XS and Ys and we square fit
09:53 Xs and Ys to the grid that to the um line numbering and cross
10:02 number in line and cross line number you won't have is if you have
10:16 traces in the survey. So the , there's two kinds of traces that
10:21 zero. There are traces that an or a processing company kill. And
10:28 believe there's a dead trace that saved this. And then there are traces
10:34 were never recorded and a better way calling those are padded traces. So
10:40 padded traces are outside of the What you need to make a square
10:46 a rectangle. OK. So those been padded traces and depending on where
10:52 are in the world, what the is if you have a cutout
10:56 uh and this is common in North , we have cut out areas where
11:02 Jones doesn't want no shaving geologist on property. And can we image underneath
11:08 ? Yeah, you've gotta cut it unless you have the per from
11:12 right? So the crossing companies see when you give it to the oil
11:18 , they have to cut it So sometimes those are dead traces and
11:22 they're added. So where the complication in just you'll remember this 5,
11:27 years from now, like what the is happening? Nothing rendered properly and
11:32 your, if you're reading the data the dead traces and you want to
11:38 something, export it the same way read because you have a choice.
11:43 wanna order with the dead tra add or do I wanna import just the
11:50 trays or whatever you do be Because if, when you bring it
11:55 the next time he will come out of 24.999 like Lily had the attribute
12:05 you generated. And let us say some Russell might come in as
12:11 And then you can't overlap it on of each other, but always using
12:16 what really annoying. It took me years to figure out that's what was
12:22 on because it's a million Xs and things. So that's kind of unique
12:27 the truck. But OK, we need to worry about the projection system
12:33 we don't have wells for this data in the Karaki Basin. Uh They
12:38 a universal transverse system which is most the world uses. We use it
12:46 me by the act. Um There's modern Southern one you need, there's
12:51 difference and, but for a lot new Zealand public domain data, there's
12:57 new Zealand Protection systems. You need know right now. You can be
13:03 . So don't worry too much about . OK. Did you get
13:08 OK. You got some questions. . All right. Are you trying
13:14 load the data? No. So have to create a new project.
13:19 I think you're open. If I called the new project, I would
13:23 down here and right quick and see it's all you know it now.
13:28 ? Go ahead and create a new . OK? Choose the license.
13:32 , so serious. Feelings to And did you ever get a pass
13:39 ? So, um we actually do alone or I will probably ask for
13:44 new project, you know, the . OK. Yeah, you
13:51 you can go out there. That be fine. And then, uh
13:57 yours popped up. Did you write ? There you go. OK.
14:01 now you're gonna write quick in the thing. So you may input a
14:07 at the top and then in the down here you're gonna go to way
14:12 . It'll say something said Ysegy uh the uh yeah, that's good.
14:27 , and then you gotta find your . We were in the V is
14:33 I couldn't find mine. I'm gonna to the list. Yes,
14:37 Were you on the dish now? you. Ok. So I don't
14:51 you have any. Did you put ? So I did it the right
15:05 is uh initializing every status will show bottom of the lab 821.
15:18 if I have, if we're well of it, I will choose
15:23 point for the next but because we have things like that. No,
15:44 choice is telling me my. But next Tuesday. Ok. And
15:53 know I trying to be a patient like that. So um so thats
16:01 when if you wanna be ok, we can go on that way in
16:14 of me tutorial um um kinda weird where, what do I talk to
17:00 ? No, I don't think that the like, oh, I know
17:23 . Yeah or so but I Ok. Ok. Right. And
17:51 we finish that. Hey, that's close like that. Yeah. Yeah
18:07 , the UTM that I have for 59 6000 on phone to sever let
18:18 try this. I see it. that good? Ok. Oh,
18:57 . Work for you. Ok. are you? And, but maybe
19:56 , that makes sense. OK. was. Yes. So we want
20:24 look at the thousands. OK. we have and so after we authorize
20:46 yeah, the way you look at . So yeah. All right.
21:03 the? Yeah. So it tells to select CRS or to continue spatially
21:14 . OK. So continue spatially unaware stop down here because we don't have
21:40 in the body that Jack that the is you walk. Bye.
22:29 Oh Yeah, you state I know never been OK. OK. That
22:49 help. OK. How does that ? Do you know if we have
23:02 purchase the textbook textbook? Yeah, OK. What? OK. Give
23:17 a project and uh yes on your . Yeah. So do you know
23:44 the, where do you say that data is that the projects, you
23:54 , so they are separate this, have a lot of their project using
23:59 same data. So you need to where your body. So you get
24:12 first this, this uh this uh you also, they are less um
24:40 believe they are when you look at end of this one, it's however
24:49 want. Ok. So the end it's not uncommon or the 78 to
25:05 four wire with six and 4 m and nine and 2500 line. And
25:13 you wanna look at the 25 by m grid. It will decimate
25:18 And what you will see is on comforter vision. You would have
25:22 I believe 2005 19. Thank So don't be surprised by that,
25:31 I want to see that. I that Yeah, what did you ask
25:46 that? She's listening to me and probably thinking about. So I'm
25:51 So this sounds like a problem about text book. So she's got
25:57 She asked watch her. I don't run in this. So she asked
26:04 OK. Do you know if we , oh, do we have to
26:09 the textbook? No, you You don't, you can answer to
26:13 mic so they can hear. Can hear me? Alicia? Yes,
26:21 can hear you. Oh Yeah. you don't have to buy the
26:26 I mean, you guys have to a lot of books. I've got
26:31 key references in there. If you're you're thinking of going into seismic
26:38 the one book, the introduction book to seismic interpretation is, is simple
26:45 it's a good book and it's pretty easy to read. And the one
26:50 mentioned, I probably mentioned one by Brown. That's a coffee table book
26:56 mean it's like coffee Table uh National in North America. Uh It doesn't
27:02 you how to hike or anything. . And then the one that I
27:07 , that's a good reference book if into attributes. But the, the
27:13 that's the uh, introduction to seismic . If you get any, that
27:16 be the one. Ok, Thank you so much. You
27:21 All right. And it shouldn't be expensive either. Yes. I,
27:26 also have a question. Do we it on um, WWSCG dot
27:32 Yeah, that's what I would And if you're a student member it's
27:35 a little cheaper. Ok. If want to become a member, do
27:40 put your information down as a How much, how much is it
27:44 , we tell me how many 77. Ok. She got
27:51 Ok. Oh, and she got for 77 instead of 97 by,
27:57 being a student member. Yeah. , it is. Yeah.
28:03 Yeah. Ok. Ok, Thank you. All righty.
28:10 Ok. I mean that there Yes. Ok. Uh let me
28:49 this. Well, I mean, I wanted you to do later
29:02 you know, I have a question anybody's there Oh yeah. Uh So
29:14 had me click uh continue spatially but I'm looking at the like lab
29:21 a and it tells me that put like a longitude and latitude, should
29:26 start over or should I just keep ? Ok. Well, sure.
29:47 so they are working separately and so um it's so great actor. I
29:56 it's good for the in the taking a class in person, but
30:01 student like they are not sharing the . So I don't know how do
30:05 can help them? And professors helping in the class? So they are
30:12 in right now. Ok. So share the screen. OK, let
30:16 ask, show me somebody who share though. No, none of
30:22 If they share the screen, you them, right? Yes. Do
30:26 do? They have cameras, do all have cameras on there?
30:29 they have but they didn't not turn on the camera during the
30:36 They don't want to turn them I don't, I mean there's a
30:40 there and this is mine because you know you in the email
30:46 So they asked me to uh doctor m asked me to bring a second
30:51 so I bring a second. Yeah, I think so.
31:09 OK. Yeah, we'll try to if there's something we can figure out
31:15 it's, it's kind of hard but don't think any that's all in order
31:24 you send me a time. so you said that. So just
31:32 me know to, to um I I I read that yeah you you
31:44 come at two that would be but talking to some other too but I
31:51 know. Did you uh did you ? Ok, well you give me
31:58 room at 245 or you guys just sit right next to you?
32:16 Thank you. Good for you. . Well, that's the same as
32:19 we just did. Ok. Um Jan. So thank you,
33:00 Um Let me, is there no one is sharing with me?
33:04 Yeah, she Jessica is sharing right . So can you uh can you
33:15 City of York? Yeah. How's going? Good. Always the it's
33:32 this way the first part in the . Yep. OK. What do
33:37 got ma'am? Um ok. So the beginning I asked about this spatially
33:44 warning um and he had me hit unaware. Ok. Let's let's go
33:53 . The CRS let's go select You want to read it? I
33:56 hit continue uh spa unaware before I over or that'll be fine.
34:05 on your upper left, what do need to do? And hopefully I've
34:09 this in the notes. Not, that far. I'm sorry. You
34:13 . Ok, right there, warmer, see where it says
34:17 You got a 3D data set. that then the also the other thing
34:24 see where it says automatic uh maybe one line detection method, maybe five
34:31 down. Yeah. Yep. Put the trace header fields. Now the
34:41 is gonna work, ok here. But it's good to have the trace
34:46 fields because other data you'll deal you're gonna have to wrestle with the
34:50 headers, ok? Now, if uh if you take the window you're
34:56 and it make it a little bit taller and skinnier like the whole
35:05 Yeah, so we can read the in the below. So grab,
35:12 , make that a little bigger. good. OK? So that part
35:19 the Segway world it's got, I know, maybe the C one C
35:25 , guess what that stands for So you ever see great grandpa with
35:32 cards in the computer? No, , that's OK. That's what we
35:39 . So we punch cards with that in it. So there's about maybe
35:44 might be a maximum of uh 240 . I can't remember. And it's
35:49 some of this information about who acquired data, maybe how it was processed
35:55 the projection is, et cetera. this case, I got the data
35:59 of the, from, from uh Zealand and um and then I re
36:06 it here. Uh But what you'll , you see, it has
36:11 a couple of notes about the first number, the last line number,
36:15 CD P number, last CD P . And it's supposed to be like
36:20 and 12.5 m increment on the Ok. Go down a little
36:29 And what you need to know is these trace headers are. So in
36:34 the way Petrel exports it is the coordinates in 73 the Y coordinates in
36:42 and the there are four byte OK? So we have, I
36:48 there's 240 bites in the trace OK? Four bites per word.
36:56 , you're comfortable with bits and OK, good. So um so
37:03 first of the X coordinate for patrol 73 the Y is 77 because I
37:10 it from a patrol project. Their line is five and their cross line
37:14 21. Now in Segway standard, current Segway standard, it should be
37:21 83 1 89 1 80 uh 71 1 95 like that. They're
37:30 So for different software packages and different , those numbers are gonna be
37:37 So you wanna always look at So if you go up, move
37:42 mouse up, so you've got those in and you see where it says
37:47 to scan right here. Yeah, in 5000 and then about two lines
37:59 . It's got a little scan you click that and it's going to
38:06 those four headers. Now what you the first one is the in line
38:11 it's saying, OK, it looks I got out and made a whole
38:14 of them in 52,051 1052. You the stair step. Mhm.
38:23 Cross line and it's starting at 1400 up to, I don't know,
38:28 2200. I can't read the top it and it starts back again.
38:33 1400 goes to 2200 back again. that is totally reasonable. OK.
38:41 it, it's is saying that the I'm gonna organize the data by
38:49 line first, in line second. . Then if I my survey were
38:57 north south, then either the XYX or the Y coordinate would be stair
39:07 , but it's not, it's So the fact of the matter is
39:12 , I see this kind of sort repeating pattern uh for each line number
39:20 it at present it looks OK. . So you can hit OK.
39:27 then on the left, you're going say OK. OK. Yeah.
39:38 now it has, now there are lot of windows and in, in
39:45 . So, oh, and this OK too. You can say it's
39:52 . Oh, let me, let say you're fa are you familiar with
39:57 ? Um Well, you're in I don't know how many, I
40:02 know how Germany is projected. Where's hometown? Um California Baker.
40:09 Ok. So California might have three four projections because the earth is
40:16 Ok. So what they do is fit a flat plane to local
40:20 So in the United States, we each state has several projections. So
40:26 has two. Ok. A western an eastern one. Texas has at
40:31 four. California probably got three or . And then the projections have an
40:38 like uh in California, you're you're gonna find highways that are called
40:45 Meridian. Like there'll be a, in Oklahoma City, there's a road
40:49 Meridian road and that happens to be line for the projection of eastern and
40:55 Oklahoma. Ok. But you'll, see that just like you'll have Townline
41:00 and, and so forth. So projections are always gonna be positive.
41:04 be big numbers during in meters and this one looks, this one
41:08 fine. Ok. It be positive the, uh, the range and
41:14 is gonna be two millisecond and uh , unlike all the other software has
41:20 range going, um, Z is down or positive of which is
41:28 So hit. Ok. Ok. , ok, for all, does
41:31 matter? Yeah. Ok. For . Yeah, that's good. All
41:37 . Now you need to open a and let's make your patrol screen bigger
41:45 I can see where the window icon , uh, maybe stretch it
41:54 I bet you. Yeah, you the little under property modeling has nothing
41:59 do with property model. But you the, where's your mouse?
42:02 Ok. Go straight up and you the little white square that says
42:09 Yes. No, you're clicking your . No, uh in the patrol
42:16 . Ok. Move your mouse to northwest. Keep going a little
42:20 a little more. It says window a little white square. Ok.
42:27 the right. Ok. One more to the right now, one more
42:34 for the act. What are you your f you don't have a
42:39 right? There's a lag but I what you're going through, you know
42:43 you want to go to. Oh , because you got the wag.
42:47 , I told you it would be . Ok. So once you get
42:52 that window, you're gonna drop down open a 3d window. There you
43:00 . See the second one says 2 window. Ok. Ok.
43:11 Now part of your wag is you're across the, the ocean.
43:16 that'll do it. I don't notice the TV anymore. They don't have
43:21 delays, they used to. But , ok, so now where you
43:27 in line and cross line, you're put a little check mark in front
43:29 that on the left hand input OK. Go down. Yeah,
43:39 . All right. And then hit other one. Ok. And now
43:45 the panel just above you, you it's not the fat hand that's kind
43:51 yellow highlighted. That's OK. You just leave it there and your mouse
43:56 a fat hand. So you're OK? So you're gonna like,
44:01 guess quick uh not quick. Hold the left mouse button and move your
44:11 . Hey, there you go. your 3D data. OK? And
44:18 the green is on top, that you got it oriented correctly.
44:23 Now, while we're here, the thing I said, put a quick
44:28 here and you get the ax you're not gonna get it with 2023
44:32 . So on that horizontal panel, the, the fifth icon from the
44:41 , it has a icon that looks an axis um up here somewhere.
44:49 go OK, go down into into your window. Yeah. And
44:54 go all the way to the right or five. Yeah. Now
44:59 go quick that show high display, uh show the axis. OK?
45:09 quick that and now you got the , OK? Now you don't always
45:13 to have that, but that was of the things I had in
45:15 in the exercise is now to stop , tumbling just, just quick again
45:23 your left mouse button. OK? was like, it's just spinning.
45:29 ? OK. Let's, let's race a bit and then you can catch
45:33 with the exercises afterwards. You're gonna , do you see where it says
45:37 Mi Cora 3D class? Go uh , don't you, I don't think
45:44 allow you to put a check So, but put a right,
45:48 mouse button on it. Yep. ? And settings, OK? And
45:58 we're gonna go to geometry. This what you wanna do with any of
46:03 data. So geometry up at the . Yup. And you're gonna look
46:10 these and see if they look OK? So I've got the end
46:14 are going from 1000 50 to 1450 an increment of one and 1400 to
46:21 , 2200. Those indices are going one. So common increments are
46:29 five, more than five would be except for I saw a recent um
46:40 survey that had an increment of But anyhow, um that's reasonable.
46:47 other thing you want to check are intervals and you see where it has
46:51 interval 24.99 and 12.503 um underneath the gem. Yeah. OK. So
47:04 and 25 is fine and there's a bit of round off in there.
47:09 . That's OK. That has to with the projection and stuff. Um
47:14 . Well, that's how you're oriented respect respect to north. Um And
47:20 if you got the data from uh service company, you wanna make sure
47:24 it's right. Um And then it's the first sample is zero down at
47:29 bottom, the first sample is the bottom sample is 3052 and the
47:39 is four. Ok. Ok. the shift is sometimes if you have
47:46 surveys that are in different elevations, might have to shift it. But
47:50 now we got one survey. So that's we are. Ok.
47:55 go to operations that's next to the . Mhm. Yeah. Ok.
48:07 . Now that's the histogram of the when it scanned it, when it
48:12 it. OK? So now we're go and we got the little buttons
48:17 the left set from the source. never do that because it's dangerous.
48:23 was I will say user defined, see that quick that and then you're
48:31 look at this. Now this doesn't it's throwing the data away. It
48:34 to do with the display. So minus 50,000 of plus 50,000 is
48:43 I'd say put in minus 25,000 and 25,000 in these. OK? You
48:52 minus 25,000. Yeah, I gotta a minus in it. OK?
49:00 then plus 25,000. OK? That's . Then on the lower the we're
49:11 if you go down where it says quality, it says eight bit,
49:15 , that's fine for this class. OK. Um Especially for you because
49:21 going a long distance and then we're go click that button that says realize
49:28 the lower right? Yeah. And hit. Ok. Ok.
49:37 . Now you see you got another . Ok. So let's unclick in
49:43 and cross line. Ok. And in line, the new ones and
49:53 Z. Ok. Ok. And let's get this so that you have
49:58 rotated with the Z with, with being up. So that means you're
50:05 have the, the green arrow on . Ok. There it goes,
50:18 got a handicap because it's gonna keep after you stop. Oh,
50:26 Ok. So let's, um, . So you're looking at it from
50:30 top, let's take the axes off by clicking the little axes icon.
50:36 , where was that at? the, uh, it was
50:39 yeah, that guy. Yeah. click it again. It should go
50:44 and then if you take your w do you have a wheel on
50:52 mouse? Mm. No. What you have on it? It's just
50:58 a, a, like a mouse . Oh, you just got a
51:02 ? Yeah, I have a, a way of making a bigger,
51:22 don't know how to make it bigger a mouse pad, do you
51:28 Oh, you just did it? , so, yeah. So you
51:32 roll it by dragging your finger across . So if you bring your two
51:37 , if you take two fingers and bring them together, it makes it
51:41 and if you push them. Ok. That's good. It's good
51:47 be young. All right. Um um let's rotate it to one of
51:54 uh vertical lines is vertical. So still got the little hand thing.
52:01 . Yeah. Now you're doing OK. Stop. OK. And
52:08 what you see is a volcano in middle and you're gonna get your hand
52:13 co ordination better as we go. there will be uh you,
52:20 where you had the hand, you're going to see three icons to the
52:27 are these little blue planes? You're click that. Yeah. Yep.
52:42 . Yeah. You got Yeah, , you're doing good. Yeah,
52:44 had a fine. OK. you had to quick. It really
52:48 . So the electrons go faster. ? Now there should be, you
52:56 be able to take your mouse on of those lines and just hold it
53:02 and drag it toward you or away you. Mm Should it sound like
53:11 ? Yeah. Should it be You gotta click it and see,
53:23 don't, I don't know how to it with the pad. So you
53:28 the the plane. Yeah. What it be doing? Because I'm hearing
53:34 like make noise. Yeah. So , we can try to I'll tell
53:39 what. Go on the left. the in line. Uh Yeah,
53:49 Yeah. Leave the, leave the . That's OK. But leave that
53:54 alone too. OK? Go back the N line where it says in
53:57 1250. The, the one Yeah. Click on that.
54:06 not, no. Don't click on word. Ah, ok. Now
54:10 highlighted. Now, see if you drag that puppy. Yes.
54:22 Now, go, yeah, go there and see if you can drag
54:26 . Of course, I don't know that's the in line or the cross
54:29 . It should have a little line it. Tell you what, unclick
54:36 cross line. Oh, now you it going. Oh OK. Now
54:41 see what you're trying to get OK? OK. So you figure
54:46 out. So let's take the, under if you take a quick outside
54:51 the cross line and the Z, just see which one the in line
54:57 . So why don't you do Minimize the confusion. So let's get
55:05 of the other line. C cross and Z on the left.
55:10 Yeah. Unclick the cross line uh uncheck the cross line. No,
55:15 gotta OK. Now you got to uncheck it. OK? Uncheck the
55:20 highlight the in line. OK? uh You deleted it. Um That's
55:32 . Go back to the wonder what did, huh? I don't,
55:40 didn't hit delete anything. I just What happened? Why I did
55:50 OK. Go to dig core The name highlighted right mouse then insert
56:02 below, it'll say insert in line , maybe way down. Um Is
56:10 insert, random line? No, do an insert and in line,
56:15 going down. It doesn't go There's no more down. Mhm.
56:33 . I don't know what that guy . I don't know either. I
56:39 know where it came from. you had something highlighted the, the
56:44 away. Ok. You should. . Go. So the D make
56:54 3D class down below right quick again insert what it, it, maybe
57:10 the first one. I, I know. See it doesn't,
57:16 I see. Hang on, I . OK. Go back to the
57:19 one again. They've moved things see it says intersection visualization with a little
57:26 arrow on it down, halfway down, down, down, little
57:31 . Now let's look at, let's go quick. That thing visualize
57:39 visible intersections, whatever that is. . That's the cross line. Damn
57:53 . I don't know what we did . I don't know what happened.
57:59 have no idea what this X thing . What if you unclick that,
58:03 does that do? OK. Highlight , delete it because we don't know
58:13 it is. Yeah. Whatever that and it doesn't have a way to
58:26 . Kind of annoying. OK. right. Let's, let's go,
58:34 go back to the D ME core and highlight that and hit the dowe
58:45 . Yeah, let's get rid of . Yeah, why not?
58:49 Now let's go highlight this guy in . Uh and you need the D
58:55 Cora 3d settings. OK? And redo what we did before with the
59:03 25,000 plus 25,000. Yeah. And a positive. Yeah, this is
59:17 when things don't react this fast. ? And you can just say
59:22 And then OK, there it is again. Now let's go and
59:30 Put a check in the in line . Oh it there OK? And
59:35 let's um instead of trying to do interactively because that, that really
59:44 I, I don't know there's a orange thing that's called player. So
59:52 . So move your mouse to the ? Uh to the left and then
60:00 and no, it'll be in the thing. Yeah, that guy and
60:04 gonna go go players and you're gonna down intersection player. There. You
60:10 good. OK? Now you got button. So it should be on
60:18 OK? Move your player a little out of the way, move that
60:23 box out of the way a OK? Good. And then you're
60:27 highlight H ad ny the word in . Yeah. Got it.
60:37 Now you see it says 1250. ? It's gonna go every 10th
60:43 You're gonna on the VCR buttons. you use betamax? Did Grandpa use
60:48 or um OK. You can click one. Let's see what happens.
60:54 go in a circle for you. ? You can hit the stop
61:06 you can hit the, see the arrow with the sty thing. On
61:11 . That means um what do you it? On the BC R?
61:17 , you can click that one. gonna go 10 lines to the
61:21 OK? So you click it, should go 10 lines and then click
61:25 again. OK? Now you should seeing geology. OK? You're gonna
61:30 volcanoes, the volcanic, you're gonna everything. So go to the notes
61:39 where it says. In fact, just do this. Do up at
61:42 top. You see where it says . You're gonna do save the project
61:50 Yeah. OK. And you're gonna the, you're gonna store it where
61:56 told you to store it. Oh under you, right? Or did
62:00 say put it on why he said put it on? Y OK?
62:05 I do have a, a good give it just call it uh give
62:13 day one. I don't know K with a K but that's OK.
62:25 Day one. OK. Good. it. Do I need to change
62:32 file type? No, no. , nope. Just hit save.
62:39 . It says 0% on the 77% 92 or 90 OK.
62:48 Now you're gonna go file and then . Shouldn't it be an exit
63:01 Ah exit, exit. Yeah. . So you're out. OK.
63:13 you have to do this every time wanna close your project down now hit
63:20 and you can see it, but can see it because I'm not sharing
63:24 full screen. I'm only sharing that of the screen. The whole program
63:27 out. Ok. That's ok. . So now you're gonna open
63:32 open it up again and make sure the old project that you called Cora
63:38 One. And you should be exactly you save it. Now, do
63:43 open it up in Petra itself? . Yep. Yeah. And you
63:48 be exactly where you saved and from you're in good shape. OK.
63:55 the main thing I want you guys be able to do today is open
64:01 , fool around and get a little for it. Save it, save
64:07 on the wide drive, right? drive, right? Uh Where did
64:14 say to save it? No, , you can't save and you
65:36 now you and then just sit there , OK, thank you. It
66:18 . Yeah, I, I don't to. One of you guys is
66:26 go clever and this is one of , you know, so I think
66:35 figure it out. Ok? The crazy stuff I had no intention of
66:44 it was this cool thing. very different way of looking at
66:54 You could do what this oh You're on the right time slot.
67:36 videos with no sound is gonna be . Beautiful. OK. I'm gonna
67:48 a drink of water then we'll fire again and with some lecture and then
67:55 quit. Oh the, the witch . Yeah, I have, I
68:09 the file. Yeah, I have on my computer. Yeah. But
68:18 have to, should I use Yeah. Sure. Sure.
68:29 Ok. Yeah. Yeah. Which one? Yeah. Well,
73:04 one, yeah, there was I guess might be lab two.
73:09 ? Yeah, that's where she said . So, what, uh,
73:16 we're gonna look at Zach here. , well, I, I click
73:26 one and pop up but you may remember where you shaped it.
73:32 I've been there. OK. that's, that's annoying. Um
73:43 hang on, I just saw something said four or 3D something. What
73:46 that? Uh OK. OK. it might be a, that's where
73:57 data are and there's another file that to that where the heck is about
74:06 , I think. And you go one higher, one level higher.
74:10 don't know. I mean, it's this PC, is it no
74:18 OK. Where are you guys 51? Well, y yeah,
74:35 what I was. And for some they called this Tora 3D plus C
74:42 . OK. So now I just it for the bundle too.
74:47 I from bundle which bundle? So we need to look who's opening
74:54 now, who's opening the pro I like. Well, yeah, let's
75:05 at because there's two bundles and now just assuming we got petroleum engineers in
75:22 or maybe like a bunch of geology , you know. So, there
75:27 be classes where they don't do hardly seismic though. And they've got bundle
75:34 . They're doing a quip. Reservoir simulator. And then the geoscientists
75:40 gonna be doing more of the geological . So, when you go to
75:45 bundle it will have a list of licenses are in there. So,
75:51 it have seismic shenanigans or something like ? Yeah. Yeah. That's probably
75:57 one why? Yeah. So I still be able to open your
76:06 Oh, that's ok. Ok. , it's the same one. I
76:13 in MC three but I think reading from when he went into the V
76:22 50% I was talking about. let's see if you can.
76:31 Click on the thing here on the , hey, woo hoo.
76:40 Bundle one. Jessica bundle one, one. Yes. Yeah, this
76:53 what you, this is how good get after you've had poker, more
76:58 than the spider had. But you to remember that too for future
77:06 Yeah. OK. Are, were you saying bundle one? Because
77:36 means we should have been doing this bundle one the whole time and not
77:38 two. I, I know Uh at, at my school
77:50 the engineers use, they use different . Talk about college, favorite
78:12 OK. Um Let you do what need to do. That's OK.
78:50 was wondering where your camera was Ok. Ok. So I got
79:10 , and my power on you're seeing she can see it. Yes.
79:35 , um gonna go to, you go to six o'clock, everybody having
79:40 yet. All right. So, sorry, I'm facing away from
79:46 but I can't do the mouse. we wanna talk is just about color
79:50 , the display. Ok. We've good and bad color balls. Your
79:57 , right? Nobody knows what your are. You don't have little brothers
80:03 sisters or nieces or nephews. You , they got a picture of giraffe
80:09 the shirt and a picture of the on the pants, right? Aren't
80:14 Stephanie? Aren't there people at work need that bad? OK. All
80:20 . So they know how to match . OK. So there's bad color
80:24 out there, color schemes. We look at multiple attributes in the single
80:29 , apply color schemes that will allow text, communicate these features to other
80:35 beings, not just to yourself. . So they're good practices and bad
80:43 in human eye. We've got cones receptors, the, we've got three
80:49 of cones. Uh Turkeys have So they see color a lot better
80:56 us. That's why if you're a hunter, uh you have to be
80:59 have really good camouflage and the rods more for brightness, the levels of
81:07 intensity of the light. So your vision is more determined by your,
81:13 your rods. Ok. Men and , you think color is a little
81:19 different. Um, on the I've got this for my daughter and
81:25 right is kind of how I see on the West. We see
81:29 you know, and there is a the colored gene is actually on the
81:39 chromosome. Ok. So men have X chromosome, women have two.
81:46 you've got an effective defective gene, chances are then are going to have
81:55 color blindness or combo color, you , red green, color blindness,
82:00 cetera. It's about 15% for It's only about four or 5% for
82:05 . But then for women because they two X chromosomes, the R GB
82:11 don't have to line up. So of being trichromatic, many women are
82:18 chromatic and they actually see color more than others. Our culture from all
82:25 , we're really not tuned into Uh So we don't have the vocabulary
82:32 you can look this up tetro chromatic , et cetera. And a lot
82:36 them are very successful artists and interior and stuff like that. Most don't
82:42 that they're particularly sensitive to color except when I wear my clothes, it
82:48 really be, you know, have stomach and stuff like that, but
82:52 , they're very sensitive to bad color , but take a look at
82:56 That's quite interesting. Uh We've got color models and that's the red green
83:03 color model. You're probably very familiar a red light, a green light
83:07 a blue light. And if I the red and the blue light,
83:10 get magenta. If I mix blue green, I get cyan. If
83:14 mix green and red, I get . If I mix red, green
83:18 blue light, I get white. if I don't mix any of
83:21 I have black. Ok. So what we're using on your computer screens
83:26 a printer, it's subtractive. So just the opposite and the colors.
83:32 you buy the printer cartridges, you're with Cyan, magenta yellow, then
83:37 might have another one for black because you make Cyan magenta yellow, it's
83:41 to black, but it's a dirty and it cost three times as much
83:44 the black plant. They don't want do that. So if I'm,
83:49 I add Magenta Inc and Cyan, on, yeah, if I add
83:58 ink and cyan ink in the back this picture, I'll get blue and
84:03 I add, uh, yellow ink Cyan and I'll get green and like
84:10 . And if I had all I'd get black. So if I
84:13 print anything, I just have the two. Ok. Oh, here
84:19 and I had a one time 28 each for a little cartridge. Now
84:23 got a fancier printer and it was and it was like $80 per per
84:31 . Ok. For the uh fancier . Oh, and then you need
84:35 black one too. So sometimes they it cmyk for black K for
84:41 Ok. Um And any graphic it basically will use one bike.
84:53 one bit has eight bits, two the two powers, 42 to the
84:59 power is 82 to the four powers 64 1 28 2 to the eight
85:08 is 256. So I can have levels of red, a green and
85:15 blue color. So we're gonna go 0 to 255. That's the way
85:19 people do it. And um so is, if I go RGD two
85:26 , it's a three component vector. red is gonna be 255 00,
85:32 is gonna be 0250 blue 002 Cyan 0255255. Uh Magenta is like
85:43 . You see how it works? . And I work now we also
85:50 , yeah and um so on the , I have 15 million. I
85:58 a way my throat down again. gotta tighten this up. So when
86:12 uh graduate from high school, you to have a uh a picture.
86:19 back here, I know the kind picture he had, he was standing
86:24 to a tree looking like this, know, kind of like Oh,
86:29 gonna be a litigation lawyer or That kind of look. Right.
86:33 then there's a thought for, looking towards the future. Now at
86:40 72 the future is kind of yes. You know, but
86:44 so this is a classic high school picture. Do you have those kind
86:49 pictures in Columbia? No, but don't have that kind of thing.
86:56 knows exactly what I'm talking. You have no borders here in, don't
87:00 litigation? You know, got in accident call Anderson and Anderson.
87:06 Here I'm gonna use 256 by 256 256 colors 24 bit color. By
87:12 way, that's, that's the way cellphone camera work. Like you all
87:18 uh, 256 bits for each then we dropped it down to 16
87:26 . That looks ok. And then you go, the closest I could
87:31 to having an imbalance with, the 256 which is what we're gonna
87:36 in patrol and you can see, , it looks a little spot,
87:41 , looks like I may have had or something like that. My,
87:45 jacket has stains on it. That's . Yeah. Ok. So for
87:52 attribute I would say none of us basically, you know, like the
87:56 and the data 256 colors is But if you start to combine
88:02 you really need to have more colors . And uh psychologically the colors have
88:08 do your sensitivity, color has to on your familiarity with an object with
88:14 data. Uh seismic data. Uh classic example uh 40 years ago and
88:22 and Don Hart Robb was Cheryl Remember Cheryl Tiggs? Oh OK.
88:28 , she was too young for you the time. OK. She was
88:32 uh the co uh you know, , the beautiful model of the,
88:36 the day. OK. OK. uh one of the guys at the
88:41 meeting showed Cheryl Teas just like this you know, it went the full
88:50 gorgeous. Then you drop the colors to about one quarter of the normal
88:56 . Then the women in the they felt a little better because Cheryl
88:59 wasn't so not so pretty anymore. looked like, you know, like
89:04 a or something like that. And as she went down to what we
89:07 for seismic data, it was pretty . OK. Uh Here's a time
89:13 I have uh who attributes covered against other. Uh convergence. How much
89:21 they coming towards each other and then orientation. So I'm using a two
89:26 color wheel. Um Gray is gonna parallel blue is pinching out to the
89:36 yellow, pinching out to the south , pinching out at 100 and 20
89:43 magenta pinching out at 60 degrees Cyan minus 60 green at minus 100 and
89:50 OK. Um Looks. OK. of cool. We'll talk about data
89:54 this later. I got 65,000 Ok. Now, here I brought
90:00 into 4096 and at one time I able to trick patrol into doing
90:06 I can't do it anymore. You ? Well, we've lost, it's
90:11 pixelated and then you go to Now it looks like really coarse.
90:19 . So that's color depth. So got several multi attribute display tools.
90:28 um by the attribute you can think here is a satellite image of Houston
90:35 here is the weather map on top it. Those are two different maps
90:39 I wanna combine. So how are gonna do that? So start out
90:43 over plotting and I'll go through the over plot. Let's plot the envelope
90:51 is going to be the strength of reflection in polychromatic color bar with red
90:57 high reflection strength zero being no reflection . OK? And then overprint the
91:06 wiggle traces on top of it. how do we do this? We
91:10 it in a printer and we printed for Cheyenne and Mata then yellow.
91:18 . And it was the printer was out, rolling back in each time
91:21 the last time black but actually support a picture like this, it costs
91:29 $100 to make 11 plot back in . Uh Here's one that's commonly used
91:38 another over plot uh for an When you take Leon Plat, he'll
91:44 talk about anisotropy. And um the , we've got an arrow that is
91:51 to the direction of the fastest That's the orientation, the length of
91:59 arrow is proportional to the strength of f of velocity. And then the
92:05 is the difference between the fastest and velocity. OK. So where is
92:15 magenta and uh magenta into the red isotropy where is blue and Cyan
92:24 An and in this case, the end isotropy is controlled with a strike
92:29 fault in uh North Texas. Let's look at red, green,
92:34 cmy, an image that is 16 time. So through Seismic amplitude,
92:42 32 Hertz, oh I see some that are tuned in at 30
92:47 32 Hertz and then uh a 40 48 Hertz. Um We're looking at
92:54 data that's been filtered basically the 1632 48 Hertz and asking what's the strength
93:00 those 3 ft? What's the magnitude that data? I'm gonna combine them
93:06 , green, blue. OK. color. Notice that. Oh,
93:11 is tuned in its strongest than which doesn't surprise me because that's what
93:17 image shows. And then, what's this yellow? Well, I
93:22 yellow is mixing red and green about . So that means this guy is
93:29 in quarter wavelength thickness and I haven't about tuning frequency. We'll do that
93:35 but at about 20 Hertz halfway in . And, uh, Cyanne,
93:40 , maybe here. OK. I some Cyanne cyan there. That's between
93:46 and blue. Oh, that's tuned maybe at 40 minutes. OK.
93:50 it's a color bar. It's a color scheme that's used, particularly for
93:55 magnitude components that's natural to anybody who now, not tree thinkers like
94:04 but the rest of us more excessive people who have to have their Crayola
94:11 in the exact same correct order. . Not artistic. All right,
94:24 color bar that is called um uh Carrick from a company called Crosser Fling
94:35 again, red green blue, 1926 Hertz. Notice how these channels show
94:40 very, very nice. OK. we can also use CMY and
94:49 we're gonna use more for edges. the names of their attributes are kind
94:55 silly and we'll talk about that when talk about attributes, but they have
94:59 that's showing kind of faults. They're plot that against Cyan. Then one
95:07 estimate that sensitive default called semblance. gonna plot that against magenta and then
95:13 magnitude which you all understand, you , the dip magni local dip magnitude
95:17 the reflector, they're gonna plot that yellow. So I've got three images
95:24 here they're co rendered and where all attributes indicate a fault. If I
95:32 a gentle yellow I add them, get black. OK. So where
95:37 have black, that means oh all three of them are indicating that
95:40 are false. And where I have uh yellow thing, well, it's
95:46 dippy but it's really not false. where it's um I mean there are
95:52 areas where they're red so it has uh a high assemblance and a little
96:00 of uh this uh gradient structure tensor . Well, they both of those
96:04 anomalies there, there's a little better , same people that you and,
96:13 you can see where all the the attributes line up. I get black
96:20 where they don't line up, I get an a color that shows you
96:27 one or combination of who is So it's a way of presenting three
96:33 of information at the same time. we can also compute a negative a
96:40 like using Microsoft paint. OK. that's what I did here, I've
96:44 on the left a red green blue and here's ac my image. So
96:49 CMY remember I said it's attractive people that kind of hard to get your
96:54 around. Mathematically, I take white , subtract the red green blue color
97:05 I get this. So if I 255255255 from 255255255, I get whack
97:17 . And if I, if R is uh blue is uh 00255.
97:25 I subtract that from white, then end up with 2552255 zero, that
97:34 to be yellow. OK. well, in fact, here's the
97:40 blue subtract blue from white, I yellow. Hey, here's a picture
97:45 me and then Microsoft in there's my . OK. That's what it
97:54 And you can do that, you , in invert the section. That's
97:58 you do it in Microsoft paint. , how is this useful?
98:03 there was a paper by a guy Petro Explorers using a software called Open
98:09 uh that grow real. Here's his green, blue image of seismic uh
98:15 spectra magnitudes, let's say 2040 60 just to pick a number. And
98:22 was interested in this zone and here what you see he sees, I
98:26 see anything just black. Let me it. I wanna look at the
98:31 things, not the longer thing. by inverting the color bar, now
98:36 can see the little reflection and so and the tuning in there.
98:42 HLS. Those are gonna be my . I like R GB and CMY
98:46 . But you, I, so got three axes and now some people
98:53 say uh you saturation and value and patrol, they'll use both of
99:04 you know. So you get a confused but H OS OK. Let's
99:09 with L for lightness, black uh colors, pure colors, pastel
99:21 Why? OK. You blue at degrees magenta at 60 red, 120
99:29 , 180 green 240 Cyanne 320 blue or back to zero. OK.
99:37 gray. That's a little harder to your head around but think of a
99:41 store and I'm gonna add a certain of tint. OK. So I'm
99:50 go from orange. Who? Mm They don't like senna.
100:07 I'm gonna go from green two I'm gonna go from blue to pet
100:18 . OK. So these colors that use like bill looking cloud blue.
100:25 OK. Those are, that's what doing but we're adding a chance.
100:32 . So you go to Sherman Williams buy paint. They're gonna add these
100:36 pigments, Diane magenta yellow and OK. So those three define a
100:43 dimensional space in this case, a . So when I look at just
100:47 of them, I might have ac cyclical attributes. So dip aute I'm
100:56 around the as you from 0 61 82 43 23 60 which is zero
101:06 the dip magnitude I might have zero the top of my head. So
101:09 would be zero dip so gray to north will be blue to the south
101:14 be yellow. This way will be a dirty green and this way will
101:19 a salmon color. OK? Are good that way? And then the
101:27 and the peak frequency here we won't all the way around because this might
101:32 10 Hertz in red and 80 Hertz blue. OK? And if it's
101:38 or in this case, it's white it could have been great. Um
101:44 no amplitude so whatever frequency it is mean anything. OK? And then
101:49 can do phase and envelope as So here's the first example back in
101:56 uh envelope which maybe one or No, nobody got to it because
102:02 were using package two OK. Uh and then generating composite image. So
102:11 actually have a two dimensional color So phase goes around the circle and
102:17 goes uh from black to a pure . And here you can see,
102:22 know, I think that pattern here the same as this pattern. This
102:26 is the same as that pattern. it's easier to track correlated across
102:32 Commercial software uh using two attributes, is going to be sensitive to
102:40 You'll start playing with that tomorrow. call it variant and um patrol and
102:47 and then the envelope is how strong the reflector. So here they're gonna
102:53 , if it's, if it's weak uh a strong edge, you're gonna
103:00 black. And if it's a weak a strong edge and high magnitude,
103:07 might have kind of a dirty red then here they got kind of more
103:12 and yellow stuff. So you can uh here's a channel coming through.
103:16 see the edges and I see the what's in the channel and I see
103:21 edges a color blending. OK. physicists are gonna be real comfortable because
103:33 real comfortable with multi component data. XY and Z components, the vibration
103:42 or ocean bottom seismometer. So, I shouldn't point there to the and
103:52 keep dropping or so. OK. um I got three images. Image
104:03 has a red component green and the , every, every pixel on the
104:09 got a red green, blue Any picture you show same thing for
104:14 B and image C. Well, I wanna be A and B,
104:18 gonna take a fraction alpha alpha is be between zero and one, let's
104:24 0.5 and one minus alpha which is right? And I'm just gonna add
104:32 components. I'm gonna add the weighted . That's exactly how you put two
104:37 together. And this is all done the computer hardware and a software package
104:43 was agreed upon late 19 nineties called GL for Open graphics library.
104:54 Then you wanna blend A B and . Well, I'm gonna take beta
105:01 of B and one minus beta of and add them. But F was
105:10 blending so I can multiply it all . This is how you would blend
105:14 , right? So here's a Survivor . I was writing a paper with
105:20 buddy Chopra and uh we wrote the and choose and we had a coherence
105:30 and a, a positive curvature The one on the lower red battery
106:07 not dead. A Gupta. I was waving my arms. I'm
106:23 , I'm connected the wire. So I've got a um image
106:32 first thing you're gonna generate a A . OK? About the same
106:37 Then here's image two. Then you're right quick on. Oh I'm gonna
106:42 image two and put it into we call it in the memory and
106:54 I'm gonna click on it. I'll, I'll, I'll just do
106:57 here in a bit. Then I'm quick format shape. You gonna feel
107:06 ? I'm gonna get it from the board. That's the word I was
107:09 for. OK. Then I'm gonna transparency and here I am for the
107:17 one and I got three images. one is my base image. This
107:23 is uh I use 67% transparency and 1 50%. How do I figure
107:29 ? Well, I wanted to be when I looked at those formula and
107:34 this one is 50% transparent on a background instead of black, I have
107:39 , this one's 67% transparent on a background instead of medium gray. I
107:44 light gray and then they can move guys on top of each other.
107:52 ? And so let's say you don't me. And I'll just take this
108:02 here. Take this picture here. know what I'll take these three
108:10 Control C I'm gonna insert a new . Stop sharing. I just
108:25 Go ahead. You're on top of . OK? So I just put
108:32 three guys here for now, I'm generate. Oh Yeah. Go
108:47 Am I waving my arms? I . OK. So I'm gonna move
109:05 guy over here. I'm gonna make fairly big. I'm gonna pick the
109:14 . They doing a web. I'm go over here to the red
109:20 I'm gonna hit control C put it clipboard, go to the blue
109:25 Highlight it and then you have to the right mouse button really hard to
109:32 those electrons faster. OK? I'm hitting it hard enough. Ah There
109:39 is. Hit it hard enough. electrons went fast enough. I go
109:43 format shape. I'm gonna fill it default in this implementation here is uh
109:52 blue circle or blue solid fill. you're familiar with gradient, you're familiar
109:58 texture, I'm gonna use a uh clipboard right then happens to be
110:07 Kind of got oh Because I made with the same and then here's my
110:15 . You always can integrate those It's kind of a good Survivor skill
110:21 you're writing a, you know, might have a, a false map
110:29 a geological paper and then you've got seismic survey or gravity data, whatever
110:35 is and you gotta combine them, new blending and powerpoint works works.
110:40 ? OK. All right. Now can get a little more. I
110:50 you something very simple. Here's a axis. Now you're gonna dream about
111:00 tonight. This is how I stumbled it. I went to Saudi Arabia
111:06 had to give a talk and I terrible jet lag nine hours difference.
111:10 they had me working in their patrol because they wouldn't give me any data
111:14 of Saudi Arabia. So I couldn't and I figured out how to do
111:20 . So I'm gonna use monochrome monochrome black color bar. OK?
111:26 we're gonna make this part opaque. I'm gonna see white transparent at
111:35 opaque at a strong negative value And I'm gonna plot this color bar
111:41 seismic an and what that's going to is allow you to go from
111:50 still see the colors underneath. But over flop the size of data you
111:56 this kind of thing. You can the same thing with saturation and we'll
111:59 this in the petrol lab non We're gonna use a Monaco gray color
112:07 and of its flat dip, the , you means absolutely nothing. So
112:14 gonna make it. Oh here's a dip. We're gonna make it
112:17 so it'll be great. And if a strong dip, I'm gonna make
112:21 see through. So I see the and in between is in between and
112:27 you can do three things if you to. OK. And we'll,
112:32 just do these, I think you'll comfortable with. So here's a,
112:37 dip ASU image volumetric estimation of dip uh from a different New Zealand Survey
112:45 the colors correspond to the ASU but of the areas are relatively flat.
112:51 the dip magnitude where it's white, black dip where it's black, it's
112:56 strong dip. So here is cor dip Asmus and dip magnitude. I'm
113:05 this for my dip magnitude color So at zero degrees, I'm gonna
113:10 gray and in five degrees or I'm gonna see whatever the depth
113:15 So where you have gray, this flat. OK? And this is
113:20 two D color bar that really I by coin. OK? So zero
113:27 is gray and strong dip in the is blue, strong dip in the
113:30 is yellow, et cetera. Let's coherence on top of it there.
113:36 gonna use monochrome black. So low , I'm gonna make it opaque,
113:44 see black edges of my fault blocks then high coherence. I don't have
113:50 fault, they make it safer. we'll be able to do these in
113:55 . You see the little green I did those in patrol.
113:59 Bump maps, you'll see this sometimes you can do it a little bit
114:04 , in patrol. It's not implemented well in some of the other.
114:07 as in some of the other software . Um but here is a,
114:12 seismic vertical size and the time Let's look at coherence. OK?
114:21 where you have black, those are this example, mainly false edges and
114:28 know, some of these areas might Strat democratic in hearing do. Now
114:35 can apply shaded relief. So stung , we're gonna think of low coherence
114:43 a structural, high and high coherence the structural well and then illuminate it
114:50 a light. OK? And you this kind of image. So this
114:54 where I started and then I got and now I can put that on
115:00 of the Seismic Amplitude and I combine things quite nicely. And of
115:07 I can change the shading interactively. one in power point, the emboss
115:14 if you've ever used it. So a good color bars if uh
115:19 attribute is single polarity, so single might be the magnitude, it might
115:27 peak frequency, it might be it might be what is the amplitude
115:34 the of a positive reflector? Then you wanna use single gradation of
115:40 bar. OK. So white to , white to black, uh rainbow
115:46 backwards, rainbow or you can even them piecewise rainbow, that's, that's
115:51 too. Then if I have a attributes, so phase goes from 0
116:00 360. Uh avenues goes 0 to strike goes from, let's say minus
116:07 to plus 90 then then they become east west strike is the same as
116:12 to east strike. Ok. then I wanna make them go in
116:15 purple. Uh So I'm gonna use cyclical color and then the third example
116:23 for dual polarity attributes. So the polarity attributes are but yours.
116:32 OK. So I can have zero crossings and troughs on the seismic
116:38 because that's the most common one, curvature, zero curvature, negative
116:45 Those are the most common dual po . And there the trick is make
116:52 zero value be a neutral code. we have three neutral colors,
116:59 gray and white. So what you to do is use a neutral color
117:04 those areas that have little interpretation of . So nobody's really interested in something
117:11 a mono mono just, just dipping plane from one direction flat. We're
117:16 interested in strong like the edge of fall, right? Or a sin
117:23 we wanna enhance that. What's the noise ratio at a zero crossing?
117:29 very good. The noise is let's constant noise and then my signal goes
117:33 zero. I don't wanna emphasize that actually wanna de emphasize it.
117:39 Now, effective one D color If you're looking at the internal
117:45 this comes from a guy called Art who worked for landmark graphics. And
117:50 here's just the amplitude. Uh but I wanna look at edges,
117:59 look at edges. You want your eye, your rods are best
118:04 seeing edges and at night, you , night vision you see the edges
118:08 things. So we got a couple different edgy things. Gray scale.
118:13 . Um Landmark uses this like blue , blue black, right? A
118:20 colors if you, you know what mean by Tia, does that translate
118:25 any languages you guys speak? So like an old time photograph kind of
118:32 brown, tan black. OK. kind of I have to come up
118:38 a picture but those were great polychromatic like garbage for OK. Then to
118:51 them, you wanna use kind of typically your greyscale with polychrome for the
118:59 with polychromatic for what's between the So here he's got an attribute called
119:07 . Then you got sweetness with uh . A bump map discontinuity. And
119:13 he's got sweetness with a posse and discontinuity. And here he's got sweetness
119:17 relative amplitude grading and they all worked well looking at two things together.
119:24 one this guy Hodler Jacobson did it pare uh and he hit sequence
119:33 He's got an in size channel Variance is his version of coherence.
119:40 . So they're looking at edges of channel, we've got our root mean
119:45 amplitude. So what is the take within, let's say a 20 millisecond
119:54 . Uh So 11 samples, let take the square of each value,
119:59 it's positive or negative, add them by 20 millisecond. OK. So
120:05 what he's done is, oh I strong reflectivity in this channel, Neander
120:13 . OK. And weaker reflectivity in floodplain outside and here's a coherent showing
120:20 edges that's co render up, And here's his image. He's got
120:26 vertical slice here, here's his horizon . And now you see this channel
120:32 all the feeders going into it pretty picture. I mean, it's kind
120:36 like nice wallpaper just by blending two things. OK? So a pitfall
120:45 using a neutral color to display zero . I did this picture in this
120:52 like 1518 years ago, maybe 20 ago using uh steel frame will be
120:59 . Here's a good color bar, . I love greyscale. Men tend
121:03 see edges better with men tend to faults better on gray day. I
121:11 do. Women have a little better vision. They can see far from
121:15 background, at least most can or they can. OK. Um Here
121:21 so this, this is a good bar looking for an amplitude white means
121:25 a zero crossing the uh work on . Here's the water column is white
121:33 was the default color bar in Geo . This is good. And here's
121:38 you'll see a lot in publications where use MATLAB or something like that.
121:42 , I gotta use color. And do you see? You see a
121:45 lot of green. Uh, and don't see the troughs at all which
121:50 white. Uh It's just a bad bar with faults on them. I
121:57 color coded faults really nice. On gray scale. I get very confused
122:03 I put color code default on the background. But again, most women
122:07 know don't seem to have a problem that. OK? So that's
122:11 that's a personal thing. OK? Displaying continuous data with colors that are
122:18 adjacent in R GB space or HLS . Here's the first paper on curvature
122:25 seismic data on a horizon and he's maximum curvature. It's gonna be showing
122:32 , which is the most positive and most negative and what you see is
122:38 lot of East West southwest. So South William in, I think he's
122:43 at bad picks, acquisition, footprint bad pick. But those high amplitude
122:50 are right about zero curvature. Then the same paper, it says,
122:54 , if I wanna emphasize my faults are gonna run from blue to
123:00 I see them better if I is black out the middle part and then
123:08 color, these colors aren't adjacent to other in red, green, blue
123:12 H OS or anyhow, it's a paper but four colors and then interpolating
123:19 colors. You'll do this as an in line dip component, cross line
123:27 dip component. We're gonna calculate the . And then what we have is
123:34 your computer screen, you probably what do you got 1600 by 1280
123:42 maybe? And the survey you have maybe 800 by 800 boxes. So
123:51 gonna plot it, use the whole . I've got to interpolate the data
123:58 my bins through the pixels on the from body as au they di ASU
124:07 OK? Here is a pixel uh minus one. Here's a pixel J
124:13 the value in between at pixel J wanna get, I wanna get
124:19 right? I wanna get that. what I get, that's what I
124:24 get from minus 178 plus 172. wanna get plus 178. But what
124:30 get is minus two because it's interpolating . It doesn't know it's a
124:38 OK? So here's my one here's the other pixel and a pixel
124:45 between right and in the middle. here's the data set in patrol time
124:53 or dip avenue. The default is interpolation. I don't have any yellow
125:02 here, which would be more about . Then if I go and turn
125:12 interpolation off is called the noun. I have the yellows, I have
125:18 lot less blue, you know what saying? But you'll see this in
125:24 lot in all the commercial software. ? Just the way it is.
125:28 then of course, I can add . Um, two more slides then
125:39 have when you're slicing through a long . So you're gonna pick a horizon
125:46 then you're gonna try to extract data it. Well, my horizon,
125:52 might have picked uh you know, and two milliseconds, 1000 and
125:56 And then in between, it'll be uh 4.38 it's got to interpolate,
126:03 gonna interpolate vertically. So the phases I'm showing a little piece of a
126:13 on the left. I'm showing the 90 degree phase rotated version here,
126:25 the original piece of the trace. make it 20 sample. Here's the
126:30 which is the some of the square rooted that's pretty good and continuous,
126:37 continuous. Here, I've got a skip goes from 180 to minus 180
126:44 cycle, skip another cycle, skip cycle, skip a little bit discontinuous
126:49 not too bad. So what we to do, we have to take
126:55 original envelope data cosine of the generate original data here. Fine of
127:04 face is the envelope. Calculate an part. I can interpolate these guys
127:13 they're continuous. Then I have to the envelope in the face.
127:19 The data set. You're working with of the legacy over the core
127:24 Here's a, this guy happens to uh a volcanic till here's another tool
127:29 another two and another T and another and here uh instantaneous envelope looks
127:38 instantaneous phase. Oh Gotta turn the off. I took care of
127:46 Then here is the time structure Here is the amplitude. What uh
127:53 picked was a, a trough. here is the instantaneous phase along that
128:00 . Well, I picked the I should be getting minus 180 I'm
128:07 every color of the rainbow. it even goes from minus 200 to
128:11 201 and it's interpolating, it's shooting 180 minus +18. And then
128:18 ah we use that approach where we hope transform the data and took the
128:25 tangent on the horizon. And now get this magenta color which is 180
128:31 eight. These are some of the you have to deal with and I'll
128:39 this one because we won't be doing either. The best color scales are
128:44 that have analogs every day. Human or experience hot and cold are graded
128:50 great rainbows, good shaded relief U is a natural choice for attributes
128:56 their sick phase as a music strike of discontinuity show a best in monochrome
129:03 scale SIA some of those flus choice discontinuous color bars to prevent the data
129:10 speaking for themselves. So you want use single or double gradation uh scales
129:17 this is Alistair Brown like the prints 3D interpretation. And then you want
129:21 use a neutral color brown for having low information, contact a white
129:26 black for zero. And I think is a I could end with the
129:34 , but we'll skip that. It's o'clock guys. So what kind of
129:40 questions do we have before we Anything from here in Houston?
129:57 Because we are, we are that's up to you guys. You're
130:03 right with that. Can you see screen? Ok, you got your
130:07 , you see it better? All . Well, if you're comfortable with
130:10 , I'm ok with that. so we'll meet here tomorrow 830.
130:15 , but what we can't do, can't bring food and drinks in here
130:18 Jade will get mad at us. right. Uh What do you wanna
130:28 latte or uh give your uh Ok. Um Any questions from Jessica
130:40 you mentioned assignments? Like the uh lab, the, the exam date
130:47 think is what's our exam date? 1015, 15. So sometimes before
130:58 15th. So what I'm going to and I'll actually show it to
131:03 Uh I gave, I gave you list of the labs and then Utah
131:09 gonna have a checklist. Now, can do the folks remote.
131:12 I can do the, the two who are remote. Uh, but
131:16 gonna go along and say, all , you did something check.
131:24 not embarrassing. Check in a different . Pretty good. Another check.
131:30 . Um, gonna be simple because a lot of work. Ok.
131:35 everybody's got different backgrounds. So, , you've used patrol even before,
131:39 at least a little bit. Some you have done interpretation. Some,
131:43 never seen seismic before in 3d. that's ok. All right. So
131:49 , we're gonna try to, it basically makes, let me tell
131:53 this, it's really hard to copy somebody else. It takes special computer
132:02 to know how to take somebody else's and get it into your project.
132:06 mean, I could teach you how do that. But anyhow, so
132:09 gotta do it yourself and uh it's . You know, so like,
132:14 when you pick horizons, it was , oh, it follows like,
132:20 not done at all. Total It follow. It honors the seismic
132:26 , but geologically doesn't make sense or the seismic data and geology,
132:32 Because sometimes you have to push your through where the seismic data is ambiguous
132:40 noisy. Or for instance, if take a horizon and pick right across
132:45 fall because heat and drops the line the fall, which happens a
132:52 Uh That doesn't make sense geologically, you'll find out really quick what I
132:58 about like, embarrassing and? Ok. Ok. Is good enough
