| 00:00 | Yeah. Mhm. Shit. but they ignore the fast forward. |
|
| 00:43 | , okay. Okay. Last time had looked at basically, high |
|
| 00:53 | but non barred in part. So saw two faces. Tracks one for |
|
| 00:59 | grain system where we actually saw Uh lieutenant mega ripples formed in uh |
|
| 01:09 | , uh increasingly high energy of his build up just before the breaker |
|
| 01:16 | And of course, we also saw in the surf zone. And then |
|
| 01:23 | going to be oriented offshore, forming rip currents and also a longshore uh |
|
| 01:31 | to buy it longshore currents. But also saw a fine grade equivalent which |
|
| 01:38 | was missing the dudes. So that be the pretty much what we have |
|
| 01:45 | , I had thought earlier before we looking at uh four straight material. |
|
| 01:52 | third setting is one where there is ball and that one has a somewhat |
|
| 02:00 | of situation of fascist versus preservation potential from just a pictorial point of |
|
| 02:08 | we got our longshore trough. And not shown is the rip channel that's |
|
| 02:14 | through the bar. And so that's to look something like this. Uh |
|
| 02:21 | got series and your cash bar coming an angle. Longshore point moves down |
|
| 02:31 | off to. Oh God, I had uh meant to show |
|
| 02:42 | Uh but you see in this case the ways are coming in this |
|
| 02:48 | there's an offshore bar over here, there's also a series of bars here |
|
| 02:58 | are at an angle. Yeah. what you can see on the inside |
|
| 03:11 | the rick chance resident launch trough cutting the river, jet, troll, |
|
| 03:19 | , troll. Yes, there's the this hand ahead here. And uh |
|
| 03:34 | were some slides I meant to put but forgot this one though. It's |
|
| 03:39 | little better here. The plays This is 100 years uh Again breaking |
|
| 03:49 | and bar and you've got all your control, we'll be back and |
|
| 03:58 | It current flow from control to the that's young dramatically here are troll and |
|
| 04:19 | in walks in here. Yeah, we can break that into fishies. |
|
| 04:25 | huh. They're down in here Uh So wait build up, wait |
|
| 04:35 | complex. You've got this bar system said spilling into home short trough. |
|
| 04:45 | then uh here we get Okay. , wave current area. This actually |
|
| 04:54 | think you're in the end of the slots coming off the ship. Now |
|
| 05:03 | bar look something like this is it's into the troll. So you got |
|
| 05:12 | relatively well low to high angle slip here. You see it near the |
|
| 05:19 | , press. Uh You've got something Phil Yeah, trouble. Say she's |
|
| 05:29 | down. So this is think of as a down stream of pretty Oh |
|
| 05:36 | tricks. Yeah. So there we that bar comes in through here and |
|
| 05:44 | on top of is trough film. going to be Its force enough going |
|
| 05:50 | be 12 across stratified gravels. Civility cost section. Now the problem is |
|
| 05:59 | Yeah, this bar is migrating onshore going to get cut by the next |
|
| 06:06 | . So what's preserved is actually not the highest in the service out when |
|
| 06:13 | lost emotional surface. So, imagine is that system by greeting Ciba pro |
|
| 06:27 | notice this far is trump aided by deepest scour, which is a good |
|
| 06:35 | . So what we end up getting they scoured surface. Yeah, this |
|
| 06:43 | troll Swanson bar has almost no preservation . So what we end up getting |
|
| 06:53 | a vertical section is this offshore initial saw earlier with the non bar |
|
| 07:04 | but then said upgrading up into the from the execute surface offshore migrating channel |
|
| 07:13 | migrant trough. It's complex interval rating into attachment. So, |
|
| 07:21 | what happens to the brain side. this abrupt increase of praise side? |
|
| 07:27 | is a scout. Just be a example where walter's law doesn't actually work |
|
| 07:34 | of this. The weather service. . And then of course, it's |
|
| 07:42 | what total beach and that's because we've surf, some deposits coming. Read |
|
| 07:51 | surf zone ways of current coming and the return to squash these little splash |
|
| 08:00 | winnowing that goes on there. This what you may have felt when you're |
|
| 08:06 | down into the water a little bench that little bitch there is window grout |
|
| 08:14 | represents the the coming together of the and the slush. Now, that's |
|
| 08:22 | contrast with this surface that we saw . we saw this surface of self |
|
| 08:31 | . We don't have this devotional It's just raise up into that our |
|
| 08:39 | our plan it into the truck. we've got this transition surf unfortunately, |
|
| 08:49 | saying forceful. The big difference is lack of that erosion surface. |
|
| 08:58 | this is what we might look Look at if we were extending it |
|
| 09:02 | offshore. We're looking at in that . I'll talk more about how many |
|
| 09:10 | slash uh swelling hospital cross stratified Saints . A planer lamination swaps and then |
|
| 09:22 | that with this year trump. those are, if you like, |
|
| 09:30 | models, uh one with a bar one without a bar. In each |
|
| 09:36 | these cases. It's a it's a grain high energy are take away the |
|
| 09:46 | no, of course deposits and we're to get more players process. |
|
| 09:53 | there's something else that's going on, ? It's virtually certain the next day |
|
| 10:02 | called a ridge and model. And looks a lot like a little offshore |
|
| 10:12 | . All right, these bridges and rental, the ridge migrates onto the |
|
| 10:25 | onto swelled it onto the beach. , this is a way on this |
|
| 10:32 | is created onto the beach. Smart . So, this is a very |
|
| 10:40 | little bar ridge. Uh that is becomes a treated instead of just migrating |
|
| 10:48 | . It attaches itself offshore. And can see one right in here. |
|
| 10:54 | . Uh this offshore were ignored. longer offshore bar of the may notice |
|
| 11:02 | can see it from here. Uh are some rip channels that cut into |
|
| 11:08 | . So you see these little dark , but within you the white line |
|
| 11:13 | you know, dark space, white , dark space, no white line |
|
| 11:19 | no dark space that is Ronald. sorry, that is ridge dark space |
|
| 11:25 | between the beach, that is a and this sand is being welded |
|
| 11:32 | So it looks something like this. just a little while here's Savard |
|
| 11:40 | So what we got him is this short, my deputy services now overlaying |
|
| 11:51 | . So it's gonna look maybe something this here is bridge, maybe a |
|
| 12:00 | bit of Ronald ripple sands and Mohammed the whole thing is to recover by |
|
| 12:10 | some positive. You see here, the squatting stone deposits in bridge. |
|
| 12:19 | gets down in here. Uh I be able to Yeah, right |
|
| 12:24 | uh we get to work and let just and by saying that this migrating |
|
| 12:38 | of the region Ronald's, we get in micro title settings. And in |
|
| 12:44 | title settings, we get them in get higher highlight areas as well. |
|
| 12:51 | they're going to be if you like sub species that's washed up where you |
|
| 12:57 | this little bar, this being sandwiched swatch south costs. Now, I |
|
| 13:09 | earlier about the idea that we got coming in. You've got when set |
|
| 13:19 | uh this storm surge tests and that a pressure gradient that creates offshore |
|
| 13:33 | those currents are reflected to the light the northern hemisphere. There are mechanisms |
|
| 13:41 | the resettlement can be mm transported not beyond the surf zone, but actually |
|
| 13:49 | and beyond the are below this storm face. So there we got this |
|
| 14:02 | system of politics said onto the shelf what it results our story with process |
|
| 14:11 | are attached to the sands to be . But the transport sure now in |
|
| 14:21 | texas uh that's mainly the result of cyclones, hurricanes coming here. |
|
| 14:28 | right after hurricane Carlo, which was of the worst hurricanes to hit Galveston |
|
| 14:36 | last century. Uh Well, hes already sent uh oh, sample this |
|
| 14:45 | area. It's more data. Will Birgunj one. We have to start |
|
| 14:54 | . Yes, we re sampled but the process is able to recognize they |
|
| 15:02 | of uh yeah, hurricane. Uh this is in essence this is isolated |
|
| 15:14 | is not to say Uh six these over 60 six centimeters. So you |
|
| 15:25 | people in offshore wrong for a man this coming out of restriction. |
|
| 15:33 | I didn't sample inside here, see of there. Okay, but the |
|
| 15:41 | , the fact is you've got these grained deposits to find out below that |
|
| 15:51 | . But that's just the typical model the shelf. So he had this |
|
| 15:58 | storm awesome. So when we look these in a more general sense, |
|
| 16:04 | when you look at the storm Mhm It's going to create a current |
|
| 16:14 | see offshore decrease thickness, grain size . They're giving more closer in increasing |
|
| 16:24 | observations and converse is decreased. So we're looking at is any primary |
|
| 16:36 | occupation is more and more typically top and then the hunky post graduates get |
|
| 16:44 | with them. This descriptive more to interview clinton beyond here is actually the |
|
| 16:53 | strong play based the problem with preserving stuff. Thank you. Is |
|
| 17:01 | It's really work. So we're going see these best preserved when they enter |
|
| 17:07 | the box and not being reworked of processes. So again, this is |
|
| 17:14 | same kind of thing. Now we call these typist stocks and from now |
|
| 17:19 | , I'll try to remember to use term tempests type storm generation possible. |
|
| 17:25 | again, you see the same kind transition except let's just think of it |
|
| 17:34 | . Yes, we get less and in here because we're working now, |
|
| 17:40 | I want to talk about this transition this great enough boston here, pretty |
|
| 17:50 | to get us back into this Primary ammunitions here where we get colicky |
|
| 18:00 | strap mickey cross strata is typically in that fine grain transition of course |
|
| 18:11 | fine sand sediments are deposited from I am. Uh but it's because |
|
| 18:19 | a Hamachi bed form the it's kind great that airport actually the homeless |
|
| 18:33 | They said stations five years the bed fender in the low areas and the |
|
| 18:42 | but I hired and these things can for a few centimeters to uh immediately |
|
| 18:57 | I think you can just read this this is uh what's referred to as |
|
| 19:04 | cross strap. Now there's also a uh sway lee cross strap and it |
|
| 19:15 | similar to that just coming to see this is second to grow up. |
|
| 19:22 | you send it straight the problem make cain poster who said this is slightly |
|
| 19:33 | we're saying but and so they can term home mickey and sway lee in |
|
| 19:42 | places just as described in different parts the same setting. Having said that |
|
| 19:51 | we do sometimes it in fact I say typically fun increasingly sway lee strata |
|
| 20:00 | slightly coarser grain center, which is say in the upper portion of that |
|
| 20:05 | grading secrets. So you can see thickening here at the straw as opposed |
|
| 20:17 | yep. And it's fine to Yeah. As opposed to the hubs |
|
| 20:25 | is find the course for itself. you can actually recognize this in |
|
| 20:33 | You recognize it mainly by the thickening thinning upwards portion. Yeah, you |
|
| 20:41 | see the low angle temptations and in particular case you've got committee cross strata |
|
| 20:49 | is overlaying by five debated much So again this is the storm department |
|
| 20:55 | just that it's close enough to be to be influenced by the strong |
|
| 21:05 | So it's above storm wave base. . Now this is kind of a |
|
| 21:19 | Uh we got six right right up plane ready for this kind of idealized |
|
| 21:32 | that is kind of mimics the Balmont Sequels. In fact very. There |
|
| 21:44 | interesting comparisons between a true turn tonight they storm deposit shelf. We can |
|
| 21:57 | proximal traditional changes when you're close or water closer to the you tend to |
|
| 22:07 | out sands, they don't have but . They should follow your farm |
|
| 22:17 | You get thinner beds, you get by activated but you get more distinct |
|
| 22:24 | here, they're less amalgamated. Uh there are possible too distal trends that |
|
| 22:32 | could see in these foreign deposits They're called turbid icts ingredient organized mainly |
|
| 22:38 | they didn't know what to call is time. So one of the ways |
|
| 22:43 | visualizing this is to imagine that you offshore zam. Yeah, from we're |
|
| 22:54 | to be loaded and waves are getting and so we've got erosion and regular |
|
| 23:07 | . Yeah, you get this peak time losses. This is the net |
|
| 23:17 | set. Yeah, offshore with the postcards. Now, if you're getting |
|
| 23:26 | , we're getting to have seven coming of suspension. So typically build some |
|
| 23:34 | of sweat to my mama as these grow. It's getting more and more |
|
| 23:44 | from suspension. They'll finally, he some ripples. And but so this |
|
| 23:51 | be the package, if you due to that transition from erosion. |
|
| 23:57 | flatbed to how much the two D ripples to mud. He might look |
|
| 24:03 | like this. Where here is a we've got parallel mama ripple talk that |
|
| 24:17 | . So this is black are was suggested for this Tempesta. Everything |
|
| 24:28 | just described is okay until I come . This is a mass of massive |
|
| 24:36 | grave. He would be the A secrets or interpreter. Everything else |
|
| 24:43 | almost our business. There are some whether or not this farms under |
|
| 25:01 | Mhm. The this massachusetts clearly forms responsible density cuts or you about liquefied |
|
| 25:16 | . It's not clear that it formed storms. And so that's one of |
|
| 25:23 | things to look for in both. , it is clear that the basil |
|
| 25:29 | rode clean these large flutes. So question is to see these or |
|
| 25:37 | When you're looking at these deposits. a case where you've got a large |
|
| 25:44 | . Yeah, that's it appears this oceans. Here we go, parallel |
|
| 25:53 | in this case. Immediately. Uh almost me. Is this okay, |
|
| 26:03 | is what's typical. It's this is . Uh, you've got variety. |
|
| 26:15 | not sure why I put the These are just some examples of that |
|
| 26:21 | scoured surface coming up into the almost one cat. Oh, that |
|
| 26:34 | So again, we don't see this . We see this, this is |
|
| 26:40 | mickey capped with ripples. Oslo Yeah, against those seas, What |
|
| 26:47 | getting at is I don't think this on the shelf in response to |
|
| 26:56 | We do get this in response to density currents that are set up but |
|
| 27:05 | on the shelf. So one of big differences between storm devices to tim |
|
| 27:13 | and this is the current causes turbine . Is this mass acute? The |
|
| 27:19 | or absence? Okay, of after that's deposit is about to based |
|
| 27:27 | . So you go to estimate the of strong politics, fair weather and |
|
| 27:40 | on how much it could be completely today, but more typically we get |
|
| 27:44 | parallel to buy it to make it called lamb scrap. Yes, basically |
|
| 27:53 | to me to talk and it may at moderately Now there's been a lot |
|
| 28:03 | work done and the most recent work here looking at hyper pigment slopes. |
|
| 28:12 | we got two different kinds of mechanisms which sediment is transported past the surf |
|
| 28:21 | into deeper water. one is a generated strictly weights. The other is |
|
| 28:28 | hyper victim flow where you've got sediment is so concentrated that it actually becomes |
|
| 28:39 | that is not so much wave really related but flood related. They're the |
|
| 28:48 | concentration. Uh sediment is from a sediment coming from a river's mouth. |
|
| 28:57 | this is really going to be more associated delta. So hyper pick nine |
|
| 29:02 | not synonymous with Tempesta. I'm going try to distinguish by saying uh what |
|
| 29:09 | refer to as the two pesty is storm wave current generator. Teacher hyper |
|
| 29:18 | nine is one that is generated typically heavy load sediment river and accept it |
|
| 29:27 | transport center. Sure. And so also will give you these possible the |
|
| 29:43 | average. Yeah. one of the differences though is that here This might |
|
| 29:50 | $100 because they are driven by density and not just by a current. |
|
| 29:59 | can extend much farther offshore. So features although they have a lot in |
|
| 30:06 | with fitness possible during terminus. The even though the okay vertical sequence. |
|
| 30:21 | Mhm. So we can see a of things. But predominantly Hello |
|
| 30:29 | The parallel to ripple. Now these I don't expect you to remember except |
|
| 30:40 | say that relatively steady from unsaved. , these are different combinations of storms |
|
| 30:54 | deposits. It's not a surprise that give you different combinations of packages. |
|
| 31:03 | here you don't see the massive. even in this set you get |
|
| 31:11 | Huh? Mickey. And slowly. you're for cap Now. Yeah, |
|
| 31:21 | used the term shore face more than but not really defining it. Which |
|
| 31:26 | probably not a good thing. But of the confusions we have when you |
|
| 31:33 | at coastal sanitation is that there's two of defining short folks. Um A |
|
| 31:43 | oceanographer will define it as a zone so from the inner shelf to |
|
| 31:59 | choices and and and there often is distinct break but measured in fractions of |
|
| 32:10 | degree uh seen on the modern Unfortunately, there's no way of measuring |
|
| 32:20 | are almost no way of measuring that . Uh notice here that they played |
|
| 32:29 | breaking slowed. It is particularly short in your shelf with the base of |
|
| 32:39 | fair with we and the storm way comes out. They call the |
|
| 32:49 | Well, people use it and want . And so um I'm gonna try |
|
| 32:58 | think of it less from an oceanographer more as a set of intelligence to |
|
| 33:05 | to figure out if this is the C. C. It's just a |
|
| 33:12 | where it's good to have in your and you're thinking about apparent see both |
|
| 33:20 | on strangling. Uh we've got this eliminating. Up here. We've got |
|
| 33:27 | lot of primary setting infrastructure here. still in SAm. It will get |
|
| 33:37 | very bots, robots are or younger at some point you get into what |
|
| 33:47 | clearly something else. So there is local service here refreshing used to |
|
| 33:57 | Now everybody would agree and does this the foreshore. And so this is |
|
| 34:04 | surface. Um everybody agrees that once get into Oregon revived debate as offshore |
|
| 34:17 | . What people don't agree on is to subdivide this here. Yeah, |
|
| 34:25 | the transition from predominant zan or if lose fights insane, I'm going to |
|
| 34:40 | storm lee. Okay. And so I know this is the beginning of |
|
| 34:51 | face. I can't figure out great . And the problem is different |
|
| 35:06 | Some people draw short face basically why other people suggested fairweather way things someplace |
|
| 35:22 | here. This transition, primary sedimentary to be. So you might have |
|
| 35:37 | here here here we're in this difficult down here. I will choose to |
|
| 35:48 | this which basically defines the shortly that was predominant. And then I'm further |
|
| 36:03 | the equivalent for labels. I would up the day everybody recognizes or which |
|
| 36:20 | primary 70 sir. That is pretty going to be fair work. Uh |
|
| 36:29 | . Mr Chair. Wait because it's emotion. So the organism simply |
|
| 36:39 | Well, yeah, I would break the lower into a possible district based |
|
| 36:49 | what you get mud, which is single. So we got I'm saying |
|
| 36:58 | nations all saying while civilian innovating sam party. All right. Those are |
|
| 37:10 | definitions are used. Yeah. In sense, it doesn't really matter if |
|
| 37:19 | know ahead example having said this, think this particular way is one that |
|
| 37:29 | most favorite right now. In terms literature powder shelf. I'm gonna let |
|
| 37:38 | read this think of it as basically . It's a little bit of of |
|
| 37:48 | trump current. Uh huh influence said not amalgamated bits on the kid crust |
|
| 38:00 | coming up, amalgamated sway lee and , moderate intense foundation course your brain |
|
| 38:15 | and happier plainer across china sled across , sparse to moderate. And of |
|
| 38:24 | we know this by automation is that's not really the case actually. |
|
| 38:30 | not a problem. And basically short for sure. Okay, now using |
|
| 38:44 | definition, you can also look at central fossils. Uh face station |
|
| 38:55 | Mm Not surprised you got razors beat positive suspension fears get into the hi |
|
| 39:09 | and therefore microbiologist. And I'm sure still, yeah to fix caracas. |
|
| 39:23 | , it's pretty bad. It is it looks like Macron previously described as |
|
| 39:30 | tools and then now it's not. , so I'm going to introduce the |
|
| 39:42 | that I'm going to ask you to dwell on purpose of an exam file |
|
| 39:49 | like him. When you have a refresh one of the things that uh |
|
| 39:58 | they didn't have a trunk kid. , uh company. And so if |
|
| 40:06 | think of that transition square means the a short face Yeah. When you |
|
| 40:23 | singer, you can erode out some them. So what you end up |
|
| 40:31 | is this sequence here. Oh it is called a sharp based shortly |
|
| 40:42 | . Now what's important about it? guess this this is one thing to |
|
| 40:48 | formed during a forced depression. Now problem is it kind of looks like |
|
| 40:58 | bar. Remember the bard environment at location as well? The main distinction |
|
| 41:05 | this transition curves over down barn environment going to be right up there. |
|
| 41:14 | the lower contact. Sure, this hurt for but it's important to notice |
|
| 41:24 | because we do actually look at these to try to reconstruct. Is it |
|
| 41:29 | bard or non barred environment? Was a normal regression or forced progression? |
|
| 41:39 | this is that? All right. here we got this programming upper and |
|
| 41:50 | short I'm sure. Uh huh. that holds really pretty much the strand |
|
| 42:00 | or even away dominated health and hold a barrier solitude. I mean the |
|
| 42:08 | pattern that we're getting is going to all of the above. There are |
|
| 42:13 | differences especially with barrier off got adjacent . But if we understand this vertical |
|
| 42:25 | how forms and we're well on our to understanding how to reconstruct. Not |
|
| 42:33 | programming strand planes but also wave dominated and very well. So here's a |
|
| 42:40 | it's a program and strength uh meaning there's no look good pipe basically. |
|
| 42:48 | is there major river just idiots. case of courage. Mm They question |
|
| 42:58 | is how thick is an individual sequence how far off short. Well these |
|
| 43:09 | are like 40 km or water? , probably asian instance his package 50 |
|
| 43:19 | a made of thick. So they're blanket like uh arrangements. But The |
|
| 43:28 | is, is that one Yeah. shoot uh how complex it is |
|
| 43:38 | Well, multiple automated seems like getting . Is it a single parent? |
|
| 43:50 | here uh It's the same question before the Vanderbilts. Yeah. To what |
|
| 43:59 | is that an individual body or an body? And one thing we realized |
|
| 44:05 | that if you look at the modern of sense, they don't program too |
|
| 44:15 | off. They have totally too far and as far as the fitness 15 |
|
| 44:23 | upset. Yeah. We have some these samples that 30 m sent before |
|
| 44:31 | ready. In fact, the more we've got now. Uh huh. |
|
| 44:46 | . But this is basically Elian's great . The longer you have from grade |
|
| 44:55 | coffee and to a lesser extent sure faces can be art function on there |
|
| 45:07 | mainly we're looking at the amalgamated These complex probated. Here's what a |
|
| 45:21 | folks. It's about six m or . A operating on the pacific |
|
| 45:33 | So it's going to be Mhm. world. Seriously. Mhm. |
|
| 45:43 | that's your face is breaking up Yes, because it's being fed longshore |
|
| 45:52 | elephants. So this is one of things to think about. Under what |
|
| 45:57 | do you get? Continued pro Sandy shore loss. You need to |
|
| 46:02 | a continual source of long short And one of the easiest ways to |
|
| 46:08 | that is from a river constantly giving sentiment and re deposited followed out. |
|
| 46:17 | , so here we have a long self up only model C Word |
|
| 46:26 | is being derived from that. if we look at that Strand playing |
|
| 46:32 | there. Not here. It's actually like violence. Yeah. Do not |
|
| 46:42 | . Yes. If we were to is a geological cross section, we've |
|
| 46:52 | I mean beach ridges, which fatalities beneficial, Showing propagation of 16. |
|
| 47:01 | here. Different pathology. Okay. what we would basically say is we've |
|
| 47:11 | a two packages pro grading strand planes by hiatus and uh perhaps some |
|
| 47:35 | So this is going to be probably years old. This kind of shameless |
|
| 47:48 | chip. When we start looking pro sequences, particularly if sea levels are |
|
| 47:55 | or less the same. In in this particular example here we got |
|
| 48:01 | . For me, true. We see the program expanded long ways of |
|
| 48:10 | winery and these actually stand. So got 12 brady sand, great. |
|
| 48:25 | As 350 km long. Clearly, going to be Over seven million |
|
| 48:34 | Going to be a lot of internal in there. Is that we even |
|
| 48:38 | one of the what? What? , this is remarkably state and not |
|
| 48:48 | uncommon. We're going to see a in uh caribbean. There's going to |
|
| 48:54 | trendy. That is kind of similar that. So, so here are |
|
| 49:01 | four reservoir studies among uh finish this . Uh and if you look first |
|
| 49:08 | all the cliffs, we are we're at an area over here, we'll |
|
| 49:17 | playing. Absolutely. It isn't planet to be large areas of guard, |
|
| 49:37 | they first? Oh, strand And this might be an example what |
|
| 49:44 | for strand plane, Queen doctor Now this is one of the applications |
|
| 49:58 | uses. Why don't you better understand sequence? So when we look at |
|
| 50:12 | mhm ferocity permit abilities, what happens you get into the upper? Sure |
|
| 50:23 | Up to 60%. If and actually bad. You pretty much forget it |
|
| 50:33 | to get lunch the activation in Okay. We didn't have a lot |
|
| 50:45 | segmentation on this program pair sequence. it's gonna look something like that. |
|
| 50:55 | of these programs. This is one . See this is the way to |
|
| 51:03 | it. Uh this funny walk our . Yeah, but you see it |
|
| 51:14 | along fire forms. You see a of upper the lower this short. |
|
| 51:25 | and each of those is going to different ferocity. So uh here, |
|
| 51:37 | , that's actually more about the You've got improper grading event. It |
|
| 51:46 | there for a little while. I know if it's Shelly organisms is causing |
|
| 51:55 | . But this is is really lower poems. Talk next. The event |
|
| 52:03 | events ball. What? Okay, this is just some of the heterogeneity |
|
| 52:14 | you would expect different areas at different . So this particular one that you |
|
| 52:21 | ask uh you call it non deposition distance one. So paul Saffo settlement |
|
| 52:30 | Saman also set. So this is you might see strike section as opposed |
|
| 52:37 | dip section. And so this is they model to get a better feeling |
|
| 52:45 | how you develop uh service. I reservoir like this. And this is |
|
| 52:52 | I've shown earlier. Uh What if were imagine of genius not taking all |
|
| 53:03 | ? Uh dr Atwater Drive five Yeah here by modeling the company. |
|
| 53:18 | ah So this is James you just . Oh here you get 20 years |
|
| 53:36 | sweet. Yes, breath Yeah the is going to do no for financial |
|
| 53:59 | . So it's got a very black and and notice is a little |
|
| 54:07 | I wonder where is we just got . So model that enjoy this |
|
| 54:20 | I just haven't seen your moment in exactly having The five. This model |
|
| 54:28 | was applied to try to determine the way of having uh water sweet. |
|
| 54:38 | , the water sweepers dangerous. Uh that's the question. You create such |
|
| 54:47 | . This particular model basically showing difference how water. All right. |
|
| 54:54 | The question would preferentially channel into your into your high permanent normal sounds. |
|
| 55:09 | , they will. Uh Sure. reservoir Libya again offers shore face, |
|
| 55:16 | and miller short face. You have figure out what cool enough. Take |
|
| 55:21 | look at the purpose. Oh get that upper short fix how many |
|
| 55:29 | Well, almost 2 600. True not. There is a difference. |
|
| 55:38 | just sort of significant difference for us as well. And when you look |
|
| 55:43 | that, if you look at the shortness this is zone force. Okay |
|
| 55:53 | said so there's a huge vertical There's also a significant lateral segmentation to |
|
| 56:03 | finding coarsening up signals and again showing change. Um a lot of that |
|
| 56:18 | to do with that genesis. The upper shore face is to preserve |
|
| 56:28 | primary ferocity and permitted in part because the changing composition and the presence of |
|
| 56:39 | preferential dodging it. Cool. So another story here which is a die |
|
| 56:47 | story I'm not going to get into to tell you. Yeah, different |
|
| 56:54 | within that operating sequence can have significant in ferocity and permeability that among other |
|
| 57:03 | are reflected in their differential ga genetic , Trinidad, sweetie, pro |
|
| 57:16 | spread plane. These are little planet Peace on 12 balls that you say |
|
| 57:28 | airport. Yeah. Uh it's I but its programming over a long period |
|
| 57:38 | time. The scales here five This is like 20 km. |
|
| 57:47 | Mhm. Now when you start looking detail what you find funny little |
|
| 57:57 | Those are little this case booted aggression oppression piece are or buddies it was |
|
| 58:11 | change is great for the day. something clearly complete realized in some cases |
|
| 58:25 | completely this beds and in fact here's this particular line here which was not |
|
| 58:37 | this time. Yeah, basically sub the field. Yes. So that |
|
| 59:00 | , he is really almost completely isolates has changed the down jacket the |
|
| 59:09 | That's what you're saying. Yeah. . Yeah. So this thing is |
|
| 59:20 | like this and there's something that act maybe a little bit of training |
|
| 59:29 | Okay. You get. So in general sense is just appropriating that rich |
|
| 59:38 | it's broken up straight a graphic, little talk now why it's here. |
|
| 59:43 | a some of the structural trap segmented strata graphic. Yeah. Yeah. |
|
| 59:54 | . And a crime. Uh huh breaking on the feet. That's a |
|
| 60:04 | scale that so yeah, there's a deposition all details that's controlling how that |
|
| 60:21 | or that reservoir. Uh, this the same scale. Okay. Uh |
|
| 60:31 | strand plant 25 million years publication, or less similar period of time. |
|
| 60:46 | I'm saying here. You treated it this is how you end up. |
|
| 60:57 | you would have to model it something this would just be showing according to |
|
| 61:03 | it without Yeah. Find out for what the original during the client |
|
| 61:13 | It's kind of hard to say. uh, because there's a huge vertical |
|
| 61:18 | size. Uh, but it's probably the order a few degrees maybe 1 |
|
| 61:28 | Just guess uh, on a Okay. Looking at the Oh |
|
| 61:58 | So clearly this was a case where you need to bottle it in |
|
| 62:10 | . The last example is in Alberta looking at the older suspect here. |
|
| 62:21 | mean that baby more than they So great strength language racist. |
|
| 62:35 | Looking at this interval up in which is basically voluntary secrets from lower |
|
| 62:41 | faced short face for short action. that's going to be a member of |
|
| 62:50 | is paris Oh, general reconstruction. , she was pretty good. Great |
|
| 63:03 | that were expected to facing the reconstruction a hard you're short comment. It |
|
| 63:12 | have said it infrastructures, it shows types of bigger fishies and you can |
|
| 63:20 | at the mythologies here. Now what's about there's a couple of things and |
|
| 63:30 | a very productive fields. Yeah. when you look at a top |
|
| 63:40 | you actually see a whole series of alignment, intermediates features and trump. |
|
| 63:51 | Uh huh. Yeah, I guess is on is it? Yeah. |
|
| 64:00 | private. This is the same scale same area looked at in next |
|
| 64:15 | So you've got pro grading short life isn't producing enough. And this gets |
|
| 64:27 | little chat seemed to cut through that patriots because of what you find is |
|
| 64:39 | this sand, this Petri it is from this secret champ. So getting |
|
| 64:47 | get within that programming strand playing some due to small channels. Yeah. |
|
| 64:57 | how it's cut out. See the they're not connect pressure. So |
|
| 65:11 | Now there's another feature I'm not going get into it except say there is |
|
| 65:15 | way of looking at the well walls this cross cell which suggests of anomalies |
|
| 65:30 | right into mhm Yeah, some okay. Uh, we've got some |
|
| 65:47 | versus form and that model's murder. this is never been dominant. You |
|
| 66:01 | that fingers what you're looking at strand thinking it's water gas content that you're |
|
| 66:14 | in and out of the different coming each regions. Hey, the area |
|
| 66:31 | here that seems to be cutting off of them, these rigid ends up |
|
| 66:40 | port, some universities, non forces a crossover zone you get good ferocity |
|
| 66:48 | sure because you don't have courses. . Have said you get Yeah, |
|
| 67:02 | some, it the difference his church ports where you have micro crystalline |
|
| 67:14 | which is true. You don't have big crystal to allow easily the courts |
|
| 67:25 | form an up on or you do that position. So this is a |
|
| 67:37 | where it's not so much the presence absence of far right rim that prevents |
|
| 67:44 | court. It's the church Michael chris for just isn't a good source to |
|
| 67:52 | porch overlooks. Now what's not clear why is it that some of these |
|
| 67:57 | are championship some turn off. It to do with all the changes |
|
| 68:04 | But what is clear is that that in meteorology is a major difference between |
|
| 68:11 | and non producing the trenches. So just talks about photography, uh, |
|
| 68:20 | tribal minerals control, not genesis you the strata graphic sweet spots. And |
|
| 68:30 | can see these ourselves as well as . And what I didn't realize until |
|
| 68:37 | was that analysts Published in 2008, , that particular uh play was almost |
|
| 68:49 | , which is probably blinding this. then And around 29 they started thinking |
|
| 68:58 | how carrier have any of you heard carrier bitch? You hear it? |
|
| 69:06 | . Uh, I had still not long. The argument is that this |
|
| 69:12 | no concept back to 30's. It's resurrected in two years. You gotta |
|
| 69:20 | soon. You generated what they do they come up along the finger like |
|
| 69:30 | . There's to then be trapped in residence. Here's our conventional risk, |
|
| 69:36 | our short these caravans are the strong to test. Yeah, but it's |
|
| 69:45 | true. And they carry the hydra television. But the thing is they're |
|
| 69:55 | rich. It's just and so Beginning the 29, they begin to do |
|
| 70:05 | horizontal touch. And so now you major increase in productivity in this |
|
| 70:16 | Uh, this particular can feel sometimes the halo season because it's a hello |
|
| 70:25 | , unconventional reservoirs that is that in case down yet or at least offshore |
|
| 70:37 | provincial president. Uh, Originally it like nine billion barrels uh huh Production |
|
| 70:53 | gone from 40,400,000 barrels per day since , uh, and yet your reservoir |
|
| 71:05 | muddy sand stones, inter bedded sand on the cross strap. So those |
|
| 71:11 | storm deposits that talked about which had more permeability that ignored for conventional |
|
| 71:19 | our ending up being tremendous boon to that field, extending the foot like |
|
| 71:27 | is just, yeah, Okay, call it quits. Uh, let's |
|
| 71:33 | a 15 minute break and we'll start looking at barrier |
|
