I could tell you more about horizontal drilling, but I can’t be bothered right now. In the mean time before I bother, you could probably use google a bit. It’s actually quite amazing what the precision is with the right equipment packages and decent directional drillers on your team. As with most things you get what you pay for, and going to the extremes is something where the cost benefit usually makes a lot more sense offshore than onshore. But if you want to see a good land application, and with some very cool passive water reducing production “valves”, read up on what Petrotal is doing from a single well pad with their high water cut field in Peru. Physics - it’s the law, and can do wonderful things for you if you understand it and apply it correctly.
You must have mistyped, Cascadura production wells will not be 2023 or 2024, that is why they are doing the big EIA, they can get smacking on that right away. You are thinking Royston, but that EIA will be started as Royston is hit now they know what needs to be done, so your timeline is overly pessimistic, Royston will roll fast once we get confirmation of a hit, hopefully a grand slam hit. Trinidad is desperate for the gas …… and we have it, onshore, ready to roll.
I had a dream last night that Spawny and Buffy got married and rode off into the sunset never to be heard from again …….
Then I woke up and read the forum.
I think I Rendal something from the issues with Shell that they wanted commitment for more gas from Coho, so if they are dropping the Deep well in the legalt now, it’s probably to smash out these 4 commitment wells ASAP, and then move the Star Valley Rig over to Coho to pop a couple more production wells in there.
This makes sense, would give Shell what they want, which is higher volumes, and would get to market quickly. NGC would the have to pay for more pipelines, and heritage would have to pay up some cash for their 20%.
10 bar or 30 bar or even 100 bar due to the ocean doesn’t matter was the point, so you didn’t get the physics, but that’s okay.
Obviously comingling zones with high differential pressures doesn’t work, they would have to be isolated. Not that this is a problem for TXP anyways, cause we don’t need to go through the hassle and expense to do it, but it is possible.
This is just basis physics, but it hjelps to know how to apply it. I have worked in the oil and gas business for 25 years, have engineering school, and also a drilling school, but never worked specifically with drilling. Worked mostly with subsurface geophysical related data and offshore surveys. Also done a fair bit of subsea construction, and am a supplier to subsea construction and well intervention companies.
It really irritates me when people make stuff up and then talk about it like it’s true and they really know what they are talking about. A half ****ed idea is maybe best left unsaid.
They were not expecting to find so much pressure at Cascadura, but it is not over pressured. I bet things got a bit exciting at times on the rig ……. But they kept it all under control, and are aware of the potential now, so that’s a very very good place to be.
The gas pressure is in the pores of the rock, and probably not supporting it that much. Chalk on the other hand like Ekofisk will subside when oil (or gas) is removed and why they had to jack up Ekofisk platforms by cutting legs and well connections. Google it, massive project, quite interesting.
The depth however, does enable that high gas pressure to be contained. If it were shallow, that high pressure would blow the top off so to speak ….. 280 bar close to 1 bar, or 30 bar, is quite a high delta, a bit higher than a standard SCUBA tank.
Just so it’s said, a high pressure well will be ranging over 10,000 psi, we have 4,000 which is a lot, but it’s not the highest pressure the world has ever seen. There are classifications up to 40.000 psi, but this has never happened, or is extremely extremely rare. 1.5% or wells world wide are HPHT, so over 10.000 psi. Google HPHT.
Your assumptions about pressures offshore in different stratigraphic zones are false. They vary to the same degree that they do on land. Basic physics.
With 100m of water you have 10 bar pressure on the seabed. In 300m of water, you have 30 bar. On land, you have 1 bar. Cascadura high pressure gas is about 280 bar.
Why in the world would a 9 bar or 29 bar or whatever else differential on the surface have anything do do with the pressures that are in the reservoirs of similar depths thousands of meters under overburden Scott22 ?
Answer is, they don’t. You’re just making things up.
It is not super complicated to produce from two separate zones in the same well, but it does cost more, and requires that the casing where the packers and production tubing are run are large enough in diameter to accommodate the double completion. With the low cost and desired simplicity of operations we have on land in Trinidad, it is cheaper and more efficient to just produce one zone at a time from different wells. You can always move up to higher zones also once you decide you will not produce from a lower zone anymore.
During testing, you always start at the bottom, pack off and move up. TXP sets permanent plugs moving up, and as such, it is not possible to go back down and produce from a lower tested zone once a zone above it has been tested. You could always mill a permanent plug in case someone wants to argue this, but this is not something you really want to do, or would plan to do.
We’re on land, all is so easy to drill, it’s super cheap to drill, we take the easy road and make the highest profit. Offshore, you have a limited number of slots, and limited life of production assets before it becomes to expensive to maintain the equipment and therefore may spend more cash upfront on multiple completion designs and solutions.
Google multiple zone completions if you want to understand more about it.
The first Cascadura well design is simply not large enough in diameter to produce what the reservoir is capable of maxing out. They increased the casing size (started with a bigger initial hole) at Cascadura Deep, which carries into every other casing and finally production tubing, meaning the well is properly sized for the massive production possible. All further wells at Cascadura will have higher production capacity than Cascadura ST1.
Offshore, exploration wells are rarely if ever used for production. They are drilled very thin to go fast ad save money. They are plugged and abandoned, and the production wells are designed and drilled to meet the needs but exceed on time and cost (rig time being a major cost).
Anyone smell gas yet? ??????
Well, then you should do a better job of explaining how big it is then Paul ……. WTF
And why do we have to wait until year end for a reserves report, we could very easily have commissioned one after Casc Deep was finished and they saw that there were issues with Chinook. This could be done and usedvanlig for lending facilities, snare holder satisfaction, etc. Again ….. WTF
Maybe we should stop the management buying small holdings every month which favours a low share price longer, and rather give them options with higher strikes and very short expiration dates. The best way for us to defend an attempted buy out is to keep the price high.
That’s what I already said, STFU (don’t be a snitch), and talk about TXP.
I don’t like Linton either, but I would never reduce myself to such a level as snitching and reporting people, for anything.
We won’t be paying for the pipeline construction, and will get reimbursed for the pipe and related engineering costs for the Coho pipeline that TXP has already funded. So, these funds will be added to our cash to help fund Cascadura facilities.
McBride, your banter is at a child’s level. Doesn’t even warrant a response. Just stop running to mommy or teacher, and a grow a pair. Sorry you were picked on so much in school, but I wasn’t your bully.
Why does everyone feel the ned report people? Adult people reporting other people like they were small children in elementary school. Grow up you ****ing pussies! No one likes a tattle tale, so stop being so offended for every little thing you don’t like and running to mommy.
Linton is an absolute Tool, we all agree on that. If he runs his mouth, come back with something better or STFU
A bunch of shallow wells at Chinook and a short pipe to Cascadura should be commercial. Area is quite extensive. Also remember we have a dry limited formation surface area in this well. Further wells will likely be horizontal, vastly increase production surface area.
But this isn’t really what Chinook is about, it’s about the oil in the massive updip to the east.
A bit of gas production will pay for this Chinook 1 well over time, and so this is good, it’s not a total write off at all, but will take care of itself and more. Further wells for the Cruse gas will be shallow and cheap, and likely horizontal with significantly higher production surface area which will allow for higher flow rates.
Well, do remember when you were little having rubber helium balloons, and then foil helium balloons? Which one held the helium longer .....
It’s crazy to think of all the balloons in the world over decades and people inhaling helium just to talk funny and laugh, and then suddenly, it looks like there’s a helium supply issue, and it’s really important for a lot of different really really important stuff, and it’s kind of difficult to find and extract, and no one ever realized this (or maybe they did, but didn’t speak up), and we just wasted incredible quantities for ****s and giggles, for DECADES. Go humans, we’re awesome!
Oh do tell us how many shares you have shorted and tell us on the day or days when you close it so we can see the volume.
Also, what was your entry point on the short?
A few locals and particularly one stand above the rest. Otherwise there are some people on the operations side that need to do things a bit differently. Never said anything about the geo side of things.
One can also draw large question marks concerning the efficiency of local suppliers, which is why giving them some competition might up their game a bit. There are other alternatives in the world, and we’re using one soon.
