This board should be grateful to Bold & NH for working together to provide a textbook presentation of the Dunning-Kruger effect. Firstly, the sand used in Sandjetting is an abrasive, not a propant (Bold spelling) nor a proppant (correct spelling), that is when sand is used in fracking to prop open the fractures.
With reference to the main issue raised, that a second wireline log is not necessary - a little surprising that two posters, who claim to have extensive knowledge of drilling and engineering, haven't worked this out. You may be aware from junior-high physics that metals of different compositions and thicknesses have different rates of expansion or contraction when their temperature changes - the thermal coefficient of expansion. They will also deform differently when under strain - the coefficient of elasticity.
Imagine the first log - the logging string (of a known weight) is hanging off the end of a cable 1.5km long, in a hole where the ambient temperature is increasing on average by 35°C per km, but non-linearly, and may also change over a period of several months. You can take indicative depth measurements of promising reservoirs for future testing, but you do not know the exact actual depth from surface, because that very long cable will have both expanded and stretched. Logging-while-drilling is also performed, here the logging gear will be part of the drill string, obviously above the drill bit, all dangling from 1.5km drill pipe, which will also stretch at a different rate from the cable.
Next, Bold and NH are put in charge of Sandjetting. Since they don't know what they don't know (the Dunning-Kruger effect), they dangle the Sandjet gear on coiled tubing down to the depth they 'measured' on the first wireline log. Of course, the Sandjet gear weighs differently to the wireline gear, and the wireline cable (or drill pipe) has different coefficients of both thermal expansion and elasticity compared to the coiled tubing. Since we are looking to perforate horizons that may be less than one metre thick, there are going to be problems.
Very sensibly, we get Lonny & Moyra to supervise operations. They re-run the logging gear on the coiled tubing, weighted to match the Sandjet gear. They already know roughly where the interesting horizons are, and in which vertical order, they just need to make sure that the Sandjet gear is correctly positioned vertically using the second set of readings. These will be accurate since the same weight of equipment is run on the same suspension on the same day.
So Keith ,you are painting a grimmer financial picture by the minute, not only do we need expensive sandjet pumping spread with the proppant, abrasive, whatever, we also need an expensive wireline unit to relog as clearly the data we already spent money on ,will have changed (in your words) , then when we have got the logs correctly calibrated , we then need to tie the SJ in to the very expensive CT unit and run down to the very narrow intervals to attempt to perf. Keith , i take my hat off to your technical prowess sir, however could you please give a rough cost summary of what everything is going cost here iyo ? i mean you are referring to 3 massive distinct spreads and footprints, wirelinie unit, coiled tubing unit and sandjet pumping spread, thanks mate.
Bold, apparently you can either not read well, or cannot understand what you have read. I am sick of your
Hi keith as a slightly concerned shareholder , i am merely asking genuine questions, please don't lose the rag with me …i dread to think we may have been paying a retainer for either CT or WL whilst actually waiting for the SJ pumping spread. I am excited for the start of our ops, it is now the third time you have mentioned they may already have started, so i take that as good news. Thanks.
I have said it before, but this BB has some incredibly valuable and insightful posters (GRH, KeithOz, BRV, Wacky, MickTrick, Methodology immediately come to mind - and there are several others).
Of course, we also have our resident Klingons on the starboard bow (into every day, a little rain must fall).
I am not a technical O&G expert at all (though I know a bit about CCS/EOR technologies), so I am always very interested in, and grateful for, the incredible technical insights contributed by, especially KeithOz.
The ability to explain very technical stuff in clear English is a great gift - and KeithOz has it in buckets and spades.
So, thank you, KeithOz, for your contributions.
Have a good weekend all.
I always love to read posts from Wikipedia nerds re Dunning-Kruger.
Such posters really ought to study Milgram to remain outside of the carefully cultivated groupthink tank haha!
Come on Mr 'I've noshed off the King of Saudi Arabia' give your sheep some negatives! Turkey!
Come on Seff, you are trader fodder, nothing more.
Nige.
You’re just an utter ucking buffoon.
How things in Telford Liam.
n ****..gobble…. we all know why your here.. a total waste of space..just sit & watch sun shine..😎
As keith used to teach this as a course to his pupils,its a gift all great teachers should have,some dont,they are very correct and very technical,but being able to dumb it down so people can easily pick it up and learn is a skill in itself. thus the word teacher,one to convey knowledge to others,we can all talk very cleverly on our expert subject but weather we can teach people or not is the way we convey this across. as a example check out professor brian cox,a famous bbc tv personality,even i can understand his great explanations on particle physics, and quantum theory... and plays a mean keyboard and had a no 1 hit record with d,ream,and appeared on stage with some old guys called monty has lost his python,never heard of them,,,,. i think 1 of them owns a guest house down devon way,it got closed down as it was faulty..

Had a great preso from 3 majors on CCS arranged by some Magic Citcle chaps yesterday. Interesting stuff.
Morning IJWT,
Glad the Magic Circle chaps are on the case.
CCS on its own doesn't really stack up financially/commercially (which is all I care about, I am not a bunny- hugger at all).
But CCS allied to EOR is potentially huge. It has massive FME (Force Multiplier Effect) and brings into play so many oil fields that are otherwise non-viable or marginal (and it brings back into play many fields that were no longer commercial).
This is especially true on the Venezeulan side (on which the Trinadad fields are based because the oil there is so much less viscous (it is, basically, Marmite). So, the injection of CO2 has a massive impact on freeing this stuff up for (relatively) easy extraction.
I originally came into PRD 4 years ago because I was very interested in the CCS/EOR opportunity in Trinidad.
I remain very positive on that opportunity.
I then came to understand the VALUE of the Moroccan asset (mainly because of GRH's brilliant insights into that space) and also the potentially huge VALUE of the Irish assets (obviously, which is dependent on Irish politics - and those have never really scored highly on the rationality charts).
I think PG has assembled a great basket of assets - VALUE.
So, I think the delta (difference between ultimate VALUE and current Share Price) is potentially vast.
The gamma (time for the delta to be crystaliised into cash) is rather more difficult to get right and this ship has taken a little while to get home.
Life seldom goes exactly to plan.
I remain very firmly of the belief that PRD is an extraordinary opportunity crystallise huge VALUE.
And if I do not get Christmas cards from Little Nige, Porters and the other Klingons, that will be just fine by me.
Enjoy the weekend.
