SotB,

"Wellwell : he’s trying to google it. LMAO"

No, I don't need Google to check casing / tubing dimensions. Just pull a copy of the 'green book' off my bookshelf...

SotB,

"Really... you don’t know what the smallest casing size is then ......"

Yes I do. According to API, the smallest casing size is nominally 4-1/2" OD. However my understanding is that the final completions are 5-1/2" TUBING. In other words, tubing CAN be larger than casing! I don't know what size tubing the DST is run on, though. However, you can be sure that the connections will be a premium tubing thread.

I know this prbably sounds kind of nit-picking, but details are important.

SotB,

"ADUK: He means for the DST u numpty........"

Oh yeah? Since when is a DST run on CASING, OK, tubing, maybe. But let's remain technically correct, regarding terminology. Dummy.

Slipanchor,

"Rem Trader has left Scrabster, destination TOL, let's hope it's with a deck load of casings for LC."

By rights, tha casing should have been onboard, measured and drifted, ages ago. SOP.

BlooBird,

"It makes me think of the plaque that I had on wall of my office back in the 70's."

Nice one.

I never stretched to such luxuries as 'plaques' on my office walls, 'cos I moved around the world a bit, and they'd just add weight to my baggage. But I'd frequently just print something on A4 and blutac it up for others to see. One of my favorites was 'A cluttered desk is a sign of Genius'. That made people think...

A good friend (who was my Boss on one wellsite, but I didn't hold that against him) had a piece of A4 on his wall saying "It's nice to be the Lead Dog: the view's better".

Such old habits don't die, and although my 'office' at home in my flat is covered with photos, posters, and that sort of thing, the walls of my lavatory are also adorned with cartoons, newspaper clippings, and so on.

One of my favorites (strategically situated within direct view when one's seated on the throne) is a photo of Winston Churchill, cigar in hand and with a wry grin on his face, and a speech-bubble containing one of his favored aphorisms. It reads "When you're going through Hell... Keep Going!".

Despite being a bit old, I'm nevertheless too young to have known Mr Churchill when he still held political office. (Though I do recall standing by the railway when his funeral-train came past, hauled by a steam locomotive bearing his name, and a Spitfire, a Hurricane, and a Lancaster flying overhead.) But that particular phrase of his seems apposite in these weird times.

Oh medre! Forgot the cadeau!

Dear Albi,

Nice to see you back!

Here's a present (which Wellwell would do best to avoid!) A hint about what I've been up to for the last 96 hours or so.

Not sure about the horses hanging their heads bit, nor the dusty hay. But maybe this share is just down to seeds and stems again for the present...

DC,

"Getting a pressure gauge in one well will tell you nothing. You have to have gauges in two or more wells to get any indication of connectivity."

Errr... Yes.... Or maybe no. We don't know too much about these gauges. Bit given the way Hurricane tends to use 'state-of-the-art', and their close association with the Blue Army, I'm assuming whatever gets installed will be real-time transmitting to surface.

OK, WD has been P&A'd, so no gauges installed. But in the GWA context, the 'connectivity' to be proved or disproved is that between Warwick and Lincoln. We know (or are fairly sure about) no connection between GWA and GLA, due to the Brynhyld Fault.

But here's the thing. Let's imagine an alternative universe where Warwick Deep actually showed good 'pseudo porisity' via the fracture matrix. Put a gauge down there. Then drill Lincoln, put it on test, and see if there's some sort of associated pressure drop on WD. Connection (maybe!) proved. With a gauge in just one well.

In fact, this may be a clue as to why WD was drilled first. Because if it had had 'good' results, such pressure-readings might have told the company quite a bit about the nature of the aquifer 'drive', as well.

Unfortunately we're not in such an alternative universe, so now things are having to be done rather back-to-front.

"He (NP) also said that the decision to drill WD first was made after discussion with Spirit."

Thanks! I'm not imagining things.

" Remember in January they were saying Lincoln was to be drilled first so draw your own conclusions."

Idem.

" In that interview with MGW RT was waffling to avoid giving a meaningful answer."

Idem or ditto yet again. Though I think it's a bit unfair to describe Dr T as 'waffling'. Malcy's problem is that he himself waffles on bigtime, with a half-understanding of the technology, and thus tends to put words into the interviewee's mouth that they themself haven't uttered. I believe RT was simply getting himself out of the situation of being possibly misquoted. Not waffling.

Anyway, thanks for reassuring me that that particular interview wasn't a 'false memory' Maybe I'm not going senile, after all...

FS22,

"WD with hindsight was a bad idea! Need to learn from failures..."

That's an oxymoron. A contradiction of terms. As per previous posts I've scribbled here, data has been gathered. The lesson has been taught. I think HUR are smart enough to have learned something from such acquired information.

DrBB,

"Is this destined to be red day after red day until we get some news on LC??"

Beginning to seem like that, isn't it?

I had a wildly profitable poker-game last night, and was stupid enough (walking back from where I park my car) to put a fistfull of 50-euro notes into my bank account. Or maybe it wasn't stupid, 'cos I can now use that money to maybe buy some more shares.

Oh hang on, it wasn't last night. I think I got to bed at five.

Daltry,

"No one knows nothing, so stop assuming."

But logically, as a corrollary, that must surely mean that someone knows something... No?

PS I'm not from Barcelona.

johniefp (what a pseudonym!),

"My guess is it would take Lancaster to stop flowing to get us down to 20p."

And my money is firmly laid on Lancaster NOT stopping!!!!!!! :-))

Cebo,

"Daltry, if anything it is you that is making assumptions in your post - you assume that other posters assumptions mean the SP will hardly rise, then you assumed a high and low SP depending on results, you also assume that there is a lot of over confidence. - followed by an assumption that "no one knows nothing", - hopefully the BoD and the hurricane chaps know at least a little. And you advise others to "stop assuming".

REPETITION!

Go to the back of the class...

DrBB,

" what is the mechanism of the loss? Where does it go to?"

Into the 'formation', ie the fractures in the rock where the oil is. Because the 'mud' (drilling fluid, which is a viscosified Calcium Chloride brine, containing assorted other clever additives) is denser than the fluids (oil and gas in the rocks), so exerts a higher hydrostatic pressure. So 'goes downhill'!

But when it comes to DST (ie 'testing'), the borehole is put on 'negative pressure', sufficient not only to allow 'formation pressure' to allow the oil to flow 'uphill', but also to push back the drilling fluid that's previously been 'lost' into the fractures. This part of testing is what's referred to as 'cleanup'. Assuming the reservoir and fractures that have been encountered by the drillbit are sufficiently permeable to allow the oil to 'push' back the lost drilling mud.

Which evidently wasn't the case on WD, where the 'negative pressure' applied was something in the order of -1000 psi, I believe. Which is huge. Lancaster's EPS wells are happily flowing naturally with something around -20 psi 'drawdown'.

PS I hope Daltry won't get all excited by my use of the word 'drawdown'... It's a technical oilfield term.

ronok,

"Hur/Spirit were hoping to make that well a producer and so maybe had hoped to establish the oil column and get a production well in one operation. The decision was theirs to make. Although the well was a production failure maybe the tests gave them the information on the reservoir they were looking for. "

Yes.

There's been quite a bit of discussion here about WD. But unless I'm beginning to get premature Alzheimer's, I vividly recall an interview Dr T gave (maybe with Malcy), where he said that WD had been 'put forward' as first in the GWA drilling campaign by Spirit (bankrolling the thing), whereas Hurricane had originally planned differently.

Or am I imagining things?

If it's not a 'false memory', I still find it a bit intriguing. Does anyone else here recall that? Oh to have been a fly on the wall, to know what drove that decision...

Jiffy,

"am I barking up the wrong tree being a non oil knowledgeable person.?"

No. It was a perfectly reasonable question., and I hope I've gone maybe halfway to giving you a comprehensible answer. The only stupid question is the one which remains unasked.

Jiffy,

" will LC take as long to drill and test ,as WD if the depth of TD is less? "

Yes. And possibly even longer if the test results are looking good!

Jiffy,

"In other words , it all depends on the Horizontal section?"

Yes. Of course. The 'horizontal' is the part of the well drilled 'through' the 'reservoir'. Which is where the oil is, and comes out from. (Apologies for all the inverted commas, but it's the only way I can try to explain the thing.)

Everything else (ie the wellbore above the 'horizontal') is just the means of 'getting there'. If that makes any sense...

Jiffy,

"That would equate to about 75 days for LC, would that be the expected duration?"

Yes. Anticipated (approximate) duration for each GWA well is 80 days. Plus or minus.

" ie, are we drilling as deep as WD well?"

Here, I have to use some 'oil-speak'. But you've posed a straight question, so that deserves a straight reply.

After the 'buildup section' of the hole, where angle is progressively increased, the drilling assembly will start the horizontal part (ie into 'the reservoir') shallower than Warwick Deep. When measured VERTICALLY from whatever datum-point you choose. Seabed, rigfloor, average sea-surface, makes no difference really. But for reasons we don't really know about, WD was 'called short'. With the 'horizontal' only extending 736 metres or so.

Lincoln Crestal, although 'shallower', may end up being 'deeper', if that makes sense. Because in directional wells such as these, incorporating a significant horizontal section, there's another measurement that comes into play. 'MDAB', which stands for Measured Depth Along Borehole. A term coined by Schlumberger, a company which delights in inventing new acronyms, just to confuse everyone else!

OK. It's almost three in the morning, I've already done 200 motorway miles in (unexpected) rain, played poker for five hours and also watched a fabulous firework-show (which involved me having to leave the table for twenty minutes and go join the crowd on the beach: a difficult decision). So I can't really get into detail and so on and so forth about these two wells.

Suffice it to say that their 'architecture' (although physically similar) is quite different in regard to 'reservoir entry-point', and thus the geomorphology most likely to be encountered.

JayKay,

"I remember when this was a happy place!"

It still is!

Think of Eeyore, with the burst balloon and the empty honey-pot. The happiest (miserable) donkey in the world...

The spivs are spending our hard-earned crusts at Henley, Goodwood, and places like that, and pretending to be having a good time, while really they're worrying themselves to an early grave and probably an even earlier divorce.

I can wait 'til St Leger's day. Unless Cebo can come and fast-forward me to then.

Except no, dammit. I'd miss two truckraces and any number of poker games if he did that.
