pcpaul wrote:dspp, would be interested in your opinion, if possible, on the following points as you seem to know what you are talking about and objective:
1. A graph was shown a day or two ago showing an increasing water cut on which you commented briefly. Others have suggested that a. the increase was only in line with increasing production and therefore to be expected and b. that is is quite common for the water cut to increase on initial production ( up to several months or longer) and then to decrease as the water is cleared. It does also seem that the water cut increase is indeed in line with production increase almost exactly linearly and would this not suggest that the water is NOT water ingress from below as that would be unlikely to be so in line with production. Would you like to comment on that?
2. If there is an increasing water cut that is not so readily explained away what effect do you think that would have on the GLA story?
3. Since the RNS on Monday Spirit sources still seem quite upbeat on their GWA plans talking of "being pleased" and looking forward to going ahead as operator. What is your take on that?
4. The figures you quote for FFD funding are obviously daunting but they would be staged gradually and each stage would presumably result in significantly increased income ( assuming success but then that success should be very likely if they have accrued sufficient evidence to proceed to a FFD ?). Do you not feel that such a FFD could be self funding with enough income generated by each step to proceed to the next?
5.Do you think that the doubts generated by the GWA well results will affect the GLA FFD plans if all is well with Lancaster results?
6. Halifax seems to be on a back-burner at the moment but there have been suggestions from time to time that HUR may proceed early next year to revisit Halifax . Any thoughts?
Thanksin anticipation for any thoughts that you may be able to offer.
pcp,
Flattery will get you everywhere . As you say there are other folk here on TLF who are equally - if not more - capable than I am in assessing the situation, and I would welcome their insight as well. However here is my stab at your Qs.
1. Watercut development. The available OGA data does not allow us to discard this as a concern, nor yet to panic over it, though it must remain a perfectly valid concern until the data undeniably shows otherwise. There is an apparent upwards trend in the %watercut from 2.5% to 8% over five-months. We do not know the month-by-month flow ratios between the two wells, one of which is supposedly dry and the other of which has a watercut. It could just be that as they have been opening/closing either/both wells this has created an apparent trend. It could be that metering uncertainty plays a part in creating a false trend, just maybe. However if one takes the data and graphs a scatter plot of watercut % vs monthly oil flow rate you will see that it is fairly linear, i.e. greater watercut is associated with greater oil rates. That is what one would expect if, on aggregate over a month, both wells were flowing in a constant ratio, but one well was experiencing sufficient drawdown to lift water from source to surface and that drawdown was of course increasing as rate increased. A rate-dependent watercut is what one would typically expect if there is water being sucked in somewhere, and the question is therefore "where!". In contrast with perched water one would ordinarily expect it to be relatively constant, maybe fluctuating a bit vs drawdown depending on how it is distributed. One could postulate a zone of trapped/perched water that gets accessed at high drawdowns but ....... occams razor suggests something else. [edit: using my Mod powers I have inserted the relevant graph below.] It is a strikingly linear rate-dependent relationship. Now it could just be coincidence of the way they have managed both wells during each month, and month-by-month, but that is one heck of a coincidence ! I have yet to see anyone out there in the investment community do even this trivial analysis (I am available for hire by the big boys ....). The GOR trend is pretty flat by the way, both in time and as rate-dependent, so I am inclined to think the GOR-wobbles are more to do with metering accuracy and start-up/shut-down issues.
2. Watercut can be managed. Essentially one has to drill more wells, suck on individual wells less, and have waterhandling facilities. It means drilling capex goes up, facilities capex goes up, and opex goes up. The question to my mind in fractured reservoirs is ordinarily not whether water needs to be managed, but more when during field life does one need to manage it ? I have produced wells at much more than 90% watercut but it sure as heck makes the economics challenging at those levels. If one sucks too hard early on then there are real reservoir issues regarding stranded oil that gets bypassed, which is a major problem in fractured fields as many of the normal sub-surface approaches don't work so well. Therefore I would rather know now that this is an issue, so it can be planned for during FFD design, than to be lulled into a false sense of security and then have to retrofit the relevant reservoir strategy & wells/facilities after things are going awry.
3. In public Spirit have to be upbeat right now because they are trying to sell themselves as expensively as possible. If I was negotiating on the buy side against Spirit I would be turning up the heat against them. As far as Spirit-Hur relationships are concerned my guess is (based on the very limited public data) that Spirit will now be seeking to slow down major $$$ committments, i.e. no rushing headlong into Lincoln-Warwick FFD, at least until they know what the appetite is of their new owners. But frankly with these results I don't think anyone would rush headlong at LinWar right now, it will definitely need more appraisal wells and a good examination of the subsurface models against what has been learned in this year's drilling/producing.
4. Bootstrapping is possible, but slow and unlikely. Nevertheless it has to remain the central pathway until a suitor(s) slips a ring(s) on the finger, as to do otherwise would be to encourage buyers strike behaviour. Alternative financial mechanisms are possible to farmin/acquisition, and if I were in HUR I would be exploring them as well, likewise I would be exploring non-traditional partners. Going slow is not a good thing as it a) reduces NPV, and b) increases risk that these fields will never be fully developed vs renewable alternatives (which are coming despite what the dino-juice luddites say). However if going the bootstrapping pathway then kiss dividends goodbye for 10+ years, and LSE-AIM is not set up for that level of long term investment patience.
5. Of course. Can you tell me what Lancaster 'deeper' looks like from a reservoir perspective ? If not how can you plan a 'perfect' Lancaster FFD ? But whether that causes significant delay to Lancaster FFD decision pathway I don't know as I have not seen the relevant data. However at a programmatic level - in the Lan-success case - it might now mean that Lancaster FFD gets phased before LinWar FFD (as LinWar is definitely not a full-on success right now). The public domain data does not tell us whether such a resequencing would be advisable. It might be that a good-enough 120,000 bbl/d phase 1 on Lancaster can be reasonably be designed even without answering all the questions for flanks and depths, and that doing this is the best strategy to get the data. Without looking at the detail I am not sure. But I am so far happy that the company is asking itself these questions and doing the relevant analyses so as to be able to make these decisions as correctly as one can be.
6. Clearly Halifax and Whirlwind both need to be revisited. I think there is a drill or drop obligation on Whirlwind (correct me if I misremember) that rather forces the timeline on that (and it makes sense from a overall FFD-strategy data need perspective) so that is likely to be first-up. Re Halifax in the success case I would be pushing to go back there fast, but in the less successful case we are seeing right now it seems appropriate to concentrate the firepower on the core area to get that right.
I am as open to hearing others' views on this, as I am quite capable of missing insights if left to my own devices.
I am also pretty keen that someone(s) who knows what this is all about quizzes the company on camera in public, both about the technical issues and the commercial/investment issues. So far they have been able to control the public messaging in a way that is not as helpful as it might be. So a good red-meat interrogation would be useful, but it must be in public and by someone who knows their stuff. Doing it in private with a bunch of wet-behind-the-ears investing interns is not adequate. And nor is Malcy in any way at all, he is embarrassing.
I am by the way very worried at what I see out there on the various bulletin boards as it shows that there are too many folk with too much at risk, who really have no idea of the level of risk at play here. They could lose it all for technical E&P/O&G reasons. They could equally lose it for market 'management' reasons, and you see those games being played constantly out there.
