dspp,
" May I suggest you look at the watercut vs monthly flow rate SCATTER plot I posted on TLF along with the accompanying notes in various posts. Not the month-to-month calendar trend, but the x-y scatter plot. Then you will probably understand the concern, and the (so far) three hypotheses that I have been able to propose. "
I have been following your posts on TLF, and thank you for all the work you've obviously been putting in. However (yup, you were waiting for that word, weren't you? ;-) ), although I can't disagree with your 'scatter chart', I still contend that it contains just too few data-points (5 in all) to justify any 'concerns' relating to oil/water ratio. Also, the data upon which you base it (that from the OGA), doesn't justify drawing any particular conclusions whatsoever. Because your 'base graph' (OGA) is drawn showing average bbl/day on a monthly basis. And a calendar month is purely a man-made and convenient reference point, nothing more nor less. How about if the OGA graph had been based on time intervals mid-month to mid-month, instead. I'll bet my shirt that the figures on which it was based would be different. Or how about 45-day intervals, instead. Different again.
Furthermore, the most recent data point indicating 8% 'cut' is the last one based on the September figures, gathered just two and a half weeks after getting both flowlines active again.
Allow me to run a completely (maybe) ridiculous idea past you. An imaginary scenario, hope it makes you laugh. What if in the process of getting both flowlines online, one had had to be displaced to water? On opening that flowline back up, the water would have gone through the production train's metering systems, and by rough reckoning, 2.5 km of 5" flowline contains about 150 bbl fluid. Subtract that from the water produced that month, and we're back to 7%! OK, I know it sounds daft, but on what are the figures provided for total 'fluids through the system' based? The figures recorded on the meters, or 'doctored' figures? Surely not the latter.
Also, compare the positions of the September and July data-points on your chart, relative to the 'mean' straight line you've drawn. The July water percentage is further below the line than the September one is above it! What does that mean? That we should choke back and run the wells at the rate they were flowing at in July, just to get a lower watercut ratio? Of course not, because it'd mean less oil going to market and making money, and anyway, 8% is still way withing 'guidance', and can be easily coped with by the AM.
I am not suggesting that the OGA data should not be ignored. I was very glad to see it, myself. But other than the Oil / water /gas figures it tells us, it cannot be used as a method for trying to gauge whether the EPS is going according to plan, or a reason to class it a 'failed experiment' kept secret from us (dishonestly) by the company, throw our arms in the air, and sell all our shares...
