adoubleuk,
"you're obviously tech-minded like myself"
My oil and gas knowledge ends with my degree. Most other knowledge comes from working in project management. As with CaptainSwag, I do not have real world experience in the oil and gas sector so i'm happy to be corrected so I can learn.
""ESPs help control the water cut"
No they don't"
As CaptainSwag has said, the ESPs "control" or tries to maintain the watercut, not reduce. The watercut will increase (in conventional oil and gas systems) as more and more barrels are produced and the well draws from the aquifer, but at a much more controllable and manageable rate.
"The ESP's were installed on well 6 two years ago"
Ignoring the interference and focusing on just one well, there is no need for ESPs if the well can produce a decent PI (which HUR's well does) with little water cut. Two years ago, water cut from well 6 wasn't an issue. From the recent RNS, HUR have told us that the water cut in this well has increased from 8 to 11%. Going forwards, it makes sense to me ESPs are required to "control" this watercut.
"Personally I can see an advantage is running well 7z on ESP while retaining 6 on natural flow, as a means of artifically 'balancing' their pressure regimes and preventing 7z's higher water-cut from affecting and influencing 6."
I think having ESPs on both the wells provide you the ability to control the pressure at both wells. Almost as if the ability to control where the water should flow to in the reservoir.
A natural well without an ESP will just be "forced" production. E.g. the force being the HUGE pressure difference between atmospheric and the reservoir and thus, oil is forced out. In a 0% watercut situation, this is great since there's no limit to production (and no expenses of running pumps!).
In this case however, as the watercut is rising, a more controllable option with the ESPs works better IMO.
"But don't expect them to be some magic wand to reduce the water-cut in the near future. In fact, if 7z is put on preferential flow, percentage overall water-cut may increase"
Definitely not. Although it's quite hard to predict when the concept is FB.
I agree that it is more likely than not that the watercut will increase. But i'd like to think that the increase is more controllable (with ESPs as mentioned above).
@CaptainSwag
100% agree that RT didn't live in the real world and wanted data for his paper. I also noticed that he had no project management experience in comparison to the other directors.
Definitely good to have RT with the team for his expertise, but with more of a corporate head
Slift.
