HH,
I usually respect your posts, but think you've gone a bit off-tangent with your latest. Though yes, it's late at night.
"Surely that’s like using a dimmer switch on a light, when there isn’t a bulb fitted, as that would be futile."
I'd draw a different analogy.
The ESP's were no doubt used during recompletion by the PBLJ last year, just to test them.
But (to our knowledge), have not yet been turned on during EPS. So if it's a question of 'commissioning' the controls, it has to be done sometime. (See an earlier post of mine.) The timing of when it's done is neither here nor there.
Yes, Dspp's post 'point 7' does instill some doubts, once more. I'm not saying he does it deliberately, maybe he's just ultra-cautious.
But here's a hypothesis as to why they want to get the ESP's running. based on no evidence at all. But not implausible at all, I think.
We've been informed that tests have been done or are in progress, producing each well separately. We have no details whatsoever as to the results of these tests. Nevertheless, I think it can be safely assumed that during single-well 'natural' production, actual volumes produced are less than with both wells online together.
Now in the future with the EPS (talking years), there's no guarantee that problems might not occur with one or other of the wells. NOT necessarily reservoir-related. There's a lot of 'machinery' (for want of a better word) down those wells, and no guarantee that some 'breakdown' might not occur. So you want to be sure that you can continue production using just one well. should such a mishap occurs. So you want to bring an ESP online to do so.
It'll be even better once Lincoln is tied in: 'redundancy' with just two wells is OK, but only OK. Three-well redundancy es a lot better.
Or maybe (hypothesis 2), the recent 'tests' have indicated that they might want to 'bounce' production from one well to another, but I can't really dream up a reason why.
Except (hypothesis 3, following up from number 2). It could have something to do with something as mundane as pigging schedules. Shut in one well for flowline pigging, ramp up the other, meantime, just to maintain optimum output.
Why raise questions which raise doubts, when the company has already said that they'd inform if the EPS was misbehaving, and they haven't done that?
Part of Tullow's recent RNS refered to their new downsized production projections were due to unforeseen higher water-cut on one of their ('conventional') fields. It happens, and in 'conventional', once 'coning has started, it's hard to stop. In FB it's different, but anyway, the company has said our water is not from the aquifer.
People have lost money on TLW, quite possibly people also invested here. So now, mention water-cut and such people get scared. And other unscrupulous characters can easily stoke that fear, for their own personal gain.
