(Continued)
Just a few days ago in another post, I wrote about my suspicion that although the company has been saying that 'production' from the two wells is in the main from just 40 metres or so of their horizontal, the 'heel section', my belief is that 7z's 'water zone' lies beyond that. I still believe that to be the case. It's in fact the only logical reason for water having been seen (and incoming) from 7z, but not 6.
Pressure-transmission between the two wells has been described as 'instantaneous'. OK, fine. However transmission of pressure doesn't mean that fluids are actually flowing between the two wells over those 350 metres. In the same way that when someone claps their hands a hundred yards away, although you hear the sound, it doesn't mean the air molecules between their palms have actually travelled to you. Think of it like a wave in a pond.
Anyway. Back to the RNS. What does shutting-in 7z mean, especially looking forward?
Now, I start scratching my head a bit, because as Johnpwh said, Dr T is the 'expert', certainly not Adoubleuk. Plus Adoubleuk has no access to hard data, just the same stuff as the rest of you, through company publications, RNS, and so on.
Shutting-in 7z will allow things to 'stabilize' a bit. I've a nasty suspicion that the decision was taken because a slight increase in water-cut was beginning to be seen from 6, as well. In other words, actual 'fluid transfer' across the 350 metres between the two wells. However, will such a 'transfer' (if it's happening) continue with 7z shut in? My suspicion is no, or at least not at the same rate, for simple friction-loss reasons.
Or at least, I certainly hope not, otherwise we may be in real trouble.
So instead, they're going to 'ramp up' 6. Which will be interesting, and fun !
But there's the bogeyman. This dam CV19 thing which has caused the commissioning of the ESP's to be delayed due to 'minimum manning' requirements. Had the pumps been deployable, it might be a whole different story. Contrary to what Johnpwh said, it's not just a question of 'choke sizes'. or at least, that's a point of disagreement between us. But until the ESP's can be brought online, the EPS is to my mind a bit like playing Monopoly without any Hotels being available in the box.
Goddam CV19. Spoilt all our fun. Without that I'd be heading down the road to Royan this evening to play poker, which used to pay my rent. But I can't.
Nevertheless, with things 'easing', there are seven people coming to play poker at my place on Sunday! And although we know each other and are of 'friendly' terms, I still aim to take some money off 'em. Not enough for rent, but maybe enough for my electricity bill.
Which is why I've topped-up pretty much instantaneously today. Choppy seas, but the voyage continues.
PS People comparing this to SXX are just stupid.
