Ozzy,
You said:-
'you know that there are no guarantees in any complex procedures' - I think I've been pointing that out for many years - but posters still persist in claiming things UKOG 'expect' to happen will definitely happen.
that was in reply to a post from Adrian where despite 'no guarantee's, and no mention of increased production from UKOG he said there would be.
As for success/failure without full information it's impossible to accurately say, even then I doubt UKOG know absolutely. Will it completely fail - unlikely but possible (10%?) which includes a disasterous rapid return of water to HH-1 from HH-2z through fractures and or the high porosity / permeability zone they were so happy to have kept the horizontal located within - of course, like the water ingress from presumably nearby fractures to HH-1 which took a few months, this wouldn't happen immediately - if it's withing the sweet spot it may herald a brief period of sweeping oil towards HH-1 - which is what would be hoped for but as this doesn't appear to be a 'rising' water leg it becomes complicated.
As for degrees of success up to massively improving production at HH-1 - between 10% to maybe even 80%. But injection is only part of the story. Based on the OGA data the water production increases far more quickly
than oil - even within the tight range of production (averages deviating by only a few bbls of oil a day) that UKOG have maintained. This suggests that a linear increas would mean by 150bopd the water would also be about 150bwpd - whilst oil has increased by ca 50bopd, water increased by about 100bwpd. Then there's gas production - which needs controlling by maintaining reservoir pressure.
But although this isn't guesswork there's a lot of variables and little information and I keep coming back to UKOG's statement which I'm afraid is best repeated in full:-
"We look forward to the conversion of HH-2z into a water injector in the Spring and to the resultant increase in net revenue from the reduction in water handling costs. The significant 66% reduction in general field operating costs over the past year also allows the field to take full advantage of the current strengthening oil price.
Once the injector is in place, to boost production and net revenues, we plan two more production infill wells, one in each of the Portland and Kimmeridge oil pools. These will be scheduled after the potentially transformational initial appraisal drilling campaign at the Company's Turkey Basur-Resan oil discovery is completed, later in the year."
This is from the HH Update 15 Jan 2021, and has been repeated elsewhere since then - saving water disposal costs for HH-1 (good news) but 'boosting' production only with further wells some time in the future after Turkey.
This seems to suggest UKOG don't expect oil production will increase significantly, which is why when Adrian says HH-1 will be producing 300bopd post injection I respond
