tnm,
that's understandable, i've been tempted to add more at this level too. we'll just have to find out what is causing that pressure down there and the return to original pressure. there is a possibility that the solution gas has recharged too as well as the oil. could there also be water drive, no water was logged in the wells so the water is currently a mystery. even on to-13 it was just oil shows and the most down dip well to date. could there be water on down the flanks close to the two injection wells, perhaps, we may find that out at a later date. because the reservoir is very over pressure there could be both drive mechanisms ongoing, both solution gas and water drive. hopefully we'll get more info from the testing and the ffd drilling. there's plenty of infill and stepout space left yet, south eastern flank of the field looks pretty sp****. i'd like to see if they mention the gor with the flow test results. something down there has recharged the pressure.
nige,
the company has already suggested to-13 and to-14 are connected, therefore likely to be on a similar pressure regime. also 120m of oil shows in to-13 and 80m of oil shows in t-14. we don't yet know the downhole or flowing pressure of these wells. to-14 closest offset well to to-4 (12580bopd), so hopefully that one will flow quite well even if it doesn't meet to-4 rates (it may do but not counting on it). to-13 is around 1.4km away so reservoir quality may change even if its still highly fractured. my guess at the moment would be that to-14 on the crest is likely to flow better than to-13, even though to-13 was first described as a cornerstone well and has a larger oil column. reason being, production history of the field, to-14 positioning. could to-13 still outperform the other wells, it may do, its the most down dip well on the field. increased depth normally means increased pressure. my current view is with modern logging and completion these wells should outperform the 1960's well given the information from the drilling to date. we'll know either way very soon. the company now describing themselves as an exploration and production company is the most telling statement yet.
