Onceover, my understanding of the regional geol is that the Triassic A sits in gently tilted fault blocks, one of which looks to be shown in the recent presos at the E. end of the Nth Akar field, extending into JPR's block and where J50 is being drilled (fault boundary at E margin). Overlying this, presumably unconformably, sits the younger stuff (Jurassic) as drape forms across the older highs. So I'd think that the Triassic would still be of similar thickness as in the Western producing part of N. Ak field, and the shale would underlie that. The 19m lower top shouldn't be a major imo, and I'm happy to hear Squidgy confirm that. O/W line is some way further down than prognosed bottom Tri-A reservoir, some tens of m's at least, since J50 is quite some m's higher updip than closest other producer to West. I have heard that carbonates can make depth conversion from seismic a bit of a challenge but I'm not strong on geophysics. That seems to have been the breakthough they made at MEO's Artemis; when they could finally tie seismic to neighbouring Wheatstone it was a bit of a revelation and they could finally see a large structure (so they believe!). They (JPR) have certainly encountered carbonates higher in the J50 well and even the Tri-A seems like it might have carbonate at top, reading between the lines.
