IVZ - General Discussion, page-979

During the fsc SM did say the PA net sands were 25-30% of gross overall, not sectioned, so is the residual he talked about in M1 the light oil.

It has been stated somewhere they got pressure readings from both the PA and Upper Angwa suggesting a significant gas column. If the gas has migrated from the North and pushed out the oil, the light oil would be the residual being discussed. Filled to spill. So if the light oil has been pushed out, possibly to the flanks, there will still be wet gas at M1, possibly why they were originally thinking of drilling M2 on the Southern flank as well.
