Ann: Mukuyu-2 Drilling Update, page-366

Great post as usual @VOGC

Just adding to this post with respect to the lack of reference to fluorescence. I calibrated the measured depths for MK-1 and MK-2 against TVD using a scaled image of the seismic and well path in autocad to get a better idea of where we’re at. It looks like the zone of interest highlighted in yesterday’s announcement at 2,582mMD for MK-2 is more likely to correspond to the shallower intervals at around 2,980mMD for MK-1. The positive from this is that this is the zone at MK-1 that was reported as being “moderately dry gas” following the mud gas data analysis. So this could potentially explain why we haven’t seen any fluorescence in the cuttings yet?

FYI - by my calc’s 2,980mMD = 3,040m TVD at MK-1. If we work on MK-2 being 400m updip in the Upper Angwa, then this would correspond to 2,640m TVD at MK-2 which on the drilling path alignment is 2,573m MD. So very close to the 2,582mMD mentioned in yesterday’s announcement.

Pure speculation on my part because we really don’t have enough info to say for sure, but I think it could mean that we’re still yet to penetrate the zones with wet gas, condensate and/or potentially light oil from MK-1. And have only just entered what might be a dry gas cap from a different source to the liquids prone source below this level in the UA (hence no mention of fluorescence yet)?
