Ann: Total Depth Reached with Additional Zones of Elevated Gas, page-264

Looks to me as if the WHOLE of the 8 1/2" hole section might be in-play INCLUDING:

Pebbly Arkose 2.5Tcf +102mmbbls

Upper Angwa 4.1 Tcf +182mmbbls

Lower Angwa 2.6Tcf +120mmbbls

From10th November RNS:
Potential zones of interest in Pebbly Arkose (& Forest) also display elevated LWD resistivity.

But mud gas composition data was NOT available from depths shallower than 2820metres through Dande, Forest & "Majority" of Pebbly Arkose horizons due to multiple gas chromatography systems failures.

ALL zones of interest will be comprehensively evaluated through the planned wireline logging programme.

So that's (possibly !!) 9.2Tcf +404mmbbls "in-play" from the 8 1/2" ?
