Ann: Mukuyu-2 Drilling Update, page-6

“Multiple pairs of well-developed seals and reservoir sands with effective porosities averaging 15 to 20% (based on preliminary wireline log interpretation) have been encountered in the Pebbly Arkose and Dande formations. A suite of rotary sidewall cores was acquired which will be used to calibrate these log-based porosity evaluations.
Total background gas in this hole section, above the primary targets in the Upper Angwa, is higher than those observed in Mukuyu-1 and heavier hydrocarbons (C4 and C5) have been detected, providing further evidence of an active petroleum system in the basin.”
