He1, No mention of discovery, ? then they construct to paragraphs, 1st describes the Karoo with poor looking results, compared to previously described.. the 2nd paragraph is about the lakebeds with expected porosity, but 1st sentence is the Karoo, not lakebeds
The wireline logs have demonstrated a series of good quality, stacked reservoir intervals in both the Upper and Lower Karoo Group sections. In particular, the deeper Lower Karoo Group section which had not previously been drilled in the Rukwa Rift Basin and initial petrophysical analysis has demonstrated a series of well-developed good quality reservoir sands. These sands range from 2-20m thick, an average 17% porosity and 0.44 net to gross, interbedded with shale prone seals. These reservoir-seal pairs, combined with their proximity to the Basement helium source, makes this interval a very interesting primary zone.
The Upper Karoo Group section demonstrates an increased shale content, and more thinly bedded reservoir intervals. The Lake Bed Formation is dominated by sandstones and shales, with minor amounts of limestone. Initial petrophysical analysis of wireline logs over the Lake Bed Formation demonstrates good to excellent quality reservoir sands (average 24% porosity and 0.61 net to gross) interbedded with thin claystones and limestones.
Orr BB, they were right then something was cooking :) Nice to see them rewarded
