Takeaways for Block 11A from the Geosoft presentation referenced by TOB:



Compare the basins shown by Geosoft above with maps from ERHC's SeeThruEquity presentation:



In both sets of maps, you can see not only the Lotikipi basin but also the apparent basin (blue-green) entering into the block from the SW. What is exciting is that southern basin seems to be in the same "valley" as the basin where Tullow struck oil (see ERHC's map on the right above; albeit that map is probably from low resolution Bouguer readings).

Below is a Geosoft map showing Euler solutions, but notice how the southern basin is more defined (right above red caret below):


(Apparent southern basin^?)

Note that the TVK-4 seismic line is shown in the first and second maps of this post, and it was used by Geosoft as the backbone to produce a model of what lies beneath the surface, combined with other data:



The TVK-4 line did not go through the deepest part of the subterranean Lotikipi basin, but rather, to the south of it. Nonetheless, this model shows the basin to be pretty thick, even at this spot. The question is, what lies beneath the rhyolites?

The primary purpose of Geosoft's presentation was to show how available data can be used to model the thickness of possible reservoir-quality sediments; they were not focusing on other aspects of petroleum exploration:


Their conclusion:
