OC/Seek, another good (easy) read is the slide presentation referenced here. Page 8 mentions sediments of 700 meters thick in the Lotikipi basin. However, ERHC states the following in their most recent press release regarding Block 11A:

The full tensor gravity gradiometry (FTG) survey conducted earlier on the Block identified two separate basins, Anam and Tarach, which cover 1,600 square kilometers to the west of Block 11A and 2,500 square kilometers to east, respectively. The basins are estimated to contain up to six to seven kilometers of sediments. Based on the analogy with the Lokichar basin, burial history is sufficient to generate commercial amounts of liquid hydrocarbons.

If we are comparing apples to apples, then this is a substantial improvement (up to 8.5 - 10 times as much sediment).
