Source Rock and Previous HitMaturationNext Hit Studies of the East African Rift

Two case studies of thermal Previous HitmaturationNext Hit and source rock analysis have been carried out to investigate similarities between petroleum systems of the East African Rift.

Key to the thermal Previous HitmaturationNext Hit of these basins is the nature and thickness of the underlying lithosphere. Several recent publications have focused on this topic and their results have been used to inform basin models of both the Lodwar Basin in Kenya and the Lake Albert Rift, Uganda. In addition, models have incorporated heatflow, temperature and vitrinite reflectance data. Burial histories are presented from the Loperot-1, Lowar Basin and a recent well in Lake Albert to illustrate the timing and extent of Previous HitmaturationTop in these basins.

Along with thermal maturity, the origin and behavior of the source rocks in these basins is an important factor in determining timing of expulsion of hydrocarbons. Both basins discussed have evidence of a working lacustrine source rock gathered from both lithological and hydrocarbon analysis. Geochemical signatures of these source rocks have also been incorporated to model generation and expulsion.
