oa Hydrocarbon Potential of the Tertiary Rift Basins of Kenya

Studies incorporating geology and geophysics in the Tertiary Kenya rift have given new<br>insights into the potential productivity of the Neogene sediments in the Kenya rift. Since<br>Neogene period syn and Post rift siliciclastic sediments have been deposited in the basins<br>punctuated by volcanic pulses. The most important of this is the Tambach Formation which is<br>deposited on the basement, it consists of potential good arkosic sandstone reservoirs and<br>organic rich shales with TOC upto 3%. East of the Tambach Formation the Miocene<br>Ngorora lacustrine shales provide mature source rock with potential of generating<br>hydrocarbons. Intermittent volcanic eruption masks the sediments in the Kerio trough sub basin.
