Lamu Basin - Kenya - 2008

KYA Deepwater 2D

Deep water 2D seismic survey across the Lamu Basin, offshore Kenya
Website Map for Survey Kenya
This first major survey in the deepwater area of the Lamu Basin provides high quality seismic imaging in a frontier area. It covers around 27 000 sq. km, in water depths up to 3 300 m, and was designed to highlight untested prospectivity.
Discovery wells in the south of the basin prove the existence of a mature source rock and reservoir horizons. The best potential source rocks are in the Eocene Pate Limestone and Eocene-Oligocene Kipini shales. Reservoir horizons are in Upper Cretaceous sandstones.
