Industry Article: Exploring New Petrophysical Possibilities Off West Africa

Publication: Offshore Engineer
Publication Date: 08/01/2009

As the search for deepwater resources off West Africa continues, Chevron and Schlumberger have paired two rock and fluid characterization technologies to identify hydrocarbon-bearing zones in laminated reservoirs. Based on previous knowledge of the geology of turbidite deposits, and coring during a deepwater exploratory well, Chevron knew that it had potential in thin beds in an offshore West Africa play. A core showed laminations as thin as 10mm, well below the resolution of logging instruments. Armed with knowledge of the thin beds’ existence, Chevron wanted to use wireline technology that would help delineate, evaluate and assess these resources.
