Professional Summary
(Word Format - Click to download)
I am interested in the application of seismic wave techniques to the study of sedimentary environments, focusing particularly on the delineation of petroleum reservoirs. My experience (1980–2000) in the Niger Delta and its environs led to the discovery of several oil and gas fields with combined reserves of over 2 billion barrels. I am also interested in seismic data processing and algorithm development. This interest has led me into the development of a methodology for extracting velocity ratios from converted-wave data. Since joining the Bureau, I have been working on the Oligocene Frio Formation, Gulf of Mexico, where I have identified some deep prospective slope/basin floor fans. I am currently working on a methodology for estimating interval velocities from P-wave stacked data.
