Selim S. Shaker, Ph.D is Director of and Consulting Geologist for Geopressure Analysis Services Inc. (G.A.S). He received a B.Sc. (honor) in Applied Geology, M.Sc and Ph.D.in Geology from Assiut University, Egypt. He also received a diploma in Hydrogeology (1975) from Prague University (UNESCO). With over 30 years in the oil industry, he started his career in Egypt as well-site, stratigrapher and structural geologist. During his 20 years of domestic service with Phillips Petroleum, his main function as Exploration Geologist was prospects generation in offshore the Gulf of Mexico and onshore Coastal areas. He discovered and developed more than 200 MMBOE, and also evaluated several exploration projects in NW Australia, Libya, Algeria, N. Sea and China. After retiring from Phillips in the year 2000, Dr. Shaker established G.A.S. to focus on evaluating the implication of geopressure compartmentalization, seal integrity and salt interaction on leads and prospects on the Shelf and Deep Water of the Gulf of Mexico. Pre and Post drilling risk assessment of a prospect is his specialty. As a pioneering geoscientist, his recent domain is building the geological foundation for pore pressure prediction. He has been the first to recognize: -Supra and subsalt geopressure models -Geopressure transgression and regression due compartmentalization -The disparity between predicted pore pressure and measured pore pressure. -Pitfalls of converting PP from psi to ppg mwe in reservoir rocks -The qualification of centroid phenomenon in the subsurface geopressure. -His new method of NCT (normal compaction trend) calculation will eliminate a serious mistakes and mishandling of pore pressure prediction modeling. He is an active member of American Association of Petroleum Geologists (AAPG), Society of Exploration Geophysicists (SEG), Houston Geological Society (HGS), Geophysical Society of Houston (GSH), Geological Modeling Society of Houston (GMSH) and American Association of Drilling Engineers (AADE).

From 1994-1996, he studied planetary geology as a NASA-funded postdoctoral fellow at Southern Methodist University. In 1996, he returned to his alma mater, now UL-Lafayette, where he was awarded in 1997 the Hensarling-Chapman Endowed Professorship in Geology. In 2001, he left academia for industry consulting and teaching. He’s been the LGS Editor since 2002. He’s received many grants and contracts, presented numerous talks, and published various papers on a diversity of geoscience topics. As a USL undergraduate he developed a 4D quantitative well bore guidance theory, including the concept of positive versus negative thickness (sign indicating direction of drilling section), that predated availability of key real-time data. As an independent consultant for Baker Hughes for the last three plus years, it’s been particularly exciting to see just how far the reality of LWD technology has since advanced.
