Selim S. Shaker 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. (1973) 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 impact of geopressure compartmentalization, seal
inegrity 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:
• Geopressure transgression
and regression due compartmentalization
• The disparity between predicted
pore pressure and measured pore pressure.
• Supra and subsalt geopressure
models
• 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 AAPG, Society
of Exploration Geophysicists (SEG), Houston Geological Society (HGS),
Geophysical Society of Houston (GSH), Geological Modeling Society
of Houston (GMSH) and AADE (American Association of Drilling Engineers).
He has published several papers and articles regarding pore pressure
predictions and the impact of geological settings on subsurface geopressure
profile and risk assessments (see list of publications on this website).
