Abstract: The petrophysical analyses and organic geochemistry
have been evaluated for the Jurassic Formations, Western Desert
of Egypt. The sandstones of the Khatatba Formation are
characterized by fine to coarse-grained, moderate to well sorted,
which deposited in fluvial channels and shallow-marine
environments. The measured porosity and permeability proves
the presence of good-quality reservoir rocks where maximum
values are 17{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} and 1000mD respectively with no major
diagenetic problems. The coal and shale sediments are
characterised by high total organic matter and have good to
excellent hydrocarbon generative potential. Kerogen type is
predominantly type II-III with type III kerogen. The Khatatba
source rocks are thermally mature and, at the present time, is
within the peak of oil window with measured vitrinite reflectance
values in the range of 0.81 to 1.08 Ro{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465}. Therefore, it has been
identified that the coals and organic-rich shale intervals are the
most important source rocks while the sandstones are considered
as the best good quality reservoir within the Khatatba
Formation.
