Enhancing Unconventional Reservoirs Characterization: First Edition. Real Case Study: Shale Gas Reservoirs, Western Desert, Egypt.

      Аннотация: The main objective of this book is to enhance unconventional reservoir characterization by developing and establishing new correlations through using a real case study of unconventional shale gas reservoir called Upper Safa formation that located in the western desert of Egypt. In addition to describing its geochemical and petrophysical reservoir rock and fluid properties more consistently through a full integration among unconventional rock parameters as permeability, porosity, tortuosity, surface roughness, adsorption, type of kerogen, level of maturity, total organic carbon content, and etc. Upper Safa formation is highly heterogeneous formation which is very close to 100% heterogeneous formation, as any unconventional shale reservoirs due to the huge variation in the permeability range from milli-Darcy ranges to nano-Darcy ranges. Thus, several conventional and unconventional rock typing methods have been applied to overcome this zonation problem, besides establishing and developing two new approaches for unconventional reservoirs rock typing.
