Abstract The present work deals with the reservoir characterization and pore pressure evaluation on 13 wells (112-124, 112-119, 112-100, 112-132, 113-A-54, 113-A-21, 113-155, 113-95, 113-16,113-112, 113-124, 113- 60, BLSW-1 ST) distributed in Belayim land field which located within the eastern coast of the Gulf of Suez, Egypt where it is defined by north. This study was suggested to integrate the subsurface geologic studies, reservoir petrophysics and pore pressure evaluation are used to give a good picture on reservoir characterization for the oil accumulation of the hydrocarbon and it will help in avoiding many problems during drilling and with define the migration paths of fluids within reservoir. The study started by reviewing the geologic setting of the study area with through the previous geologic works and literature’s to shed lights on the surface geology, subsurface stratigraphy, geomorphology, structures, tectonics and geologic history. This study depends on different types of open-hole well-logs such as: resistivity (shallow and deep), porosity tools (neutron, density and sonic) and gamma-ray, to determine the petrophysical parameters and their reflections on study the reservoir characterization, So it was began by correcting the logging data of the chosen boreholes through the corerection of fluid and rock resistivity by the determination of the formation temperature. Also, the porosity tools were reduced throuth the bulk density and neutron porosity corrections. Reservoir petrophysical parameters (Total porosity, effective porosity, water saturation, reducible water saturation, Irreducible water saturation, shale volume, net sand, net growth sand, net pay, hydrocarbon II saturation, residual hydrocarbon saturation and movable hydrocarbon saturation) were calculated and represented horizontally in the form of iso-parametric maps to illustrate their areal distribution within the evaluated Formation across the area of study. Reservoir lithology presented in the form of crossplots to facilitate the qualitative interpretation, Also in the present study, the produced petrophysical results were represented, zone-wise, in the form |
