APPLICATION OF COMPUTER PROCESSED INTERPRETATIONS ON THE WELL LOG DATA OF BELAYIM LAND, TO EVALUATE SIDRI MEMBER HYDROCARBON RESERVOIRS, GULF OF SUEZ, EGYPT.
The present study deals with a comprehensive interpretation of the available digital well-log data of Belayim Land area, using a computer program (Interactive Petrophysics) to evaluate Sidri Member. The corresponding well-log data have been processed through a sequence of graphical relations (manual interpretation) to evaluate quantitatively the different petrophysical characteristics and also computerized through the available computer software. The manual interpretation was started by subdividing the studied member (Sidri Member) into zones and the log readings were tabulated. These zones are correlated between wells, according to their remarkable changes in the log responses and their similarity. Tri-porosity (M-N) cross-plots for mineral identifications are used to detect, in general, the types of lithology. Lithologic identification is achieved through the cross-plots between ρb, Øn and Δt, to detect the matrix density (ρma) and matrix interval transit time (Δtma) for each facies. These charts show that the sandstone and shale represent the main components in Sidri Member. The mono-porosity cross-plots are constructed to determine the water saturations (Sw), formation water resistivity (Rw) and sonic, neutron and density derived porosities (Øs, Øn and Ød). Dia-porosity cross-plots were established to determine the shale volume (Vsh) and effective porosity (Øeff). All petrophysical characteristics, inferred from the previous steps, were represented vertically in the form of petrophysical data logs (PDL). The lateral variations of the petrophysical characteristics are represented in the form of iso-parametric maps (effective thickness, shale content, effective porosity and hydrocarbon saturation). It is worth-mentioning that, also the litho-saturation cross-plots illustrated from the computer processed interpretation are correlatable with the manual ones. The petrophysical characteristics of Sand3 (Sidri Member) reflect the ability of this unit to store and produce hydrocarbon. Effective porosity ranges between 12 and 24%, shale content varies from 0 and 27% and hydrocarbon saturation ranges between 75 and 92%. The petrophysical characteristics of Sand2 (Sidri Member) reflect the ability of this unit also to store and produce hydrocarbon. Effective porosity ranges between 3 and 20%, shale content varies from 0 and 52% and hydrocarbon saturation ranges between 31 and 89%. Sand 1 (Sidri Member) petrophysical characteristics reflect high ability to store and produce hydrocarbon more or less like Sand 3 unit. Effective porosity ranges between 14 and 24%, shale content varies from 0 and 19% and hydrocarbon saturation ranges between 51 and 87%. It is clear that, Sand1 and Sand3 units show better reservoir characterization than that of Sand2 unit.
