| The Arab-D carbonates represent the most prolific oil-producing interval in the world. Yet the reservoir architecture remains problematic and with the exception of rare horizontal borehole or high-resolution 3-D seismic data, information is largely missing about lateral stratigraphic relationships. Spatial distribution of porosity and permeability and more specifically their extreme values are critical factors in the performance of the reservoir. Therefore, the main objective of this study is to develop a comprehensive 3-D quantitative geologic model of this reservoir.; The study extensively investigated the spatial distribution of lithology, porosity, and permeability of the reservoir in the study area by integrating wireline log data and 3D seismic data. The study provided detailed analyses of the physical interaction among facies distribution, stratigraphy, porosity and resultant permeability. A multidisciplinary approach was adopted by this study through the integration of various techniques. Seismic inversion, seismic facies modeling, geostatistics and multiattribute transforms and neural network techniques were utilized in order to achieve better accuracy. |
