English Abstract

The thesis investigates the role of geostatistics in reservoir modeling. Fourty five wells from the central part of the Safaniya Oil Field in Saudi Arabia were chosen for this study. Out of twelve geological time sequences, SFNC sequence was selected to be analyzed. This sequence was chosen due to its heterogeneous characteristics as it presents a challenge when building 3D geocellular models. The regional geology of the Safaniya Member in Safaniya Field was first discussed. Statistical analysis of the physical properties of SFNC Sequence such as porosity and facies based porosity was done. Such analysis helped in explaining some results in the modeling step. Spatial continuity was then modeled using variograms which is the basic tool for identifying the patterns of spatial continuity of a variable. Furthermore, Indicator variograms were calculated to provide additional flexibility to examine individual classes of the variables under study. Several three dimensional reservoir models were generated using the results obtained from the spatial analysis.
