3D SEISMIC INTERPRETATION AND STRUCTURAL ANALYSIS OF SITRA-8 FIELD IN ABU GHARADIG BASIN, NORTHERN WESTERN DESERT, EGYPT

Sitra-8 Field which located in the northern Western Desert of Egypt is famous with its multi-reservoir zones. The real problem in this field is the hydrocarbon migration which cause in turn that some of the wells in the area became water bearing or even dry. The integration between the structural elements deducted from the 3D seismic analysis and the litho-facies core data, as well as well logging interpretation, gave a clear vision about the water bearing reservoirs (Salama et al., 2017). The present study proposes a significant integration between the subsurface geologic information, the interpreted 3D seismic data and the well logging data, for the purpose of delineating the major effective subsurface structures, as well as the reservoir evaluation at Sitra-8 Field area in the northern Western Desert of Egypt. This can be more helpful in any upcoming appraisal process in the future, which in turn will be reflected on the field development economically. The study area lies between latitudes 29° 44' 41'' & 29° 48' 00'' N and longitudes 27° 56' 27'' & 28° 00' 00'' E. It covers an area about 35 km2. The authors in the current study tracked Abu Roash-C Member reservoir for the same problem and tried to introduce a suitable tool for addressing the hydrocarbon leaking problem. The study was a worthy challenge to find new promising areas; when it comes to the hydrocarbon exploration or development. The authors based on analyzing the petroleum system of the investigated area are recommending future drilling for development in the northeastern part of that area.
