Abstract
The main purpose of this study is evaluating East Bahariya Concession to build 3D structure model, especially for Amana Field by studying subsurface geologic structural features and hydrocarbon trapping of the area based on 3D seismic cube through picking and identifying the major structural elements and horizon packages on seismic sections including interested reservoir markers (Bahariya Formation and Abu Roash “G” Member) which are considered the main potential reservoirs in the study field. To achieve this objective, the study started by explaining the geologic setting of the area, including the stratigraphic sequence and dominating structures through a review for the pervious geological studies. Then, detailed 3D seismic data interpretation was carried out and integrated with data of 4 wells to determine the structural geometry of interested reservoirs and develop a structure model of the reservoir rocks in the study area using Petrel® Schulmberger Software to provide accurate information about the subsurface structural geometry and fault pattern of the study area.
3D seismic data interpretation has started by fault pattern interpretation in order to detect the subsurface structural features using conventional and unconventional seismic interpretation (coherence attributes) methods to delineate the optimum interpretation of seismic, highight the main faulting pattern and to enhance seismic reflector continuity. Then horizon interpretation process has been achieved including identification of the interested reservoirs markers. Seismic data interpretation has been used for constructing two-way time and depth structure maps on the tops of Khoman, Abu Roash “A”, Abu Roash “G” and Bahariya seismic horizons to show some closures, major trends and subsurface structures in the area. Finally, 3D structure model has been built and confirms the interpreted structure from seismic data interpretation.
The present geophysical and geological study discloses that the structural geology of the area was affected by tectonic deformation system caused a regional uplift. The principle structure of the area is represented by three-way dip closure of NW-SE normal faults that was very obvious on seismic sections, structure maps and the 3D model.
