| Abstract | ||
| Tersa area lies within El Fayum concession, in the eastern part of the northern Western Desert of Egypt, to the south of Qarun lake (Fig. 1). Tersa area is one of the producing fields for Petrosilah oil Company in El Fayum concession since 2009, the field currently under development. The study area has a long history of tectonic movements, many deformation zones affect and are controlling the potentiality of the area. Structural configuration through interpretation of high resolution PSTM 3D seismic reflection data, as well as the available drilled wells, play a good role to define the different deformations. The result shows deformational zones in the area, including different sets of fault orientations. The seismic reflection data contain more information rather than the structural and depth data, each reflector print has its own characteristics on the reflected waves. In order to enhance the field productivity, a post stack inversion performed, to assess the area beyond the conventional interpretation. To apply a model-based inversion technique for the 3D seismic data, the generated initial model was processed through a number of iterations, to construct a reliable P-impedance inverted model. Although the 3D seismic data of El Fayum area is not processed for the true amplitude recovery data, the result offered a better understand for the study area and its properties distribution, which can be considered as significant indication for the future development plan for the field to increase the productivity. | ||
