Abstract
Eleven 2D migrated Seismic reflection sections and well logs of eight exploratory wells are used to evaluate the hydrocarbon potentiality and the entrapping styles within one of the hydrocarbon productive oil fields in the Western Desert; The Razzak field. The field lies in the northern part of the Egyptian Western Desert, NE of the Qattara Depression between latitudes, 30(R@ (B25? & 30(R@ (B35? N and longitudes 28(R@ (B24? & 28(R@ (B36? E. It is bounded from the eastern side by the Alamein and Yidma fields and from the west by the Aghar field. The Razzak oil field is operated by the Gulf of Suez Petroleum Company (GUPCO) that is a joint venture company between the Egyptian General Petroleum Corporation (EGPC) and the British American Oil Company (BPAMOCO). This field occupies three exploration blocks of the north Western Desert exploration acreages. The structural interpretation of the seismic data helped in the construction of TWT contour maps on the tops of the Apollonia Formation, the Abu Roash ?G? member, the Alamein Dolomite member, and the Masajid Formation. A comprehensive analytical formation evaluation program has been applied on the available well logs utilizing an Interactive Petrophysics software (IP), to identify the lithological constituents, petrophysical and fluid saturation parameters of the Abu Roash ?G? member, the Bahariya Formation and the Alamein Dolomite member, as prospective reservoirs in the field. Integration of the structural characteristics detected from interpretation of the seismic data and the petrophysical parameters deduced from interpretation of the well logs are helpful in outlining the reservoir characterizations, hydrocarbon potentialities and trapping styles within the studied field. The study emphasis the following recommendations: 1. More attention should be given to the studied formations by applying the newly developed technology, particularly (4D) seismic survey, AVO ?Amplitude Variation with Offset? and bright spots. These top technologies provide powerful tools for understanding the reservoir characterization, the complex structures in the subsurface and in reducing risk of drilling dry holes. 2. Further exploratory wells are recommended for drilling in this part of the Western Desert that have proved to be of a high hydrocarbon potential area, which is rich in source, reservoir and seal rocks. This, in addition, to the presence of structural and stratigraphic traps favorable for
