摘要
Using the available seismic data, this study aimed at the evaluation of the prospectivity and hydrocarbon potentialities to the deep formations structure of the Asala-Samra area.The Asala-Samra area is located in the Western Desert of Egypt, south of the Northeast Abu Gharadig Concession and west of Qarun oil field. The 3D-Seismic data covers about (56 km(2)) which called East Bahariya Area. The acquisition of high quality 3D seismic data integrated with the well data resulted in accurate delineation of the structure traps and the different elements of the petroleum system in the study area. The interpretation results of the high quality seismic data contributed to in the understanding of the tectonic history of the study area. Evidences for the presence of Jurassic-Early Cretaceous rifting, Late Cretaceous rifling, Late Cretaceous-Early Tertiary inversion, and Late Tertiary (Miocene) rifting tectonics were documented from the interpretation of the seismic data. The main productive reservoirs of the study area are Abo Roash "G" member and Upper part of Bahariya Formation. This research focused on the deeper formations and structures from Early Cretaceous and Late Jurassic which didn't test as HC trap yet and aims to add new undiscovered zones. Many seismic leads of Early Cretaceous and Late Jurassic were recognized from interpreted seismic data. Most of them are four way dip closure to avoid the side sealing problem. The source rocks are working in the eastern part of the Abu Gharadig Basin. The regional top seals for the different reservoirs in the study area were evaluated through isopach maps. A reservoir evaluation of the Alam Elbueib and Safa sands has been also attempted.
