Structural and Lithostratigraphic evolution of Al Baraka Oil field, Komombo Basin, Upper Egypt as deduce from 2D seismic lines and well logging data

Twenty 2D seismic lines were interpreted with three well velocities and time-depth trace conversion to characterize thedifferent stratigraphic tops of Komombo basin and to highlight the major structural elements. Five depth structurecontour maps were constructed on the tops of Pre-Cambrian Basement, Neocomian, Aptian and Albian/Cenomaniansequences. The interpretations of depth structure contour maps show two main fault trends: NW-SE and NE to ENEdirections. The NW-SE trend is the dominant one, creating a half-graben system with two major bounding faults. Thenortheast one is downthrown to the southwest, while the southwestern bounding fault is downthrown to the northeast.The restoration of the structure patterns and sediment fill evolution in Komombo basin is attempted using the 2Dseismic lines in background, integrated with the well data (Al Baraka-1 and Komombo-3). A series of flattened profileson top of Pre-Cambrian Basement, Neocomian, Barremian, Aptian, Albian/Cenomanian, Turonian, Coniacian/Santonian,and Campanian/Maastrichtian successions supported the identification of basin dimensions during its developmentthrough the main tectonic phases
