Abstract
The top sequence of the Cambro-Ordovician Gargaf Group in NW of Concession 6 is interpreted. Time, velocity, and depth contour maps were constructed.
Two prospects were mapped in the studied area; one is well defined with many gas-producing wells located to the east, the other, which was newly defined, is located to the west of the area. The second prospect appears to be an attractive one, but needs to be confirmed by further seismic survey.
The isopach map of the Bahi Formation shows a good coincidence between the structural closure and the Cretaceous palaeohigh structure of the area. Similar coincidence exists between produced well locations and the palaeohigh.
