Prospectivity of Hydrocarbon of Zakiganj Area, Sylhet, Bangladesh
Abstract: The southern part of Zakiganj prospect is one of the remaining undrilled potential structure and suitable for hydrocarbon entrapment in Surma Basin. The fold belt is characterized by series of meridional to submeridional folds and extends into the Indian territory of Assam, Tripura, and Mizoram to the east. Considering Tripura and Assam states of India, now exploration targets would be along nose and flanks of major plunging anticlines where prospects are segmented by transverse fault. The surface geology of Zakiganj is covered by young gravelly sand, alluvial silt and clay. Geology of Fenchuganj gas field is similar to that of other fields situated in Surma Basin and reservoirs are covered with Miocene sediments. In Zakiganj prospect the source rock is probably Jenum Formation (Barail Group) of Oligocene age. The reservoirs rock is Mio-Pliocene age Sandstones of Bhuban and BokaBil Formation. Upper Marine Shale is clearly recognized from contour map and supposed to be a regional vertical seal in this area. The traps of fold belts are formed by the anticlinal folds along transverse fault. Intra-formational seals are also recognized from Fenchuganj well data. From google earth image and subsurface contour map, the best possible prospect might be against transverse fault.
