Title: Interpretation of 2 – D Seismic Data and Reserve Estimate Of Block 10 of Saltpond Basin, Ghana
Authors: Coffie, Isaac Sonful
Issue Date: 19-Jun-2011
Abstract: Seismic interpretation and volumetric calculations were used to generate prospects and to estimate the possible reserves contained in the block 10 of the Saltpond basin of Ghana. Using the Takoradi 11- 1 well as the control point, mapping of the seismic reflections and picking of faults were carried in the study area. Four horizons were interpreted and these horizons are the sea bed, top of the Lower Cretaceous, top of a reservoir within the Lower Cretaceous and the top of the Paleozoic. Six main prospects were delineated, four at the Paleozoic level and two prospects at the Cretaceous level. The prospects are mainly fault blocks, faulted anticline and fault bounded unconformity. The prospects have area dimensions ranging from a minimum of 13.9 km2 to a maximum of 77.5 km2 located within depths of about 1990 m and 3385 m deep making them good exploration targets. Reserve estimations were carried out. A total of approximately 120 billion cubic feet (bcf) and 0.42 billion cubic feet of recoverable gas reserves have been estimated at the Paleozoic level the Lower Cretaceous level respectively. Faults, folds and unconformities can be picked up as the main structural and stratigraphic elements associated with hydrocarbon entrapment in the study area. The Paleozoic level was noted as the main exploration target since it has a potential of producing hydrocarbon especially gas in commercial quantities. The main exploration risk for the block is that the structures are mostly fault related which without proper sealing could leak petroleum out.
