Abstract
Offshore Togo, West Africa provides exciting potential for hydrocarbon exploration. Previous exploration is limited to four wells, drilled prior to 1986 in shallow water. This investigation focuses on a 625 km² section of 3100 km² of high quality 3-D seismic data acquired by Petroleum Geo-Services Inc. (PGS), Houston, Texas. The study area ranges from approximately 180 m - 2500 m water depth. Research included regional geologic correlation, seismic interpretation, and structural modeling of the major fault systems and unconformities. Proven source and reservoir formations from existing oil and gas fields in neighboring countries are analogous to formations identified on seismic for offshore Togo. Structures suitable for hydrocarbon accumulation were identified on seismic within potentially productive formations. Based on the correlations, seismic interpretation and modeling, four possible exploration prospects were identified. The prospects were ranked according to exploration potential based on structural characteristics and original oil in place (OOIP) calculations. The existence of suitable structures for hydrocarbon accumulation in potentially productive formations makes offshore Togo highly prospective.
