Takula Oil Field and the Greater Takula Area, Cabinda, Angola
The Greater Takula area comprises four offshore fields that produce oil predominantly from Upper Cretaceous reservoirs. They are located approximately 40 km (25 mi) west-northwest of the Malongo terminal, Cabinda, Angola, in water depths between 50 and 75 m (165 and 230 ft). Current total production level is approximately 200,000 bbl of 32° API oil per day. The largest field is Takula, where oil was first discovered in rocks of Barremian age in 1971. However, it was not until 1979 that the giant oil accumulation in the Cenomanian section was tested. An estimated 2060 MMSTB of OOIP (original oil in place) was present in Takula field. By 1983, appraisal and exploratory drilling had found the prolific Greater Takula trend of rollover anticlinal structures striking northwest to southeast through Takula. These structures host Wamba, Takula, Numbi, and Vuko fields. Over 80% of the original oil in place is held in the Cenomanian Vermelha sandstone reservoirs. These reservoirs are a stacked sequence of nearshore sandstones deposited in a coastal environment. The Greater Takula area is now in a mature stage of development, having produced over 250 MMSTB from an OOIP of 3450 MMSTB.
