Saltpond Oil Field is an oil field off the coast of Ghana. The field was discovered in 1970 by Signal-Amoco Consortium. The field is currently managed by the Saltpond Offshore Producing Company (SOPCL), Ghana's oldest producer of crude oil.
The oil field is located 65 miles (105 km) west of Ghana's capital, Accra, in the Central region of Ghana. It is located about 13 kilometres (8.1 mi) off the coast of Saltpond in the northern-central area of the Takoradi Arch, in water depth of 80 feet (24 m). It extends over an area of 5 square kilometres (1.9 sq mi).
Saltpond Oil Field was discovered in 1970 after the Ghana National Petroleum Corporation (GNPC) licensed Signal-Amoco Consortium to operate in Ghana's territorial waters. The initial appraisal of the field showed that the well would produce 3,600 barrels per day (570 m3/d) of oil.
In 1976 Amoco relinquished the concession, citing the field as non-commercial. The concession was reassigned to Offshore Hydrocarbons Ltd., which later entered into a development farmout with Agri-Petco of the United States. In 1977–1978 Agri-Petco drilled six appraisal wells from a centrally located jackup rig called Mr. Louie. After the drilling, the jack-up was converted into a production unit and the field was put onstream in October 1978.
In 1984, the field was reassigned to Primary Fuels Inc., which took over the operation for a year. In July 1985 GNPC took over the operation of the field.
From 1978 to 1985 the maximum oil production was 4,800 barrels per day (760 m3/d) of oil. When operation stopped in 1985, the volume of production was 580 barrels per day (92 m3/d). The estimated percentages of oil and gas that had been obtained from the field at the time of shutdown were 10.4% and 25%, respectively, with three of the six wells unable to produce oil.
On 18 January 2000, GNPC entered into an agreement with Lushann International of Houston, Texas, for the rehabilitation of the Saltpond Oil Field and the implementation of the rig-less workover proposal. Lushann International contracted Eternit Universal Ltd. of Nigeria for the financing of the rehabilitation works. In August 2000, rehabilitation works commenced with the repair of the Mr. Louie platform. In 2002, Oildata's programme of rig-less workover discovered obstructions in the wells which prevented workers from reaching the bottom of most of the wells. When the workover was completed, only two wells were able to produce between 480–600 barrels per day (76–95 m3/d) of oil. Lushann International was also granted the right to develop up to 400 MW of power generation facilities to commercialize natural gas from the Saltpond Field.
