Ghana’s next oil bet: Can the Voltaian Basin end the country’s dependence on offshore fields?
The Ghana National Petroleum Corporation (GNPC) says a rig could be on site by the end of the year. The big question is what happens to Ghana’s oil industry if the three main fields decline, and whether a basin drilled only once in 50 years can help. Ghana’s oil story has so far been written almost entirely at sea. Jubilee, TEN and Sankofa, the three fields that carry the country’s oil output, are all offshore. Now the national oil company wants to try something different: drilling on land. At the 2026 Petroleum Commission Local Content Conference, GNPC’s Chief Executive, Kwame Ntow Amoah, said the first piece of well equipment, the conductor casing, has already arrived at the drilling site. The company hopes to finalise its contracts and get a rig there by the end of the year. His reason was blunt: “It is simply too risky to depend on Jubilee, TEN, and Sankofa alone.” The place GNPC is looking at is the Voltaian Basin. Think of it as a huge underground bowl of rock that may hold oil and gas. It covers about 103,600 square kilometres, roughly 40 percent of Ghana’s land area.
