Eni SPA subsidiary, Eni Ghana Exploration and Production Ltd.—on behalf of joint-venture (JV) partners Vitol Upstream Ghana Ltd. (VUGL) and Ghana National Petroleum Corp. (GNPC)—has expanded natural gas processing capacity of the JV’s integrated oil and gas development project on the Offshore Cape Three Points (OCTP) block, 60 km offshore western Ghana.
The OCTP’s non-associated gas (NAG) system, processing capacity for gas increased to 270 MMcfd on July 13 which is an increase of 24 MMcfd from the system’s former capacity of 246 MMcfd, upon completion of key upgrades, Eni reported on July 15.
Apart from enhancing the supply of gas to Ghana’s domestic market, the completed upgrading project further supports the nation’s commitment to a more sustainable energy future. Eni Ghana expands natural gas that will enable the country to reduce its current reliance on oil-fueled power generation in favor of a cleaner energy source, according to the operator.
Eni said, the production of natural gas from OCTP offers about 34% Ghana’s electricity till date.
To date, production of natural gas from OCTP powers about 34% Ghana’s electricity, Eni said.
Notably, the confirmation of the NAG system capacity expansion follows Eni Ghana’s late-May 2025 announcement. Eni Ghana expands natural gas that will drill a sidetrack well in the OCTP block that will guarantee long-term production sustainability and increase value of the project.
Operational since August 2018, Eni—which holds a 44% stake in the project and is operator for partners VUGL (35.6%) and GNPC (20%), reported that the OCTP supplies some 70% of Ghana’s entire domestic gas supply, primarily to generate electricity.
System overview
An integrated project for development of oil and natural gas fields has been built on 520-990 m of water, consisting of OCTP’s Sankofa and Gye Nyame fields that are developed with wells and systems on the seabed, that is connected to the John Agyekum Kufuor floating production and storage unit (FPSO).
The gas is processed and transported through pipeline to onshore terminals around Sanzule. The gas is then compressed and injected into the Western Corridor Gas Pipeline, further distributed to thermal power plants and industrial consumers nationwide. Oil is stored in the FPSO and offloaded to tankers for sale in the international market.
According to VUGL’s annual OCTP environmental and social monitoring report dated June 2024, the partnership completed debottlenecking of the NAG system in early 2023 to increase capacity to 260 MMcfd.
In 2024, Eni Ghana also completed additional modifications necessary to raise the capacity of the NAG system from the FPSO to OCTP’s onshore receiving facility (ORF), such as changes in orifice plate and Joule-Thompson (JT) valve, Petroleum Commission Ghana said in its 2025 Ghana Upstream Petroleum Business Report dated May 2025.
