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.
Following completion of major upgrades at the OCTP’s non-associated gas (NAG) system, gas processing capacity rose to 270 MMcfd on July 13, up 24 MMcfd from the system’s previous capacity of 246 MMcfd, Eni said on July 15.
In addition to increasing gas supply to Ghana’s domestic market, the completed upgrading project further supports the nation’s commitment to a more sustainable energy future by allowing the country to reduce its current reliance on oil-fueled power generation in favor of a cleaner energy source, according to the operator.
To date, production of natural gas from OCTP powers about 34% Ghana’s electricity, Eni said.
Operational since August 2018, Eni—which holds a 44% stake in the project and acts as operator for partners VUGL (35.6%) and GNPC (20%)—said the OCTP provides about 70% of Ghana’s total domestic gas supply, mainly for electricity generation (OGJ Online, July 6, 2018).
Confirmation of the NAG system capacity expansion follows Eni Ghana’s late-May 2025 announcement that it will drill a sidetrack well in OCTP block to increase value and ensure long-term production sustainability of the project (OGJ Online, June 2, 2025).
System overview
An integrated project for development of oil and natural gas fields in 520-990 m of water, OCTP’s Sankofa and Gye Nyame fields are developed with wells and systems on the seabed, connected to the John Agyekum Kufuor floating production and storage unit (FPSO).
Gas is processed and transported via pipeline to onshore terminals near Sanzule where it is compressed and injected into the Western Corridor Gas Pipeline to be distributed to thermal power plants and industrial customers across the country. 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 work of the NAG system in early 2023 to boost capacity to 260 MMcfd.
In 2024, Eni Ghana also completed additional modifications required to increase capacity of the NAG system from the FPSO to OCTP’s onshore receiving facility (ORF), which included changes in orifice plates and Joule-Thompson (JT) valves, Petroleum Commission Ghana said in its 2025 Ghana Upstream Petroleum Business Report dated May 2025.
