ENI has formally asked Yinson Production to lift gas processing capacity on the FPSO serving Ghana's Sankofa-Gye Nyame field, Africa Oil+Gas Report has reported, in a move that could redirect more offshore molecules into the West African country's constrained power sector.

The request covers the FPSO John Agyekum Kufuor, the production unit moored over the Offshore Cape Three Points (OCTP) block in the Tano Basin, roughly 60 km off Ghana's Western Region. ENI Ghana, a subsidiary of the Italian major, operates the block with partners Vitol Upstream Ghana and the Ghana National Petroleum Corporation (GNPC). Yinson Holdings' production unit holds the bareboat charter and operations contract for the converted vessel that serves as the OCTP host.

The Sankofa-Gye Nyame development was the first commercial oil and gas project to reach first production in Ghana's deepwater. ENI and partners sanctioned the project in 2014 and brought it on stream in May 2017, with oil offloaded via shuttle tanker and associated gas exported to shore.

What is ENI seeking?

The report does not detail the targeted throughput. The request, as framed by Africa Oil+Gas Report, points to a lift in the FPSO's gas-handling envelope — most likely through topsides processing modifications or additional modules — to free more volumes for export through the gas pipeline.

The vessel was designed to handle oil production, water injection, gas reinjection for reservoir management, and gas export to shore. It carries a disconnectable spread sized for the OCTP reservoir and water depths in the block.

Why the gas lift matters

OCTP gas travels via a dedicated subsea pipeline to the Ghana National Gas Company (GNGC) processing plant at Atuabo, where it is treated and dispatched into the Western Corridor gas pipeline network supplying the Volta River Authority's thermal plants at Aboadze and the Tema enclave.

Ghana's power sector has run short of gas for several years, with the country importing LNG cargoes through the Tema regasification terminal to backfill shortfalls. West African Gas Pipeline volumes from Nigeria have remained intermittent, leaving OCTP and other domestic fields as the principal suppliers.

ENI has publicly framed OCTP as a national gas security asset, with production allocated preferentially to the domestic market under the OCTP Gas Sales Agreement, brokered through GNPC. Any incremental gas from Sankofa would land directly at Atuabo, where it could displace some LNG demand if the upgrade advances.

What to watch

Yinson's engineering response and ENI's formal approval of any topsides modification will set the timeline. A capacity lift would likely require a planned FPSO shutdown window, similar to previous maintenance campaigns that interrupted Sankofa-Gye Nyame production.

Ghana's upstream regulator and the Ministry of Energy will also need to confirm that the additional gas falls within the current offtake envelope, or whether a new gas sales amendment is required. That determination, more than the FPSO engineering itself, will likely pace the project.

The next trade-press signal will be any Ghana Petroleum Commission filing, a Yinson quarterly disclosure addressing topsides modifications, or a non-binding heads of terms with GNPC.
