Petrosen’s plans include new wells targeting the S410 gas reservoirs in the southern part of the Sangomar field, near Cap Skirring and the maritime border with Guinea-Bissau. The development also calls for modifications to the Sangomar FPSO and a subsea pipeline connecting the offshore facilities to a new onshore gas treatment plant at Ndiass. FEED and related studies are being advanced as Senegal works to define the infrastructure required to move the project forward.

An initial delivery rate of 70 million standard cubic feet per day (MMscfd) is targeted by the end of 2029, rising to 100 MMscfd from 2030 as the project scales. The development would provide another source of domestic gas for Senegal as the country moves to expand gas-fired power generation and reduce its reliance on imported fuels.

A final investment decision is targeted for Q1 2027, with FEED studies under way. Woodside Energy, which operates the Sangomar development with an 82% interest alongside Petrosen’s 18% stake, is also engaged with Petrosen on the field’s future development. Woodside says the initial Sangomar phase was designed to test additional reservoirs and support potential future gas export to shore.

The project sits within Senegal’s broader gas-to-power strategy. Petrosen says Sangomar contains approximately 4 trillion cubic feet of associated and non-associated gas, with future phases intended to support gas production for electricity generation and local LPG supply. The company is also developing a national gas network designed to connect domestic gas resources to power plants and industrial users, including facilities in the Ndiass economic zone and the planned Ndayane port.

That infrastructure buildout is creating opportunities well beyond upstream production. A commercial gas-to-shore system will require offshore wells and subsea infrastructure, pipeline engineering, gas processing, compression, construction, operations and maintenance, creating potential work for international contractors and Senegalese companies as the domestic gas supply chain expands.

The development also builds on Sangomar’s growing role in Senegal’s energy economy. In February 2025, the Société Africaine de Raffinage processed national crude from Sangomar for the first time, establishing a direct link between the offshore field and Senegal’s refining system.

Sangomar gas could extend that integration from crude and refining into power and industry, providing an additional domestic source alongside gas from the Greater Tortue Ahmeyim project and the future development of the Yakaar-Teranga resource.

The Sangomar gas valorization project and Senegal’s wider energy buildout will be featured at MSGBC Oil, Gas & Power 2026, taking place December 1–3 at the CICAD in Dakar, Senegal, under the High Patronage of President Bassirou Diomaye Faye. As Senegal moves from first oil toward a broader domestic gas economy, the event will bring together governments, operators, investors and service companies around the infrastructure and investment opportunities emerging across the country’s energy value chain.
