Petrosen has outlined the scale of investment needed to develop the Yakaar-Teranga deepwater gas field offshore Senegal, with the project expected to require around $7.5 billion.
The field is estimated to contain recoverable resources of approximately 25 trillion cubic feet of gas. The asset returned to Senegal in April 2026 after Kosmos Energy exited the block, giving Petrosen exclusive rights without compensation.
The handover was interpreted as prioritizing domestic energy supply over exports within the Greater Cayar Offshore Profond block north of Dakar.
New gas supply from the project could help Senegal reduce reliance on imports and lower annual energy subsidy costs estimated at about $1 billion once production reaches the domestic market.
Kosmos Energy had previously said it was working with Petrosen to identify a suitable partner and establish a commercially viable development concept. Senegal’s Ministry of Energy, Petroleum and Mines stated that the process did not reflect an intention to nationalize the project.
Senegal’s Energy, Petroleum and Mines Minister Birame Souleye Diop visited Petrosen on 30 April 2026 to review projects including Yakaar-Teranga. Discussions covered development progress, technical options, resource evaluation, environmental and social impacts, financing for a final investment decision, and marketing-related matters.
Petrosen said the project has reached a stage where an integrated gas chain development concept and advanced technical work can support entry into front-end engineering design. The company also stated that the project demonstrated economic viability supported by an offtake strategy.
Other major energy projects in Senegal include Woodside’s Sangomar field, which achieved first oil in June 2024 with the FPSO Léopold Sédar Senghor, and BP’s Greater Tortue Ahmeyim Phase 1 project offshore Mauritania and Senegal.
