About Woodside Energy and Sangomar
Woodside Energy is the operator of the Sangomar field, Senegal’s first offshore oil development, which achieved first production in 2024. The initial phase of development includes 12 production wells, 10 water injectors, and 2 gas injectors, tied back via subsea infrastructure to a Floating Production Storage and Offloading facility with ~100,000 barrels of oil per day capacity.
Sangomar represents a strategic, high-impact asset in an emerging hydrocarbon basin, offering direct exposure to reservoir management, production optimisation, and future development phases. The asset provides an opportunity to work within a multicultural, high-performing team across Dakar and Houston, while contributing to Senegal’s energy future and long-term resource development.
