Discovered 10 years ago about 62 miles south of the capital Dakar, Sangomar is expected to produce about 100 000 barrels per day (bpd).
A floating production, storage, and offloading vessel for the project operated by Woodside Energy arrived last year.
In a statement published on X, the ministry said that all wells had been brought online by end-2024 with a view to achieving the targeted output of 100 000 bpd.
It said Sangomar's output in December reached 2.96 million barrels of crude oil including three cargoes totalling 2.94 million barrels which were exported.
