The Sangomar offshore oil field was formerly known as the SNE offshore oil field. It is located in the Rufisque, Sangomar, and Sangomar Deep Blocks, with a total area of 7,490km² within the Senegalese portion of the Mauritania-Senegal-Guinea Bissau Basin. Phase one works will feature deployment of a permanently moored floating production storage and offloading (FPSO) facility supplied by MODEC, a leading provider of solutions to the Floating Offshore Oil & Gas market, along with 23 oil production wells and associated subsea systems. With a length of between 250m and 325m, the FPSO which will also hold the tie-backs of the oil production wells, along with water injection and gas interjection wells will be installed at a water depth of 800m. This will allow the integration of subsequent development phases, including gas export to shore and future subsea tie-backs from other reservoirs and fields. The oil storage tank of the FPSO unit will have a capacity to hold up to one million barrels of processed oil.
