SHEARWATER GEOSERVICES TO PERFORM SNE FIELD 3D SURVEY
Shearwater GeoServices announced the award of a high-density multi-azimuth 3D seismic acquisition contract over the SNE field offshore Senegal by Woodside Energy (Senegal) B.V in its capacity as Operator of the SNE Field Development Joint Venture.
The contract covers the Sangomar, Sangomar Deep and Rufisque (RSSD) Offshore blocks which include the SNE discovery.
The work, designed as high density and multi-azimuth survey, will be acquired by the Polar Marquis using 14 streamers, and FlexiSource triple source. Starting in early Q3 2019, the survey will take approximately 90 days to complete.
“We are pleased to see the award by Woodside of this complex multi-azimuth triple source contract over these significant Senegal discoveries” said Irene Waage Basili, the CEO of Shearwater GeoServices. “The award reflects our capabilities as a full-service geophysical service provider and the Polar Marquis’ excellent record operating offshore Africa.”
SNE is a deep-water oil field discovery located in the RSSD Blocks, which cover an area of 7,490m² within the Senegalese portion of the Mauritania-Senegal-Guinea-Bissau-Conakry Basin.
Situated at a water depth of 1,100m, at about 100km south of Dakar, the SNE oilfield was discovered with the drilling of the SNE-1 exploration well in November 2014. The deep-water field was further appraised by more than ten appraisal wells between 2015 and 2017.
The oil reserves are hosted within the Cretaceous-age sandstones containing recoverable reserves of 32° API oil gravity, at a depth up to 3,000m beneath the sea bed. The oilfield is estimated to hold 2.7 billion barrels of recoverable oil reserves out of which, 230 million barrels will be recovered under the SNE phase one development project.
Development was initially undertaken by Cairn Energy, ConocoPhillips (operator), FAR, and Petrosen. Woodside Energy acquired 35% interest in the joint venture from ConocoPhillips to become the project operator in July 2016.
