0

Cairn Energy is assessing tender responses for the FPSO facility and subsea infrastructure for its SNE field development, offshore Senegal, ahead of the front end engineering and design (FEED) phase planned for the fourth quarter of this year.

Cairn, as operator, has a 40% working interest in three blocks offshore Senegal (Sangomar Deep, Sangomar Offshore and Rufisque Offshore) alongside partners, Woodside 35% WI, FAR 15% WI, and the Senegal National Oil Company, Petrosen 10% WI, which has the right to increase its equity to 18% on development.

Cairn announced that approval for the exploitation plan submission and approval was on track for the second half of 2018 with a final investment decision to follow in 2019 and first oil targeted for 2022. Formal transfer of operatorship to Woodside was expected in Q4 2018 and key work streams had already been delegated, the company said.

The SNE field covers 350km2 with two distinct horizons featuring a stacked series of S400 upper reservoirs overlying S500 lower reservoirs.

A series of phases has been proposed for development of the SNE field targeting the S500 resource with up to 26 subsea oil production, water injection and gas injection wells tied back to an FPSO with a production capacity of 100,000 bopd, located towards the eastern edge of the field in 800m water depth.
