Energean Oil & Gas has appointed TechnipFMC as the concept and FEED contractor for the Karish and Tanin development program offshore Israel, the company said in a news release Feb. 2.

The move followed Energean’s recent decision to develop the fields using an FPSO unit. Energean believes this will facilitate the quickest route to market.

The fields are said to contain 68 Bcm (2.4 Tcf) of gas. Energean said it plans to fast the Karish Field development, followed by development of the Tanin Field.

The company intends to submit the field development plan to the Israeli government in mid-2017. Development costs are expected to run between an estimated $1.3 billion and $1.5 billion over the next few years, Energean said.
