Aberdeen-based operator Siccar Point Energy has made further progress towards the development of its Cambo field in the UK West of Shetland Area with the submission of environmental documents to the UK authorities.

An environmental statement (ES) covering the planned first phase of development at Cambo was recently submitted to the Offshore Petroleum Regulator for Environment & Decommissioning, part of the Department for Business, Energy & Industrial Strategy.

The ES is expected to be made public tomorrow (Friday 8 November).

In August, Upstream reported that Sembcorp Marine landed an exclusive front-end engineering and design contract for the design of a Sevan cylindrical floating production, storage and offloading vessel for the development.

Sembmarine has tapped US contractor KBR for topsides design and integration support with work being carried out in Singapore and Norway.

Speaking to Upstream in September, Siccar Point chief executive Jonathan Roger the company upped its estimates of oil in place at the field to 900 million barrels from a previous figure of 800 million barrels.

In terms of recoverable barrels at a “conservative recovery factor of 35%”, that would mean a “prize to get after” of 300 million barrels, he said.

Phase one, comprising the FPSO, gas export pipeline, two drill centres, nine production wells and four injection wells, will target 150 million barrels.

A final investment decision is being targeted early next year to allow for first production in late 2023, he added.

The FPSO will be designed with a production capacity of 60,000 barrels per day, which “we will be looking to fill as part of phase one and then keep the plateau with future phases”, Roger said.

Sembmarine has tapped US contractor KBR for topsides design and integration support.

Other FEED work is being undertaken by GE-controlled Baker Hughes for the wells, subsea and riser systems, and by Genesis for a gas export pipeline.

Storage capacity of the FPSO will be 650,000 barrels. Gas compression capacity for both gas lift and export will be 60 million cubic feet per day.

The Cambo field, located 125 kilometres north-west of the Shetland Islands in a water depth of 1100 metres, was discovered in 2002.

Anglo-Dutch supermajor Shell last year took up a 30% working interest in Cambo from private-equity-backed Siccar Point.
