The FEED package will take about nine months to complete, with a tender due to be issued in the third quarter of 2006 for the engineering, procurement and construction (EPC) contract.

Estimated to be worth $200 million-250 million, the project will centre on the supply and installation of gas injection compressors, treatment units, separators, four 20-kilometre pipelines and related facilities at the onshore Arzana site. The scheme will involve the reinjection of 10 million cubic feet a day (cf/d) of associated gas to maintain reservoir pressure at the offshore field. At present, Satah has production capacity of about 25,000 barrels a day (b/d). The UK’s Mott MacDonaldhas been awarded the project management consultancy (PMC) services contract.

A tender is due to be issued by Zadco in January for the PMC contract involving a major gas treatment and reinjection at the neighbouring Upper Zakum field. In late November, about five companies responded to the initial inquiry to carry out the contract (MEED 2:12:05).

Estimated to cost $350 million-450 million, the scheme will entail the construction of two new gas processing trains with total capacity of 380 million cf/d, a new production platform and related works. The successful PMC will also oversee a concept study for the Upper Zakum debottlenecking project, for which four companies submitted technical and commercial bids in October. The project is aimed at increasing production capacity to 750,000 b/d from 550,000 b/d (MEED 14:10:05).
