Zakum Development Company (Zadco) has awarded a detailed engineering, procurement and construction management (EPCM) services contract to Mott MacDonald of the UK for the fabrication and installation of gas injection topsides at the Upper Zakum field (MEED 26:8:05). The project is aimed at the reinjection of 135 million cubic feet a day (cf/d) of additional gas into the oil reservoir to maintain pressure and is part of the Zakum gas treatment plant (GTP) project. Paris-based Technip is carrying out the front-end engineering and design (FEED) contract.
Estimated to be worth $350 million-400 million, the 34-month project will call for the installation of topsides, separators, compressors and gas turbines. Zadco plans to tender the construction package in the third quarter.
Zadco plans more reinjection work. The Hague office of the Netherlands' Tebodin is carrying out the nine-month FEED package on the Satah field development project. It will centre on the supply and installation of gas injection compressors, treatment units, separators and four 20-kilometre pipelines at onshore Arzana. The scheme will involve the reinjection of 10 million 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.
The FEED package is due to be completed by October, with a tender targeted to be issued in late 2006 for the engineering, procurement and construction (EPC) contract. Mott MacDonald is providing project management consultancy (PMC) services (MEED 16:12:05).
