The project will comprise the supply and installation of two wellhead towers and modifications to an existing unit, three subsea in-field pipelines and related works. The FEED package will take six months to complete.
The scheme is expected to be tendered to engineering, procurement and construction (EPC) contractors by the end of the year. Estimated to be worth AED 185 million ($50 million), it will be carried out on a fast-track basis. The client is Abu Dhabi Marine Operating Company (Adma-Opco), which plans to drill at least seven new wells at the Zakum field to increase output.
Adma-Opco also plans the development of the neighbouring offshore Umm Shaif field. Worley is carrying out the FEED package for a major gas reinjection scheme (MEED 26:7:02; 6:7:01). The estimated $1,200 million project, divided into two parts, calls for the reinjection of some 600 million cubic feet a day into the Umm Shaif reservoir to maintain oil production. The first, expected to cost $800 million, involves the installation of a new super-complex some four kilometres from the existing facilities at Umm Shaif. The remaining $400 million will be spent on drilling new wells and associated works. Stone & Webster, part of the US' Shaw Group, is acting as project manager for the scheme.
