The scheme aims to boost output from the Qusahwira, Bida al-Qemzam, Ruwais and Bab onshore fields.

One source close to the project tells MEED that Amec submitted the lowest bid. It previously won the initial project management consultancy contract in 2007, but the contract was retendered for reasons that are still unclear (MEED 20:4:07).

Amec is expected to assist the US’ Washington Group International, the front-end engineering and design contractor on the scheme. The work includes the drilling of production wells, construction of gas-oil separation plants and interfield pipeline networks in the five fields.

It does not include the Shah, Asab and Sahil (Sas) full-field development, which is being handled separately by Adco. Two packages for the development of the Sas fields are expected to be awarded to UAE-based Petrofac International and a joint venture of Spain’s TR and Athens-based Consolidated Contractors International Company (CCC) by the end of October.

Petrofac is expected to win Package A, which covers work on the Asab field, while the TR/CCC group is the frontrunner for Package B, covering two main oil lines connecting Sahil and Shah to Asab.
