Tender awaited for Bu Hasa upgrade

01 November 2002

Abu Dhabi Company for Onshore Oil Operations (Adco) is expected to release tender documents by the end of October for the engineering, procurement and construction (EPC) contract covering the Bu Hasa production facilities upgrade and reservoirs development project (MEED 30:8:02; 26:7:02).

Up to six companies are expected to submit technical bids by 31 January. A provisional deadline of 16 April has been set for the submission of commercial bids.

The prospective bidders are Italy's Snamprogetti, Paris-based Technip-Coflexipwith the local National Petroleum Construction Company, Chiyoda Corporation and JGC Corporation, both of Japan, and Fluor Danieland Kellogg Brown& Root, both of the US.

The project is estimated to cost $300 million-350 million and is effectively an expanded version of the surface upgrade and gas reinjection schemes, which Adco had tendered previously.

The scope of works on the 32-month contract includes the construction of a new degassification plant with a nameplate capacity of 730,000 barrels a day (b/d) and the replacement of the existing two-phase gas separators, each of of 50,000 b/d, with four new three-phase separators, each of 120,000 b/d.

The project will also entail the installation of facilities for the reinjection of 95 million cubic feet a day of gas and 120,000 b/d of water into the G, F and D reservoirs (MEED 19:7:02). It will tackle a rising water cut and falling reservoir pressure. A re-engineering study for the project has been carried out by Snamprogetti.

The US' Parsons International is acting as project management consultant for the scheme (MEED 6:9:02).

Project activity is on the rise at Adco. In addition to the Bu Hasa project, bidding is under way for the Bab field expansion and Northeast Abu Dhabi scheme (MEED 18:10:02).
