Abu Dhabi Company for Onshore Oil Operations (Adco) has invited six companies to submit the first set of technical bids by 4 February for the engineering, procurement and construction (EPC) contract covering the Bu Hasa production facilities upgrade and reservoirs development project. The second set of technical bids are due to be returned by 18 March (MEED 25:10:02; 30:8:02).
The prequalifiers are Italy's Snamprogetti, Paris-based Technip-Coflexipwith the local National Petroleum Construction Company, Chiyoda Corporation and JGC Corporation, both of Japan, and Fluor Daniel and 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 previously tendered.
The scope of works on the estimated 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 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. It will tackle a rising water cut and falling water 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).
