Commercial bids were submitted on 26 February for the front-end engineering and design (FEED) package on the project to develop two reservoirs at the onshore Bu Hasa field. Three companies - the multinational VECO, SNC Lavalinof Canada,and Paris-based Technip - are competing for the FEED for which technical bids were submitted in December.
The Bu Hasa unit G and unit F and D extension is aimed at the reinjection of at least 95 million cubic feet a day of gas and 120,000 barrels a day (b/d) of water into the reservoirs to maintain pressure. It is estimated to cost $80 million-100 million. The US' Bechtel has carried out the pre-FEED work.
The FEED package will take about seven months to complete. The 22-24-month project will be tendered in three packages. Package 1 will cover installation of a gas compression station. The second package will be for the installation of a booster/dehydration unit and a link to the central degassing station. Package 3 will include the installation of a gas pipeline from Bu Hasa to the proposed compression station.
The client is Abu Dhabi Company for Onshore Oil Operations (Adco), which is also planning to upgrade surface production facilities at Bu Hasa. Technical and commercial bids are due to be submitted by 19 March for the engineering, procurement and construction (EPC) contract. The estimated $200 million-250 million contract involves the installation of four new separation units, each of 120,000 b/d in capacity, to replace the existing two-phase units of 50,000 b/d each (MEED 11:1:02).
In addition, four gas/oil separation units will be upgraded and Bu Hasa's instrumentation and control systems will be modernised.
