Aramco, the world's largest oil supplier, plans to invite prequalified companies to bid for an estimated $3 billion worth of contracts on the company's largest-ever offshore project.
The estimated $10bn Manifa development programme aims to add 900,000 barrels a day of heavy crude, 120 million cubic feet a day of gas and 50,000 barrels a day of condensate to Aramco's production by mid-2011.
Manifa's heavy crude will be exported from Aramco's Al Juaymah and Ras Tanura terminals in eastern Saudi Arabia. The gas and the condensate will be processed at the Khursaniyah gas plant.
The project also includes construction of four pipelines, a water supply system and oils and gas processing facilities.
The tender documents for the project were originally due to be released in June or July but have been delayed without explanation, sources familiar with the Aramco's tender said.
Companies including Bechtel, Fluor Corporation, JGC Corporation and Technip in late May submitted prequalification documents to Saudi state-owned company. They are still waiting for final to bid, sources said.
In February, Aramco awarded an estimated $1bn contract to Belgium contractor Jan De Nul for the Manifa project's offshore portion, covering dredging works in the Gulf.
Middle East oil producers are spending income generated from four years of high oil prices on expanding and upgrading their crude oil production capacity to meet rising global demand, particularly from fast-growing Asian economies.
