Abu Dhabi Marine Operating Company (Adma-Opco) has almost finished technical talks with bidders on its estimated $200-300m seawater injection project and plans to ask for prices for the deal by the end of 2009.

International engineering firms submitted their technical bids, outlining proposed engineering works, on 16 November. Discussions between contractors and Adma-Opco executives started in early December.

Executives at bidding firms say the talks were due to end on 10 December. Adma-Opco will ask for commercial bids outlining the cost structures of proposed deals before the end of December.

The winning bidder will build an offshore platform and water injection facilities. The new facilities will gather seawater and pump it into the oil reservoir to maintain pressure and ultimately production at the ageing field.

The project is part of a series of schemes by Adma-Opco to boost production at its offshore oil and gas fields. The company hopes to increase output from current levels of about 600,000 barrels a day (b/d) to 1 million b/d by 2015.

Abu Dhabi’s other offshore oil and gas operator, Zakum Development Company (Zadco), wants to boost production levels from 500,000 b/d currently to 750,000 b/d in a similar timeframe.
