The contract was awarded to a consortium led by France's SNF with the UK's Mott MacDonald as design contractor and Oman's Bahwan Engineering Company as construction contractor.

It involves building centralised water treatment and polymer preparation and injection facilities as well as the supply of chemicals for five years.

"This is an important strategic enhanced oil recovery project that will play an important role in sustaining Oman's long term oil production," PDO Managing Director John Malcolm said.

The Marmul field was discovered in 1956 and is located in the South of Oman. "The main Al Khlata reservoir has very heavy, viscous crude and production will be substantially increased using polymer flooding as an enhanced oil recovery technique," a PDO spokesman explained.

Polymer flooding works by adding polymer to water in order to make it more viscous before it is injected into the reservoir. Increasing the viscosity of water leads to a more effective oil sweep which increases both production and the ultimate recovery factor.

"The project will lead to a 10 per cent increase in the oil recovery factor from Al Khlata reservoir," the spokesman said. The project will be completed in 2008.

The centralised water treatment facilities will include a primary produced water treatment plant with capacity of 80,000 cubic metres a day (cmd) and a secondary produced water treatment plant with capacity of 30,000 cmd.

The polymer preparation and injection facilities station will have a capacity of 17,500 cmd.
