Abu Dhabi Company for Onshore Oil Operations (Adco) has begun a enhanced oil recovery project in the emirate, the company said in a 8 April statement.

The project will test the injection of carbon dioxide into pilot wells in a carbonate reservoir in Abu Dhabi. A pilot scheme began operations at the end of 2009, with a continuous supply of 60 tonnes a day, or 1.2 million cubic feet a day, of carbon dioxide injected into one of the pilot wells.

Abu Dhabi-based Praxair Gulf Industrial Gases, a subsidiary of the US’ Praxair will supply the carbon dioxide and will carry out the injection operations under a contract with Abu Dhabi Future Energy Company (Masdar).

The state onshore oil operator plans to increase the emirate’s onshore oil capacity by 400,000 barrels a day (b/d) to 1.8 million b/d by 2015.

As part of the plan on 24 March, Adco awarded a $560m deal to build new oil and gas production facilities at the Qusawirah field in the south east of the emirate to local National Petroleum Construction Company (MEED 24:3:10).

The UAE as a whole has approximately 97.8 billion barrels of crude oil reserves. Abu Dhabi leads the other emirates with 92.2 billion barrels, followed by Dubai with 4 billion barrels, Sharjah with 1.5 billion barrels, and Ras al-Khaimah with 100 million barrels.
