Abu Dhabi Company for Onshore Oil Operations (ADCO) has initiated an enhanced oil recovery project that will test the injection of carbon dioxide (CO2) into pilot wells in a carbonate reservoir in the MENA region of Abu Dhabi.

Praxair Gulf Industrial Gases LLC, an Abu Dhabi-based subsidiary of Praxair, Inc., is supplying the required CO2 and injection operations under a contract with Abu Dhabi Future Energy Company (MASDAR).

The pilot began operations in the fourth quarter of 2009. A continuous supply of 60 tons per day (1.2 million standard cubic feet per day) of CO2 is being provided to ADCO and is being injected into one of the pilot wells.

“Praxair is very pleased to have been selected by MASDAR for this project,” said Eduardo Menezes, President of Praxair Europe.

“Carbon capture and storage, with the added benefits of enhanced oil recovery, is one of the potential solutions that will allow fossil fuels to continue to be used while protecting the environment.”

Praxair has been helping oil producers increase extraction and efficiency with carbon dioxide and nitrogen injection systems for more than 30 years.

Praxair’s largest enhanced oil recovery project to date involves two plants that deliver 6,800 tons of nitrogen per day to Pemex in southern Mexico.
