COPENHAGEN, Denmark -- Maersk Oil has acquired licenses to a technique that can lift recovery from technically demanding or mature fields.
Clean Energy’s Oxy-Fuel technology uses pure oxygen to combust natural gas or other fuels to produce water, electricity and carbon dioxide (CO2). The system allows water and power to be provided to consumers, while the captured CO2 is diverted for enhanced oil and gas recovery projects, which Maersk claims ensures a zero emission operation.
The process, which took 15 years to developing, employs technology derived from the rocket industry. According to Maersk, commercial-scale tests are due to be conducted in California.
Maersk says the process can be used offshore and it is suited to low-quality gas fields containing CO2. The latter is separated from condensed steam following combustion, and can then be re-injected into a field to increase oil or gas recovery.
