US DOE backs enhanced oil recovery and CO2 sequestration
The Energy Department is proceeding with research into technologies that use industrial carbon dioxide to increase
yields from oil and gas fields while also sequestering the CO2, which is linked to global warming.
DOE's Office of Fossil Energy has begun soliciting proposals for enhanced recovery using CO2 that gives a preference to CO2 diverted from industrial sites such as ethanol and gas processing plants, refineries, coal liquefaction plants and other facilities.
A DOE-backed study last year estimated that enhanced recovery techniques using CO2 flooding could eventually yield
around 43 bn barrels of oil. Traditional recovery methods generally leave the majority of a field's oil in
The proposals will fund projects for testing and validating technologies that integrate enhanced recovery and CO2 sequestration, DOE said. A call for proposals earlier this month says the goal is to demonstrate the technology on commercial scale. The projects require a 50 % cost-share by the recipient.
The total estimated federal funding will be $ 7 mm to $ 8 mm, with DOE expecting to fund two to four projects.
The demonstration programs are mandated by the recently enacted energy law, which requires that priority be given to projects in the Williston Basin in North Dakota and Montana, and a project in Alaska's Cook Inlet basin. But applications will be accepted for projects in any region, the grant announcement states.
The Bush administration's budget request seeks to phase out the oil and gas drilling technologies program, but
Congress has blocked prior efforts to kill it.
The program DOE announced would be funded with existing money and hence would not be affected by the phase-out effort, according to DOE.
