Enhanced Recovery and Carbon Sequestration
One form of enhanced oil recovery involves pumping CO² gas into the reservoir to push out the oil or natural gas. In addition to increasing recovery of the resource, enhanced oil recovery represents an opportunity to sequester carbon, thus preventing it from entering the atmosphere and contributing to global warming. CO² can also be used to recover coalbed methane. Tests have shown that CO² is roughly twice as adsorbing on coal as methane, giving it the potential to efficiently displace methane and remain sequestered in the coal seam. CO² recovery of coalbed methane has been demonstrated in field tests and more work is underway to optimize the process.
Raven Ridge Resources has the skills and expertise to undertake CO² enhanced recovery and sequestration projects in coalbed methane reservoirs. Raven Ridge Resources is currently investigating the potential for sequestering CO² in abandoned underground coal mines. Some of these mines are located near electricity generating facilities that are large point sources of CO² emissions. Thus, limited pipeline transport of the CO² gas would be required. Development of an abandoned mine carbon sequestration project would entail both methane recovery and sequestration of CO². Such projects integrate our expertise in geological characterization, reservoir engineering, mining engineering, and environmental science. They also incorporate our capabilities in the area of greenhouse gas offset credits, to maximize project profitability.
