As global warming due to anthropogenic greenhouse gases, notably carbon dioxide threatens to take a catastrophic dimension, geological
storage of carbon dioxide has been widely accepted as a technically and economically viable remediation strategy. Consequently, targeted
geological repositories are saline aquifers, salt caverns, deep unmineable coal seams and depleted oil and gas reservoirs. For storage in
depleted oil reservoirs, the stratigraphic trapping capability of overlying low permeability shale is the principal motivating factor for long
term containment of anthropogenic gas in oil reservoir until its dissolution and final immobilization by mineral carbonation reactions.
Consequently, where the development of the oil reservoir by thermal recovery can lead to thermal pressurization of the cap rock layer, the
ability of such a depleted reservoir to contain anthropogenic carbon dioxide must be thoroughly investigated to assess its competency as a
proposed geological repository. In this study, seismic theory coupled with that of heat transfer has been used to derive interval velocity for a
heavy oil reservoir under thermal recovery. The resulting equation has been validated using published works from literature sources.
Key words: carbon sequestration, heavy oil reservoir, heat transfer, acoustic logging, carbon dioxide emission.
