Abstract
Described is a method for downhole sequestration of carbon dioxide. A heating assembly is lowered into a wellbore within a geological formation. Carbon dioxide is injected into the wellbore and heated to a predetermined temperature using the heating assembly. The heated carbon dioxide is allowed to migrate from the wellbore into the geological formation for permanent storage. A monitoring operation is performed to detect the formation of gas hydrates within the wellbore.
