Production of heavy crude oil by heating
Patent
·
OSTI ID:6177025
A process for producing heavy crude oil from a stratum through a well penetrating the stratum and an aquifer below the stratum consists of burning fuel with injected oxygen-containing, combustion-supporting gas in an upper level of the aquifer subjacent to a heavy crude-bearing stratum. The oil in the overlying stratum is thereby heated, reducing its viscosity, and causing it to flow into a well from which it is recovered. Air is the usual combustion-supporting gas, but air enriched with oxygen or oxygen alone may be used. (10 claims)
