Abstract
A process for recovering heavy hydrocarbonaceous oil in situ is disclosed. After a communication path is established between injection and production wells, a hot viscous fluid at least 20% of which is produced hydrocarbonaceous oil from the production well is circulated between the wells providing high sweep efficiency and good recovery of oil in place. In a preferred embodiment, the fluid comprises recirculated bitumen from the production well, steam, and small amounts of inert gas and emulsified water. The final stage is a recovery by conventional means.
