Abstract

The present disclosure describes a single well predominantly gravity-dominated recovery process for producing viscous hydrocarbons from a subterranean oil sands formation. The process operates a single vertical or inclined well within a formation, the wellbore having an injection means and a production means, the injection means being positioned in the wellbore closer to the surface than the production means. The process provides an area of high mobility adjacent the production means. A mobilizing fluid is injected through the injection means into the formation to mobilize the viscous hydrocarbons in the formation while substantially concurrently producing hydrocarbons through the production means. The gravity dominated process may be SAGD and the present process may be a single vertical or inclined well SAGD process.
