20140251596 | SINGLE VERTICAL OR INCLINED WELL THERMAL RECOVERY PROCESS - The present disclosure describes a single well predominantly gravity-dominated recovery process for producing viscous hydrocarbons from a subterranean oil sands formation.

The well pair includes: a generally horizontal segment of a hydrocarbon production well, and a generally horizontal segment of a combustion gas production well. The generally horizontal segment of the combustion gas production well is generally parallel to and spaced vertically above the horizontal segment of the hydrocarbon production well. The segment of the oxidizing gas injection well is spaced generally above the segment of the hydrocarbon production well and generally above the segment of the combustion gas production well. | 11-27-2014 |

20160061014 | HYDRAULICALLY UNITARY WELL SYSTEM AND RECOVERY PROCESS (HUWSRP) - The present disclosure describes a method of recovering viscous hydrocarbons from a subterranean formation using a gravity dominated recovery process with a group of wells, the recovery process incorporating an interwell recovery phase. The group of wells is initially operated independently to establish hydraulic communication between two or more wells in the group. Once hydraulic communication is established, injection of mobilizing fluid and production of hydrocarbons continues in at least one well within the group with an excess amount of mobilizing fluid being injected into the well. At the same time, production only continues in at least one well within the group, without any injection of mobilizing fluid. The wells in the group are spaced closer together than in conventional recovery processes. The recovery process may be SAGD. | 03-03-2016 |
