摘要： A process to recover hydrocarbons from a hydrocarbon reservoir, namely bitumen (API 100,000 c.p.), said process comprising; establishing a horizontal production well in said reservoir; separately injecting an oxygen-containing gas and steam into the hydrocarbon reservoir continuously to cause heated hydrocarbons and water to drain, by gravity, to the horizontal production well, the ratio of oxygen/steam injectant gases being controlled in the range from 0.05 to 1.00 (v/v). removing non-condensable combustion gases from at least one separate vent-gas well, which is established in the reservoir to avoid undesirable pressures in the reservoir.

摘要： A cyclic remediation process to restore oil recovery from a primary oil production well that has watered off from bottom water encroachment (cone or crest) whereby: (a) the primary oil production well has a produced water cut in excess of 95% (v/v); (b) the oil is heavy oil, with in-situ viscosity >1000 cp; wherein the process includes: (c) injecting a steam slug with a volume of 0.5 to 5.0 times the cumulative primary oil production, with steam volumes measured as water volumes; (d) shutting in the well for a soak period, after the steam injection is complete; and (e) producing the well until the water cut exceeds 95%.

摘要： A Single Well Steam Assisted Gravity Drainage (SWSAGD) process to recover liquid hydrocarbons from an underground hydrocarbon reservoir, wherein the single well includes a single substantially horizontal well including a heel area and a toe area, wherein the toe area of the horizontal well extends upwardly into the reservoir, the process including 1—injecting steam into the reservoir via a steam injection area, proximate the toe area of the horizontal well, 2—allowing the steam to condense causing heated hydrocarbon liquids and water to drain into a liquid recovery zone of the horizontal well between the toe area and the heel area of the horizontal well, and 3—recovering the heated hydrocarbon liquids to the ground surface from the liquid recovery zone.

摘要： There is provided a process for producing hydrocarbons from a reservoir. The process includes within the hydrocarbon reservoir, electrically heating a liquid heating fluid such that the liquid heating fluid is evaporated to produce a gaseous heating fluid, heating hydrocarbon material with the gaseous heating fluid such that the heated hydrocarbon material is mobilized and such that the gaseous heating fluid is condensed to produce a condensed heating fluid, and electrically heating at least a fraction of the condensed heating fluid such that the at least a condensed heating fluid fraction is re-evaporated, and while the evaporation, the condensing, and the re-evaporation are being effected, producing a produced fluid including at least the mobilized hydrocarbon material.
