Abstract: Methods and systems produce petroleum products by insulating a thermal hydrocarbon recovery process from heat loss to surrounding areas of a formation utilizing an insulating composition including a non-gaseous phase component introduced into the reservoir that is different from water and insoluble in the hydrocarbons. The insulating composition may be disposed in the reservoir adjacent to where the heat loss is desired to be limited. In addition, the insulating composition may be disposed in a thief zone and may also be from an agent activated to form the composition at such desired locations by selecting activation dependent on at least one of temperature, time delay and oil saturation.

Abstract: A particularly effective well configuration that can be used for single well steam assisted gravity drainage (SW-SAGD) wherein steam flashing through production slots is prevented by including passive inflow control devices (ICDs) or active interval control valves in the completion. A thermal packer separates the injection and production segments of a horizontal well having a toe and a heel, and the ICDs can be evenly spaced or can decrease towards the heel. The cumulative steam to oil ratio (CSOR) of the SW-SAGD well is thus lowered, as compared to the same well without passive flow control devices or active interval control valves.

Abstract: The present invention relates to a method for reducing solvent retention in ES-SAGD process so as to increase process economics wherein an anti-retention agent is injected into the reservoir to decrease solvent retention in the reservoir. The anti-retention agent can be made pre-injection or can form in situ, and comprises an agent in which the solvent is readily soluble, such that the solvent partitions into the foam, colloidal dispersion, or gel, and out of the condensed water or steam, and away from the reservoir rock.

Abstract: A method of drilling a first well and a second well into the reservoir includes forming a conduit between the first well and the second well. The conduit is filled with a conduit material. Finally, a low viscosity fluid is injected into the conduit to establish fluid communication between the first well and the second well.

Abstract: A method for removing trace levels of oxygen from combustions products includes delivering fuel, oxidant and water into a direct combustion device. The fuel, oxidant and water are combusted in the direct combustion device to produce the combustion products. The combustion products include steam with trace levels of oxygen. The combustion products are then delivered to a scrubber for removal of oxygen. The scrubber includes a material capable of reacting with the oxygen.

Abstract: Thermal recovery of oils is improved by capturing waste heat from a depleted steam chamber using steam plus foam and an optional gas to carry low quality steam deep into the chamber where the waste heat converts water to steam in situ. Thus, overall steam generation needs and thus costs are reduced.
