  • Oil recovery with insulating composition
    Patent number: 11225859
    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.
    Type: Grant

  • Anti-retention agent in steam-solvent oil recovery
    Patent number: 10597579
    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.
