  • Patent number: 12312535
    Abstract: Functionalized foaming agents can be used to produce and improve stabilized foamers for use in the recovery of petroleum products from subterranean formations. In some embodiments, the functionalized foaming agent includes at least one nanoparticle, at least one polymer, or a combination thereof, where the nanoparticle(s), the polymer(s), or the combination thereof includes a functional group from a donor molecule. Suitable donor molecules include organosilicon molecules, alkyl halides with a chain of eight or more carbon atoms, and combinations of the same. In other embodiments, the functionalized foaming agent includes at least one nanoparticle, at least one polymer, or a combination thereof and a carrier fluid. The functionalized foaming agent can be introduced into a well or reservoir as part of an enhanced oil recovery (EOR) by injecting slugs of the functionalized foaming agent and slugs of gas in an alternating pattern to produce a foam.

  • Patent number: 11186500
    Abstract: Methods and additives for reducing fouling in water coolers in Steam Assisted Gravity Drainage systems (SAGD) are described in which an additive comprising a cationic starch, either alone or in combination with a water clarifier compound, is introduced into a SAGD system, wherein a lower amount of the additive is used to achieve the same or better results in reducing fouling in the water coolers as compared to an otherwise identical method absent the additive.

  • Patent number: 10913011
    Abstract: A system for monitoring phase separation is disclosed. The system includes a temperature control housing having an inlet and an outlet connection for a circulator; a bottle holder positioned inside the housing, the bottle holder having a body with a plurality of recesses for receiving test bottles, each recess having a back surface, a front opening, and a first light scanning component mounted on the back surface of the recess; a sleeve having a plurality of second light scanning components mounted thereon, the sleeve being disposed between the housing and the bottle holder, and each second light scanning component being aligned with one of the first light scanning components; and a lid latched onto the housing to hold the test bottles in place during testing.
