  • Patent number: 12187959
    Abstract: A polymer composition has been developed that comprising an oil-in-water emulsion comprising an aqueous phase comprising water and an emulsifying surfactant having a cloud point of less than 80° C. and a hydrophilic-lipophilic balance (HLB) of greater than or equal to 8, and an oil phase comprising a high molecular weight oil-soluble polymer, wherein the oil-soluble polymer comprises a copolymer derived from reaction of a hydrophobic monomer and an ionizable monomer in a weight ratio from about 999:1 to about 80:20. Methods of using the compositions for drag reduction and corrosion inhibition are also disclosed.
    Type: Grant

  • Patent number: 12173146
    Abstract: A polymer composition has been developed that provides low viscosity oil-in-water polymer emulsions that release the polymer in the emulsion at a faster rate and without an additional surfactant when the emulsion is added to a hydrocarbon stream. Use of a temperature-sensitive emulsifying surfactant facilitates inversion of the oil-in-water polymer emulsion when applied to a hydrocarbon composition at a temperature sufficiently high to destabilize the emulsion. These compositions are particularly useful as drag reducers for delivery to a subsea flowline via an umbilical line.

  • Publication number: 20240117799
    Abstract: The present disclosure is generally directed to an apparatus for pumping suspended polymer liquids that reduces the formation of polymeric deposits at the seal contact surfaces and filters out deposits that do form. This allows for an oil drag reducing agent (DRA) to be delivered continuously from topside through an umbilical to subsea produced fluids flowlines to increase oil production and/or flow of gas/oil by reducing friction loss due to turbulent flow in the flowlines.

  • Publication number: 20210095183
    Abstract: A polymer composition has been developed that provides low viscosity oil-in-water polymer emulsions that are stable to shear conditions and are storage stable at low temperature conditions (e.g., ?6.7° C. or less) or higher temperature conditions (e.g., up to 60° C.). Use of particular additives provides stability to the emulsion and imparts advantageous properties when the polymer composition is contacted with a hydrocarbon fluid. These compositions are particularly useful as drag reducers for delivery to a subsea flowline via an umbilical line.

  • Patent number: 10745608
    Abstract: The present invention generally relates to methods for removing deposits in an oil or gas well by contacting the annular fluid in a batch-wise method with an effective amount of a composition comprising a water-soluble copolymer. These methods are advantageous because they can be used as needed to improve well operation. The methods use a water-soluble copolymer comprised of an acrylamide monomer and one or more cationic monomer.
