  • HIGH STABILITY POLYMER COMPOSITIONS WITH SILOXANE POLYETHER COMPOUNDS FOR ENHANCED OIL RECOVERY APPLICATIONS
    Publication number: 20240124711
    Abstract: Liquid polymer and inverse emulsion compositions comprising: one or more hydrophobic liquids having a boiling point at least about 100° C.; one or more acrylamide-(co)polymers; one or more emulsifier surfactants; one or more inverting surfactants; and one or more siloxane polyether compounds. When the composition is inverted in an aqueous solution, it provides an inverted solution having a filter ratio using a 1.2 micron filter (FR1.2) of about 1.5 or less.
    Type: Application
    Filed: December 13, 2023
    Publication date: April 18, 2024
    Inventors: Hong YANG, Frances TROY

  • HIGH STABILITY POLYMER COMPOSITIONS FOR ENHANCED OIL RECOVERY APPLICATIONS
    Publication number: 20220127518
    Abstract: Disclosed are methods of using liquid polymer and inverse emulsion compositions comprising one or more hydrophobic liquids having a boiling point at least about 100° C.; one or more acrylamide-(co)polymers; one or more emulsifier surfactants; one or more inverting surfactants; and one or more stabilizing agents (e.g., one or more siloxane polyether compounds, one or more poly(alkyl)acrylate compounds, or any combination thereof). When the composition is inverted in an aqueous solution, it provides an inverted solution having a filter ratio using a 1.2 micron filter (FR1.2) of about 1.5 or less. The inverted solutions can be used in oil and gas operations.
