  • Method for consolidating subterranean formation
    Patent number: 12584061
    Abstract: A system for consolidating particles in a subterranean formation includes a treatment fluid (e.g., a consolidation fluid) having a viscosity lower than 5 cP. The treatment fluid includes a resin system, a surfactant, and a curing agent. A method for consolidating particles in a subterranean formation includes preparing the treatment fluid, introducing the treatment fluid into the subterranean formation, and allowing the treatment fluid to cure to consolidate the particles in the subterranean formation.
    Type: Grant
    Filed: December 7, 2022
    Date of Patent: March 24, 2026
    Assignee: Schlumberger Technology Corporation
    Inventors: Nirupama Vaidya, Rasika Prabhu, Patrice Abivin
  • HIGH SOLIDS CONTENT FLUID TECHNIQUES
    Publication number: 20260043316
    Abstract: A method includes placing, via a bailer, a slurry into a wellbore to deposit a slurry downhole. The slurry includes a solids mixture and a fluid. The method also includes terminating placement of the slurry for a period of time. A viscous pill inhibits settling of the solids mixture, and the slurry displaces the viscous pill in contact with a surface of a screen.
    Type: Application
