  • Patent number: 11518930
    Abstract: An aqueous cross-linking suspension composition having brine, water-soluble suspending agent and borate cross-linker in a single package and methods for using the package composition for increasing the efficiency of fracturing subterranean formations and effectively delivering borate cross-linkers.
    Type: Grant
    Filed: July 14, 2020
    Date of Patent: December 6, 2022
    Assignee: Univar USA Inc.
    Inventors: Abdelaziz Rahy, DeWitt Knox, Mohand Melbouci
  • Patent number: 11319482
    Abstract: The present disclosure relates to compositions and methods for recovery of hydrocarbons from subterranean formations. The compositions may be dry blends of synthetic and naturally derived polymers. The blend compositions may also be produced as high activity solvent-based fluidized polymer suspensions. Either in dry or liquid forms, the blend compositions provide higher proppant carrying capacity in comparison to conventional solutions, as well as improved breakability and crosslinking capacity.
    Type: Grant

  • Patent number: 10150909
    Abstract: Methods, fluids, compositions, and suspensions are provided for treating subterranean formations. The fluids can be servicing fluids, such as drilling or fracturing fluids. The fluids may include an aqueous base fluid and a polysaccharide. The aqueous base fluid may be admixed with a crosslinker suspension. The crosslinker suspension may include an emulsion, an emulsifier, and a boron containing compound.
