  • Hydrophobically modified quaternized polysaccharide corrosion inhibitors
    Patent number: 10259995
    Abstract: A treatment fluid that includes an aqueous fluid, an inorganic acid, and a hydrophobically modified quaternized polysaccharide may be useful in mitigating corrosion of metal surfaces by the inorganic acid. For example, a wellbore operation may include introducing the treatment fluid into a wellbore penetrating a subterranean formation and contacting a metal surface with a treatment fluid.
    Type: Grant

  • Crosslinking resin for sand consolidation operations
    Patent number: 9567511
    Abstract: Methods including introducing a treatment fluid comprising a solvent-base fluid and a consolidation composition into a wellbore in a subterranean formation, the consolidation comprising, a crosslinking diverting agent, a hardening agent, and a multi-functional epoxy resin, the multi-functional epoxy resin comprising at least three epoxy groups; coating a face of the subterranean formation with the consolidation composition; and at least partially curing the consolidation composition in the wellbore, to reduce production of unconsolidated particulates from the subterranean formation into the wellbore.
