  • Methods and compositions for cleaning interior of a casing string
    Patent number: 11186760
    Abstract: Aqueous fluids containing hydrophobic particles are effective media for cleaning water-base drilling fluids and drilling fluid solids from the interior surface of a casing string. Hydrophobic fibers may be added to a drilling fluid, a spacer fluid, a sacrificial spacer fluid, a chemical wash, or combinations thereof. The disclosed fluids may be employed during primary cementing operations where it is not possible to use a bottom plug.
    Type: Grant
    Filed: November 26, 2015
    Date of Patent: November 30, 2021

  • Shale stabilization fluids
    Patent number: 10793765
    Abstract: A method for treating a subterranean formation containing shale includes introducing to the subterranean formation a shale stabilizer, a surfactant, and a triggering agent simultaneously with or prior to introducing an alkali silicate to the subterranean formation, and allowing the alkali silicate and triggering agent to react to form a reaction product. Methods include coating the surface of at least a portion of the shale with the reaction product.

  • Compositions and methods for servicing subterranean wells
    Patent number: 10161222
    Abstract: Fluids containing surfactants and hydrophobic particles are effective media for cleaning non-aqueous fluids (NAFs) out of a subterranean wellbore. The fibers and surfactants are preferably added to a drilling fluid, a spacer fluid, a chemical wash, a cement slurry or combinations thereof. NAFs, such as an oil-base mud or a water-in-oil emulsion mud, are attracted to the fibers as the treatment fluid circulates in the wellbore.
