  • Well cementing with water-based liquid anti-shrinkage additives
    Patent number: 10982127
    Abstract: A method including introducing a well cementing composition into a wellbore, the cementing composition including a pumpable slurry of cement comprising a liquid anti-shrinkage additive including: an aqueous base fluid; a calcined magnesium oxide; and an anti-hydration agent; and allowing at least a portion of the cementing composition to harden. A liquid anti-shrinkage additive for cement including an aqueous base fluid, a calcined magnesium oxide, and an anti-hydration agent.
    Type: Grant

  • Surfactants for use in liquid suspensions of lightweight beads
    Patent number: 10723934
    Abstract: A method for suspending lightweight beads in a fluid includes combining lightweight beads, a fluid, and a surfactant to form a liquid additive. The liquid additive may be used to reduce the density of a wellbore fluid. The liquid additive or wellbore fluid can be combined with a cementitious material to form a lightweight cement composition.
