  • Patent number: 10472552
    Abstract: Spacer fluids are provided for use in cementing liners in oil and gas wells. The fluids comprise pumice and a suspending agent. Pumice is the first-in weighting agent and is added in amounts sufficient to stabilize the rheology of the fluid over time and temperature.
    Type: Grant
    Filed: August 8, 2017
    Date of Patent: November 12, 2019

    Inventors: Roderick B. Pernites, Angel Gonzalez, Felipe Padilla Florencia
  • Patent number: 10450494
    Abstract: Cement slurries are provided for use in cementing oil and gas wells. The cement slurry comprises API Class C or Class H Portland cement and a pozzolan selected from the group consisting of pumice and mixtures of pumice and fly ash. Pumice is present in the mixtures in amounts at least about 40 wt % of the pozzolan. The weight ratio of the pozzolan to the cement is from about 35:65 to about 70:30. The novel cement slurries preferably will not comprise any additional lime, including hydrated lime, or other activators.

  • Patent number: 10087709
    Abstract: A well cementing method includes combining a spacer polymer with a liquid in a first mixer and producing a spacer polymer blend yielding a spacer pumped into a well using a product pump. The method includes combining a cement additive with the liquid in the first mixer and producing a cement additive blend yielding a wellbore cement pumped into the well following the spacer using the product pump. Another well cementing method includes combining a cement additive with a liquid in a first mixer and producing a cement additive blend. The method combines bulk cement materials and the cement additive blend in a second mixer and produces a wellbore cement pumped into a well. A well cementing system includes a liquid pump, a first mixer, an additive feeder, a second mixer separate from the first mixer, a cement feeder, and a product pump.
