  • Oil and gas well cement systems using elemental sulfur
    Patent number: 8596363
    Abstract: A cement composition for cementing an oil or gas well includes Portland cement, water and a sulfur component. The cement composition may be used to cement a well bore by creating a cement slurry including the sulfur component, pumping the slurry into the well bore to a selected location and allowing it to solidify.

  • Pumice containing compositions for cementing a well
    Patent number: 7867954
    Abstract: A cement composition comprises fine pumice particles, for use in cementing subterranean wells, and oil and gas wells in particular. The pumice containing cement blends feature enhanced compressive strength, and favorable compressive strength to Young's Modulus ratios. Lightweight cement blends containing pumice, and their use in cementing oil and gas wells are also described.
