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.

Oil and gas well cement systems using elemental sulfur

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.

Pumice containing compositions for cementing a well

Improved gelled hydrocarbon fracturing fluids include a gelling agent and a crosslinking composition including a crosslinking agent and a catalytic agent. The catalytic agent is a fatty quaternized amine, which includes monoalkyl benzyl quaternized amines.
