Abstract
The present invention discusses methods for making a cement composition comprising a nanoparticle zeolite. The addition of the nanoparticle zeolite may provide enhanced compressive and tensile strengths, improved rheology, and a change to the cement microstructure. These effects may improve the cement's use as a cement sheath in drilling operations and under high pressure and high temperature (HPHT) conditions.
