Abstract
The present invention provides cement compositions with improved mechanical properties and methods of using same, which are useful in conjunction with subterranean well operations. The cement compositions comprise carbon fibers, rubber particles, a hydraulic cement material, sufficient water to form a pumpable slurry, and optionally other ingredients including a dispersant, a weighting agent, a retarding or accelerating agent, or the like.
Claims30
A method of cementing in a subterranean formation comprising the steps of:
- providing a cement composition comprising a hydraulic cement, rubber particles, and carbon fibers;
- placing the cement composition in the subterranean formation;
- and
- allowing the cement composition to set therein.
A method of increasing the tensile strength of a cement composition comprising rubber particles comprising the step of adding carbon fibers to the cement composition.
A cement composition comprising carbon fibers and rubber particles.
A cement composition comprising:
- a hydraulic cement;
- water;
- rubber particles;
- and
- carbon fibers.
A method of cementing in a subterranean formation comprising the steps of:
- providing a cement composition comprising a hydraulic cement and carbon fibers, the carbon fibers having a mean length of about 1 mm or less;
- placing the cement composition in the subterranean formation;
- and
- allowing the cement composition to set therein.
