Abstract
Cement compositions with improved mechanical properties and associated methods are provided, which are useful in conjunction with subterranean well operations. In certain embodiments, 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.
Claims16
A well bore cement composition for use in a subterranean formation comprising:
- a hydraulic cement;
- water;
- rubber particles;
- and
- carbon fibers, the carbon fibers having a mean length of about 100 microns to about 500 microns.
A well bore cement composition for use in a subterranean formation comprising:
- a hydraulic cement;
- water;
- rubber particles wherein the rubber particles have a mean length of about ¼ inch or less;
- and
- carbon fibers, the carbon fibers having a mean length of about 100 microns to about 500 microns.
A well bore cement composition for use in a subterranean formation comprising:
- a hydraulic cement wherein the hydraulic cement is a calcium phosphate cement;
- water;
- rubber particles;
- and
- carbon fibers, the carbon fibers having a mean length of about 100 microns to about 500 microns.
