Abstract
The invention provides a cement slurry composition for cementing a well comprising a hydraulic cement, water, carbon fiber and graphite. Compositions of the current invention combine the benefits obtained from adding carbon fiber and graphite to the cement composite. The synergy achieved from combining fibers and particulates into the same sample results in a composite slurry with improved electrical properties and easy-to-optimize rheologies.
