Abstract
Methods for heating a material within a wellbore using nano-particles such as carbon nano-tubes. The material may be a flowable material such as cement, drilling mud, an acidizing fluid, or other material. Generally the methods comprise placing the flowable material in proximity to a radial wall of a wellbore. The methods also include running an energy generator into the wellbore. In one aspect, energizing the nano-particles in the filter cake causes the nano-particles to be activated, and increases a temperature within the flowable material to a temperature that is greater than an initial circulation temperature of the flowable material. Activating the energy generator may also assist in curing the flowable material in situ.
