Abstract
Heatable wellbore material, e.g., cements, polymers, composites, and epoxies, and systems and methods using heatable material, which, in certain aspects, are methods for cementing casing in a wellbore with such cement, the heatable material, in some aspects, being one or a combination of electrically resistively heatable material, microwave heatable material, and/or material heatable by the application thereto of a magnetic field.
Claims8
A method comprising
- making a wellbore in the earth,
- placing a tubular string in the wellbore,
- introducing cement into a space between an exterior of the tubular string and an interior of the wellbore, the cement containing heatable material,
- allowing the cement to set,
- facilitating setting of the cement with heat, the heat generated by applying energy to the heatable material thereby heating the heatable material,
- wherein the heatable material is at least one of or a combination of nanotubes, nanographene, nanographene ribbons, transformed nanomaterials, carbon nanomaterials, carbon nanotubes, single-walled nanotubes, multi-walled nanotubes, double walled nanotubes, and surface-modified nanotubes.
