Abstract:
1. 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.
