NOVELTY - Cementing a subterranean well involves preparing a cement composition comprising an aqueous fluid, inorganic cement, a foaming agent, a gas generating agent and a stabilizer composition comprising graphene oxide, placing the cement composition in a subterranean well and allowing the composition to set and form a set cement. The presence of the graphene oxide results in the set cement having a greatest percent deviation from a measured slurry density of less than or equal to 1.5%. USE - Cementing subterranean well. ADVANTAGE - The method uses reduced density of the cement with excellent compressive strength and improved permeability, thus preventing hydrostatic pressure damage. The cement composition provides excellent flexibility such that the set cement is both compressible and expandable.
