Fluid loss control for geopolymer system

Abstract

Methods of cementing a subterranean well using a geopolymer composition are provided herein. In one aspect, the geopolymer composition can be a pumpable mixture comprising an aluminosilicate source, an activator, a carrier fluid, and a fluid loss composition comprising at least two materials selected from the group consisting of a water soluble polymer, a polymer particle dispersion, a particulate additive, and a dispersant. The geopolymer composition is placed in the subterranean well and allowed to harden into a solid geopolymer. Other methods herein include preparing a dry geopolymer slurry precursor comprising an aluminosilicate source, a metal silicate, an activator, a fluid loss control agent, and a fluid loss control agent enhancer; mixing the dry geopolymer slurry precursor with water to form a pumpable geopolymer precursor; pumping the geopolymer precursor into a subterranean well; and hardening the geopolymer precursor into a solid geopolymer within the subterranean well.
