Abstract
The invention provides geopolymeric compositions intended for use in carbon dioxide injection or production wells or storage reservoirs and preferably in a supercritical carbon dioxide conditions. The geopolymeric composition is formed from a suspension comprising an aluminosilicate source, a metal silicate, an alkali activator, a retarder and/or an accelerator and a carrier fluid wherein the oxide molar ratio M2O/SiO2 is greater than 0.20 with M an alkali metal.
