Abstract
A cement composition resistant to carbon dioxide includes a hollow element for trapping carbonation products. The hollow element can be hollow spherical or quasi spherical particles including cenospheres, sodium-calcium-borosilicate glass microspheres, silica-alumina microspheres, or a combination thereof. Or the hollow element may be a spherical or quasi spherical void made in the set cement, for example by foaming the cement composition with a gas such as air, nitrogen or a combination thereof. The composition may be used to cement a subterranean well in which carbon dioxide is injected, stored or produced.
