Claim 15:
16. A method of cementing a well during drilling operations comprising:
drilling a section of the well in a formation;
lowering a section of casing into the drilled section of the well;
pumping down through the casing and up and around the casing into an annulus between the casing and the formation, a cement composition comprising cement aggregate, water, and a triggerable gel composition having an untriggered size, and comprising a polymer, wherein the polymer comprises an inert monomer, a practical monomer, and less than 1.5% by weight of a cross-linker, and wherein once the cement composition is cured it forms a solid cement composition; and
wherein, when a leakage pathway forms in the solid cement composition, the triggerable gel composition is exposed to at least one of carbonic acid and sulfuric acid and thereby swells to at least ten times the untriggered size and forms a permanent seal within the leakage pathway with carbonate materials.
