摘要： Methods of servicing a wellbore include generating gas in a plugging composition in situ within a permeable zone in the wellbore, thereby improving the ability of the plugging composition to seal the permeable zone. The gas may be generated via a chemical reaction by, for example, introducing first and second reactants to the plugging composition that can react at ambient temperatures in the wellbore. In an embodiment, the first and second reactants are concurrently pumped into the wellbore via separate flow paths within two concentric conduits to the permeable zone where they are allowed to contact each other in the presence of the plugging composition. In another embodiment, the first reactant, the second reactant, and a retarder for slowing the reaction between the two reactants are concurrently pumped to the permeable zone. In yet another embodiment, one of the reactants is encapsulated to delay a reaction between the two reactants.

摘要： A method of servicing a wellbore that penetrates a subterranean formation includes displacing a cement composition comprising an aromatic sulfonated polymer into the wellbore and allowing the cement composition to set. In an embodiment, a transition time of the cement composition is less than or equal to about 60 minutes, alternatively less than or equal to about 50 minutes, less than or equal to about 40 minutes, less than or equal to about 30 minutes, less than or equal to about 20 minutes, or less than or equal to about 10 minutes. Thus, the transition time may be short enough to inhibit a substantial amount of gas migration into the cement composition before it sets. In yet another embodiment, the cement composition exhibits a viscosity that increases from a value of 35 Bc (Bearden units) to about 100 Bc in about 10 minutes or less when the cement composition sets.
