摘要 A method of servicing a wellbore, comprising preparing a sealant composition comprising a crosslinkable material, a crosslinking agent, a fluid loss control additive, and water, placing the sealant composition in a permeable zone in the wellbore, and allowing the sealant composition to set. A method of servicing a wellbore, comprising preparing a sealant composition by combining a crosslinkable material, a crosslinking agent, a fluid loss control additive, water, and a cement, wherein an amount of the cement is reduced to an effective amount to increase a gel time of the sealant composition to greater than or equal to about 4 hours when the sealant composition is exposed to ambient temperatures in the wellbore, placing the sealant composition in a permeable zone in the wellbore, and allowing the sealant composition to gel.
