Claim 0:
1. A method for performing a sealing operation in a wellbore comprising:
introducing a sealant composition into the wellbore while the sealant composition is under shear, the sealant composition comprising:
a thixotropic material,
a conformance gel system, and
an aqueous base fluid;

placing the sealant composition into a target location, wherein the target location is an annulus of the wellbore; wherein the annulus is adjacent to a water zone of a subterranean formation;
reducing shear applied to the sealant composition when in the target location thereby allowing the sealant composition to thicken in the target location, and
reducing fluid flow across the target location with a fluid seal formed by the thickened sealant composition; thereby reducing water flow into the annulus from the water zone.
