Patent ID: 7870903

Claim:
A method of servicing a wellbore that penetrates a subterranean formation comprising: placing a sealant composition comprising an inverse emulsion polymer into the wellbore at a pressure insufficient to initiate or extend a fracture within the subterranean formation to reduce a loss of fluid to the subterranean formation during placement of the fluid in the wellbore, wherein the inverse emulsion polymer comprises from about 10 wt. % to about 80 wt. % oil by total weight of the inverse emulsion polymer, wherein the inverse emulsion polymer comprises from about 0 wt. % to about 70 wt. % water by total weight of the inverse emulsion polymer, wherein the inverse emulsion polymer has a pH of from about 5.1 to about 8, and wherein the inverse emulsion polymer is dehydrated prior to placement in the wellbore to comprise from about 0 wt. % to about 10 wt. % water.
