LOST CIRCULATION COMPOSITIONS AND METHODS OF USING THEM

摘要

A lost circulation composition for use in a wellbore comprising a crosslinkable polymer system and a filler. The invention also relates to a method of servicing a wellbore in contact with a subterranean formation, comprising: placing a wellbore servicing fluid comprising a crosslinkable polymer system and a filler into a lost circulation zone within the wellbore. The invention also relates to a method of blocking the flow of fluid through a lost circulation zone in a subterranean formation comprising placing a first composition comprising a packing agent into the lost circulation zone, placing a second composition comprising a crosslinkable polymer system and a filler into the lost circulation zone, and allowing the compositions to set into place.
