Abstract
Methods and compositions for treating subterranean formations to mitigate lost circulation are provided. The methods of the present disclosure include forming a treatment fluid including one or more geopolymer lost circulation materials; introducing the treatment fluid into at least a portion of a subterranean formation that includes at least one loss zone; activating the geopolymer lost circulation materials to form a geopolymer that imparts a thixotropic property to the treatment fluid; and allowing the treatment fluid exhibiting the thixotropic property to at least partially reduce a rate of loss associated with the loss zone.
