For lost circulation treatment for decreasing fluid loss from a borehole into a subterranean formation, a lost circulation additive including water soluble crosslinkable polymer, a crosslinking agent, a filter aid that is preferably diatomaceous earth, and optionally a reinforcing material. The method of forming a lost circulation fluid includes contacting the additive with water or an aqueous solution, with a method of lost circulation treatment of the formation further including the step of injecting the fluid into the formation thereby decreasing fluid loss from the borehole into the subterranean formation.
