Abstract:
Portland cement clinker LCMs that include Portland cement clinker to mitigate or prevent lost circulation in a well are provided. A Portland cement clinker LCM may include Portland cement clinker, Portland cement, a carrier fluid, and an inorganic consolidation activator. Another Portland cement clinker LCM may include Portland cement clinker and a crosslinked fluid, such as a polyuronide crosslinked via calcium ions or a polysaccharide crosslinked via divinyl sulfone. Yet another Portland cement clinker LCM may include Portland cement clinker and polymer fibers or particulate glass. Methods of lost circulation control using a Portland cement clinker LCM are also provided.

Claim (Index 1):
A lost circulation material (LCM) composition, comprising:\n Portland cement clinker, wherein the Portland cement clinker consists of non-hydraulic, non-cementiceous unground Portland cement clinker particles; cement, wherein the cement comprises API Class G cement; a carrier fluid; and an inorganic consolidation activator selected to consolidate the clinker in the composition to form a plug when introduced into a lost circulation zone.
