ABSTRACT:
The disclosed invention is a method for reducing lost circulation in wellbores. In the method, a liquidized sand, comprised of a particulate material, a resin, and a carrier fluid comprising a surfactant mixed with air, is injected into the wellbore. The liquidized sand is then allowed to solidify in the lost circulation area, thereby sealing the area and reducing or eliminating the lost circulation.
