Abstract:
A method and drilling fluid additive for reducing severe fluid losses in a well, comprising a combination of granular scrap tire particles and polymer adhesive molded into a cone shape. Once in the severe loss zone, a plurality of LCMs wedge into the formation fractures and seal off the severe loss zone.

Claim (Index 1):
A method of reducing lost circulation in a severe loss zone of a wellbore, the method comprising:\n introducing a drilling fluid comprising a liquid carrier, a weighting material and a plurality of additives into the severe loss zone such that the plurality of additives become lodged in at least one fracture that defines the severe loss zone, the plurality of additives comprising cone-shaped LCMs comprising:\n a plurality of granular scrap tire particles; and \n a polymer adhesive that is dispersed between the plurality of granular scrap tire particles and binds the plurality of granular scrap tire particles together.
