摘要： The invention provides a method and fluid for drilling or servicing a well in a subterranean formation containing lost circulation zones or depleted, low pressure reservoirs. The fluid comprises an aqueous liquid having dispersed therein a polymer which increases the low shear rate viscosity of the fluid to the extent that the thixotropic index of the fluid is at least about 10 and a surfactant, and wherein the fluid contains less than about 15 % by volume of aphrons preferably generated by the turbulence and pressure drop as the fluid exits the drill bit in the vicinity of the formation. The method of drilling a wellbore in a subterranean formation comprises continuously circulating, while drilling, such a drilling fluid.

摘要： Permeable subterranean underground formations and fractures can be sealed using lost circulating material fluids having borate and metallic cross-linked polysaccharide gels that are cross-linked in the well bore. Compositions and methods are illustrated whereby lost circulation material solids can be mixed in a mixing tank on the surface with a cross-linkable polysaccharide and a cross-linking agent under conditions whereby the lost circulating material fluid can be pumped into the well bore before undergoing gelation. Once the lost circulation material fluid equilibrates to the reservoir temperature the polysaccharide component of the lost circulation material fluid will cross-link.
