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 viscosifier which increases the low shear rate viscosity of the fluid to at least 10,000 centipoise, an aphron-generating surfactant, and aphrons, wherein the fluid contains less than about 20% 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 re-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 crosslinked polysaccharide gels that are crosslink 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 crosslinkable polysaccharide and a crosslinking 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 crosslink.

摘要： The invention provides a method and fluid for drilling or servicing a well in a subterranean formation, particularly containing lost circulation zones or depleted, low pressure reservoirs. A method of decreasing the density of the fluid circulated in a borehole, decreasing the invasion of fluid into formations contacted by the fluid, or decreasing the lost circulation potential of the fluid is provided by using as the fluid an aqueous liquid having dispersed therein a polymer which increases the low shear rate viscosity of the fluid to the extent that the shear thinning index of the fluid is at least about 10, a surfactant, and aphrons, wherein the aphrons are preferably generated by the turbulence and pressure drop as the fluid exits the drill bit in the vicinity of the formation, the fluid having a low shear rate viscosity of at least 10,000 centipoise. The fluid additionally contains an oligosaccharide mixture composed of pentosans and/or hexosans containing from one to about 10 combined sugar units selected from the group consisting of arabinose, mannose, galactose, glucose, xylose, cellobiose, and mixtures thereof. Preferably the oligosaccharide mixture is the water soluble portion of thermally hydrolyzed lignocellulose.
