Patent number: 6770601Abstract: 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.Type: GrantFiled: February 9, 1999Date of Patent: August 3, 2004Assignee: Masi Technologies, LLCInventor: Tommy F.

Patent number: 6716797Abstract: 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.Type: GrantFiled: May 15, 2001Date of Patent: April 6, 2004Assignee: Masi Technologies, L.L.C.Inventor: Tommy F.

Patent number: 6422326Abstract: 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 40,000 centipoise.Type: GrantFiled: June 9, 2000Date of Patent: July 23, 2002Assignee: Actisystems, Inc.Inventors: Tommy F. Brookey, Roy F. House

Patent number: 6156708Abstract: Aphron-containing oil based well drilling and servicing fluids are disclosed which seal microfractures and the like during drilling and well servicing operations, thus decreasing the volume of fluid lost to the formations contacted by the fluids.. The fluids comprise an oleaginous liquid as the continuous phase, a viscosifier which imparts a low shear rate viscosity to the fluids of at least 10,000 centipoise, an aphron-generating surfactant, and aphrons. The fluids are used in a conventional method of drilling an oil and/or gas well or in conventional methods of servicing or treating such wells, such as in completion, workover, sand control, and frac pack operations, and as spotting fluids to release stuck pipes or tools in a wellbore.Type: GrantFiled: February 9, 1999Date of Patent: December 5, 2000Assignee: Actisystems, Inc.Inventors: Tommy F.
