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. Brookey

Patent number: 6649571Abstract: Disclosed is a method of generating microbubbles in oleaginous liquids which comprises adding a silicone oil to the oleaginous liquid and thereafter subjecting the liquid to mechanical forces in the presence of a gas. Also disclosed are oil base well drilling and servicing fluids having a low shear rate viscosity as measured with a Brookfield Viscometer at 0.5 rpm of at least 10,000 centipoise and having incorporated therein microbubbles generated by the disclosed method, and a method of drilling a well wherein there is circulated within the wellbore during drilling the oil base, microbubble-containing fluid disclosed.Type: GrantFiled: April 4, 2000Date of Patent: November 18, 2003Assignee: Masi Technologies, L.L.C.Inventor: Julie Benedetta Maria Aline Morgan
