Patent number: 8211834Abstract: The invention describes improved fracturing compositions, methods of preparing fracturing compositions and methods of use. Importantly, the subject invention overcomes problems in the use of mists as an effective fracturing composition particularly having regard to the ability of a mist to transport an effective volume of proppant into a formation. As a result, the subject technologies provide an effective economic solution to using high ratio gas fracturing compositions that can be produced in a continuous (i.e. non-batch) process without the attendant capital and operating costs of current pure gas fracturing equipment.Type: GrantFiled: June 16, 2009Date of Patent: July 3, 2012Assignee: Calfrac Well Services Ltd.Inventors: Timothy Tyler Leshchyshyn, Peter William Beaton, Thomas Michael Coolen

Patent number: 8201630Abstract: Method of treating a subterranean formation using a hydrocarbon treatment fluid using a phosphor-based hydrocarbon gelling agent that is capable of both increasing the viscosity of the hydrocarbon treatment fluid and remaining in the subterranean formation after the viscosity of the gel is broken such that it can act as a scale inhibitor. Phosphor-based hydrocarbon gelling agents may be formed from a polyvalent metal salt of an organophosphonic acid ester or from a polyvalent metal salt of an organophosphinic acid.Type: GrantFiled: October 29, 2009Date of Patent: June 19, 2012Assignee: Halliburton Energy Services, Inc.Inventor: Thomas D.

Patent number: 8176981Abstract: A composition comprising a nonionic fluorinated polymeric surfactant having a weight average molecular weight of least 100,000 grams per mole, the nonionic fluorinated polymeric surfactant comprising: divalent units independently represented by formula (I): in a range from 30% to 65% by weight, based on the total weight of the nonionic fluorinated polymeric surfactant; and divalent units independently represented by formula (II): in a range from 70% to 35% by weight, based on the total weight of the nonionic fluorinated polymeric surfactant. Rf is a perfluoroalkyl group having from 3 to 4 carbon atoms; R and R2 are each independently hydrogen or alkyl of 1 to 4 carbon atoms; R1 is alkyl of 16 to 24 carbon atoms; and n is an integer from 2 to 11. Foams comprising the nonionic fluorinated polymeric surfactant and a liquid hydrocarbon and methods of making and using the foams are also disclosed.Type: GrantFiled: January 18, 2008Date of Patent: May 15, 2012Assignee: 3M Innovative Properties CompanyInventors: Patricia M. Savu, Michael J. Sierakowski

Patent number: 8119575Abstract: Among other things, methods of treating a subterranean formation with gelled hydrocarbon fluids are provided. In certain embodiments, these methods comprise the steps of providing a gelled liquid hydrocarbon treatment fluid comprising a liquid hydrocarbon and a gelling agent that comprises a polyvalent metal salt of an organophosphonic acid ester or a polyvalent metal salt of an organophosphinic acid, and treating the subterranean formation with the gelled liquid hydrocarbon treatment fluid. The gelled liquid hydrocarbon treatment fluids of the present invention are suitable for use in subterranean treatment operations, such as subterranean stimulation and sand control treatments like fracturing and gravel packing, that may be carried out in subterranean formations for the production of hydrocarbons.Type: GrantFiled: January 25, 2008Date of Patent: February 21, 2012Assignee: Halliburton Energy Services, Inc.Inventors: Robert S. Taylor, Gary P. Funkhouser, Michael A. McCabe, B. Raghava Reddy

Patent number: 7932216Abstract: A substantially liquid gellant formed as one or more reaction products of a metal carboxylate or metal carboxylate amine salt, one or more organic acids, an ester which drives the reaction so that the reaction products are asymmetrical in structure, and a rheology modifier which preferentially interacts between the reaction products for prevent solidifying of the gellant reaction products until such time as the gellant is mixed with the fracturing fluid containing an activator after which the reaction products preferentially interact with the activator to gel the fracturing fluid. The resulting gellant is capable of gelling a hydrocarbon base fluid in less than about 30 seconds.Type: GrantFiled: December 14, 2007Date of Patent: April 26, 2011Assignee: Weatherford Engineered Chemistry Canada LtdInventors: Clayton Smith, Simon John Michael Levey
