Patent number: 8522875Abstract: 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 14, 2012Date of Patent: September 3, 2013Assignee: Calfrac Well Services Ltd.Inventors: Timothy Tyler Leshchyshyn, Peter William Beaton, Thomas Michael Coolen

Publication number: 20130217603Abstract: The present invention relates to particles that are useful for enhancing hindered settling in suspensions. One embodiment of the present invention provides a method of providing a subterranean treatment fluid including a base fluid and a weighting agent having a first average settling velocity; and a neutral-density particle; and mixing the subterranean treatment fluid with the neutral-density particle thereby reducing the weighting agent to a second average settling velocity.Type: ApplicationFiled: February 17, 2012Publication date: August 22, 2013Applicant: Halliburton Energy Services, Inc.Inventors: Dale E. Jamison, Stephen W. Almond

Patent number: 8513166Abstract: A composition useful for crosslinking phosphate esters in hydrocarbon gels used in formation fracturing performs especially well in cold temperatures, such as temperatures lower than (?)20° C. Methods of making the crosslinking composition and the gel are described; also methods of fracturing subterranean formations. Specific forms of ferric sulfate and ferric ammonium citrate are useful as ingredients of the crosslinking composition.Type: GrantFiled: July 2, 2010Date of Patent: August 20, 2013Assignee: Conlen Surfactant Technology, Inc.Inventors: Larry W. Gatlin, Glen E. Walden, Ernest McMillan, Richard A. Gatlin

Publication number: 20130157906Abstract: A fracturing fluid, gravel pack fluid and/or frac pack fluid containing particles such as proppants, gravel and/.or sand, may contain an effective amount of a nano-sized particulate additive to fixate or reduce fines migration, where the particulate additive is an alkaline earth metal oxide, alkaline earth metal hydroxide, alkali metal oxides, alkali metal hydroxides transition metal oxides, transition metal hydroxides, post-transition metal oxides, post-transition metal hydroxides piezoelectric crystals and pyroelectric crystals. The nano-sized particulate additive is optionally bound to the particles with a coating agent such as an oil, alcohol, glycol, glycol ethers, ketones, terpenes, etc. The particle size of the magnesium oxide or other agent may be nanometer scale but may be a larger scale than nanometer but still relatively small, which scale may provide unique particle charges that help fixate the formation fines.Type: ApplicationFiled: February 20, 2013Publication date: June 20, 2013Applicant: Baker Hughes IncorporatedInventors: Tianping Huang, James B. Crews, John R. Willingham, James R. Pace, Christopher K. Belcher
