Patent number: 8754147Abstract: A formulation and method of use for eliminating the use of hexa in shell sand encapsulation is disclosed. The composition of matter consists of standard novalac resins with the hexa component replaced by solid granular resole or curing agent. The preferred formulation and method of compounding is given. Trace elements of ammonia, phenol and the like are further reduced by the addition of a preferred 50:50 mix of an ammonia buffer and masking agent. The preferred compounds for the ammonia buffer and masking agent mix are given.Type: GrantFiled: July 8, 2010Date of Patent: June 17, 2014Assignee: Fairmount Minerals, Ltd.Inventors: Kelley J. Kerns, Robert H. Mizwicki, Ryan Schwark

Patent number: 8697185Abstract: A new device and process for continuously applying coatings, such as resin and additives or polymers or the like, to minerals are disclosed. The device and apparatus differ substantially from standard batch coating processes currently used by industry. The apparatus uses a horizontal cylinder with an internal auger and a series of injection ports distributed along the cylinder. Minerals that are to be coated are pretreated and passed through the mixing cylinder using the auger (which may comprise one or more screws with variable pitch blades). As the mineral particles pass through the cylinder various coating materials are injected by the injection ports. The complete system is described, the method of use is explained and the control system which allows for different products is described.Type: GrantFiled: October 28, 2010Date of Patent: April 15, 2014Assignee: Fairmount Minerals, Ltd.Inventors: Robert H. Mizwicki, Kelley J. Kerns

Patent number: 7647964Abstract: Described is an oil-degradable ball sealer for use in the oil and gas industry. The ball seal comprises a particular composition including ethylene and one or more alpha-olefins, prepared by an injection molding technique to provide a ball sealer which will dissolve in stimulation or wellbore fluids after stimulation operations are complete. The composition, when dissolved into wellbore fluids, does not pose a hazard or problem to aqueous wellbore fluids or further wellbore stimulations.Type: GrantFiled: December 18, 2006Date of Patent: January 19, 2010Assignee: Fairmount Minerals, Ltd.Inventors: Syed Akbar, Patrick R. Okell, A. Richard Sinclair

Patent number: 7244492Abstract: Coated particle substrates having a coating of resin and/or water soluble polymers and soluble, fibrous material are provided for use in subterranean formations. The coated particle substrate particles are typically proppants used to prop open subterranean hydrocarbon formations during recovery processes, such as after a hydraulic fracture, and provide both improved settling characteristics and improved hydrocarbon flow characteristics due to the conductive channels formed by the soluble fibers downhole. Methods of making the coated particles are also described.Type: GrantFiled: March 4, 2004Date of Patent: July 17, 2007Assignee: Fairmount Minerals, Ltd.Inventors: A. Richard Sinclair, Syed Akbar, Patrick R. Okell

Publication number: 20020058581Abstract: An aluminosilicate ceramic, spherical pellet made from spent ceramic catalyst. More specifically, a spherical ceramic pellet made from spent fluid cracking catalyst. The pellets can be made by grinding the catalyst particles, forming them into spherical pellets, and then sintering the pellets. The final product is useful as a proppant in oil and gas well fracturing.Type: ApplicationFiled: September 18, 2001Publication date: May 16, 2002Applicant: Fairmount Minerals, LtdInventors: Robert Youngman, Patrick R. Okell, Syed Akbar

Patent number: 6380138Abstract: A degradable compound, which may be used as a ball sealer and as an fluid loss additive for use in the oil and gas industry is disclosed. The compound comprises a particular composition of matter and injection molding technique that provides a ball sealer which will dissolve in stimulation or wellbore fluids after stimulation operations are complete. In a similar manner the compound may be used as a fluid loss additive which enhances the fracture filter cake and will dissolve completely after use in fracturing operations. Used as a ball sealer, the surface of the ball sealer softens slightly assuring a solid seal between the ball and the casing perforation. The pure composition when dissolved into wellbore fluids does not pose a hazard and has excellent dispersion in aqueous based wellbore fluids. The same composition, may be combined with fiber-glass to manufacture a high temperature ball sealer.Type: GrantFiled: November 22, 1999Date of Patent: April 30, 2002Assignee: Fairmount Minerals Ltd.Inventors: Noel David Ischy, Craig Steven Fox, A.
