Patent number: 9856414Abstract: Compositions, systems and methods for the prevention or reduction of clumping or sticking of particulate hydraulic fracturing chemical additives. In preferred examples the particulate hydraulic fracturing chemical additives may be coated with, for example, a coating comprising a polymeric component and with or without silica. Inorganic flow agents (IFA) may be applied to the exterior surface of the particulate hydraulic fracturing chemical additives to prevent hardening or clumping of the additives upon storage. Preferably the coating is permeable, but insoluble in an aqueous medium, whereupon the additive components are released into the medium.Type: GrantFiled: May 6, 2014Date of Patent: January 2, 2018Assignee: DOBER CHEMICAL CORP.Inventors: Magesh Sundaram, Stephen Mosher, Joseph Yaritz

Publication number: 20130255951Abstract: Compositions, systems and methods for the controlled and/or delayed release of chemical additive components into an aqueous fluid used in hydraulic fracturing of oil and/or gas wells. The chemical additive components may include a viscosity-reducing composition, an oxidizer composition, a pH modulating composition, a lubricant composition, a cross-linking composition, an anti-corrosion composition, an biocide composition, a crosslink-enhancing composition, and/or a combination of two or more of these compositions. Further embodiments include additives and methods of delivering a particle comprising an additive component to a desired site in an aqueous medium prior to release of the additive component into the aqueous medium. The coating is permeable, but insoluble in an aqueous medium, whereupon the additive components are released into the medium.Type: ApplicationFiled: February 19, 2013Publication date: October 3, 2013Applicant: DOBER CHEMICAL CORPORATIONInventors: David Alan Little, Magesh Sundaram
