Publication number: 20160032175Abstract: A solid chemical delivery system for delivering chemicals to an underground. formation. The solid chemical is formed by dehydrating a silica to form anhydrous silica. Well chemicals are then introduced to the silica and form a tablet or pelletized chemical. The pelletized chemical is coated to further time-release the introduction of the chemical. The pelletized solid chemical is then delivered to the underground formation through the well bore with a proppant and fracturing fluid. This allows the well treatment chemicals to be released over time.Type: ApplicationFiled: October 13, 2015Publication date: February 4, 2016Inventors: Lewis R. Norman, Melvin B. Smith, Todd Jelinek

Patent number: 9068109Abstract: A method for the encapsulation and triggered-release of water-soluble or water-dispersible materials. The method comprises a) providing an amount of electrolyte having a charge, b) providing an amount of counterion having a valence of at least 2, c) combining the polyelectrolyte and the counterion in a solution such that the polyelectrolyte self-assembles to form aggregates, d) adding a compound to be encapsulated, and e) adding nanoparticles to the solution such that nanoparticles arrange themselves around the aggregates. Release of the encapsulated species is triggered by disassembly or deformation of the microcapsules though disruption of the charge interactions. This method is specifically useful for the controlled viscosity reduction of the fracturing fluids commonly utilized in the oil field.Type: GrantFiled: June 24, 2013Date of Patent: June 30, 2015Assignees: William Marsh Rice University, Halliburton Energy Services, Inc.Inventors: Rohit K.
