  • Hydrogels derived from acrylamide for controlling circulation losses and methods of fabrication thereof
    Patent number: 11787909
    Abstract: Acrylamide-derived hydrogels and methods of fabrication thereof from an acrylic monomer, a crosslinking agent comprising an organosilicon compound, a polymerization initiator, a solvent and a polymerization accelerator, as well as their use in controlling circulation losses. The obtained hydrogels interact with the walls of the reservoir and exhibits an increase in viscosity, either at delayed times or in response to a given stimulus, such as changes in temperature, pressure, pH, salinity, using a simple and easily scalable methodology.
    Type: Grant
    Filed: December 23, 2019
    Date of Patent: October 17, 2023
    Assignees: YPF TECNOLOGIA S.A., UNIVERSIDAD DE BUENOS AIRES, CONSEJO NACIONAL DE INVESTIGACIONES CIENTIFICAS Y TECNICAS (CONICET).
