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.
