    Abstract: The present disclosure relates to delivery and release systems, such as core-shell particles. An exemplary composition according to the disclosure can include a degradable polymeric shell surrounding a core that includes a crosslinker, which can encompass a metal, such as chromium. The core-shell particles can be provided with a gel-forming polymer, such as a polyacrylamide, into a subterranean reservoir having conditions such that the shell of the core-shell polymer degrades, and the so-released metal is effective to at least partially crosslink the gel-forming polymer to form a gel. The so-formed gel can be effective to control water flow through the subterranean reservoir, such as in relation to a waterflood of the reservoir.

  • Patent number: 11828685
    Abstract: Syntactic foams are materials including hollow microspheres distributed throughout a cured polymeric resin. Hollow microspheres within syntactic foams, including collapsible shells that enclose empty cavities, can serve as receptacles to capture environmental constituents upon applied temperature and pressure. An epoxy formulation including of EPON™ 828, HELOXY™ 61, and TETA was combined with hollow glass microspheres with isostatic crush strengths of 300, 3000, and 10,000 psi. Effects of pressure and temperature on the mechanical properties were evaluated via dynamic mechanical analysis. Storage modulus and glass transition temperature depended on formulation. Upon exposure to specific temperature and pressures, the hollow glass spheres embedded within the resin lose mechanical integrity and collapse, resulting in the generation of unencapsulated void spaces, primed to capture embedded liquid.
