Abstract: The present disclosure relates to delivery and release compositions, systems, and methods of use thereof. In particular, the present disclosure relates to degradable polymeric systems including a first epoxy-containing monomer and a second, different epoxy-containing monomer, wherein the degradable polymeric system is crosslinked, and wherein one of the first epoxy-containing monomer and the second, different epoxy-containing monomer includes one or more ester groups; delivery systems incorporating degradable polymeric systems; and methods for providing cargo to a petroleum reservoir.

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.

Abstract: The present disclosure relates to delivery and release systems wherein a plurality of particles is provided, and the particles are formed of a vehicle component and a cargo component. The systems and methods particularly can be useful in delivery of various chemicals to a petroleum reservoir. The vehicle component can undergo a change in situ such that at least a portion of the cargo component is released.
