Radiation activated well treatment

A method of treating a wellbore or a hydrocarbon formation, comprising:

• introducing a well treatment composition comprising a treatment agent solution encapsulated within a polymer shell downhole to a target location in a delivery fluid comprising wellbore circulation fluid,
• wherein the treatment agent solution comprises a treatment agent and an emulsion comprising one or more selected from the group consisting of an oil-in-water emulsion, a water-in-oil emulsion, a water-in-oil-in-water emulsion, and an oil-in-ater-in-oil emulsion, and wherein the emulsion includes an internal phase comprising the treatment agent;
• and
• wherein the polymer shell comprises one or more selected from the group consisting of melamine-formaldehyde, an urea-formaldehyde, a phenol-formaldehyde resin, a melamine-phenol-formaldehyde resin, a furan-formaldehyde resin, an epoxy resin, a polysiloxane, a polyurethane, a polyether, a polyimide, a polyolefin, a gelatin, a gelatin derivative, a starch, a starch derivative, an ethylene-vinylacetate copolymer, a maleic-anhydride based copolymer, a polyacrylamide, a polyacrylamide based copolymer, a polyvinylpyrrolidone, a polyvinylpyrrolidone based copolymer, a propylene-acrylate copolymer, a propylene-methacrylate copolymers, an oxidized polypropylene, an oxidized polyethylene, a propylene-ethylene oxide copolymer, a styrene-acrylate copolymer, and an acrylonitrile-butadiene-styrene copolymer;
• introducing a radiation source into the wellbore and positioning the radiation source at the target location;
• activating the radiation source and emitting radiation that intimately intermingles with the well treatment composition at the target location, wherein the emitted radiation is one or more selected from the group consisting of neutron, gamma, X-ray, ultraviolet (UV), and a combination thereof;
• maintaining the wellbore to allow emitted radiation from the activated radiation source to react with the well treatment composition, thereby forming a radiation activated well treatment composition;
• and
• allowing the radiation activated well treatment composition to disintegrate or dissolve, thereby degrading the polymer shell, breaking encapsulation and releasing treatment agent at the target location.
