Abstract: An encapsulated agent includes a central part and an outer part that covers a surface of the central part. The central part contains a viscosity-reducing material that reduces viscosity of a fluid to be used in a hydrofracturing technique. The outer part contains a plurality of particulate substances and a holding material that holds the plurality of particulate substances and enables gradual release of the central part in the fluid. The outer part involves distribution of the plurality of particulate substances that allows a content to have one or more local maxima in a direction away from the central part.

Abstract: An encapsulated agent includes a central part and an outer part that covers a surface of the central part. The central part contains a material that is expansive with respect to a liquid, and the outer part contains a material that is able to induce expansion of the central part with respect to the liquid.

Abstract: A carrier system carries at least one type of sensitizing dye described in (A) and at least one type of sensitizing dye described in (B): (A) a sensitizing dye having a π-conjugated group and at least one anchor group, wherein the π-conjugated group and every one of the anchor group(s) are connected by a spacer having at least one alkylene and having an atomicity of 5 to 20; and (B) a sensitizing dye having a π-conjugated group and at least one anchor group, wherein the π-conjugated group and at least one anchor group are connected by a direct bond or by a spacer having at least one alkylene and having an atomicity of 1 to 4. In (A) and (B), the spacer is composed of carbon atoms, or carbon atoms and oxygen atom(s) etc., under predetermined conditions (see Description), and may have a branched chain or a ring structure.

Abstract: An encapsulated agent includes: a central part 1; and an outer part 2 that covers a surface of the central part 1. The central part 1 contains a viscosity-reducing material that reduces the viscosity of a fluid to be used in a hydrofracturing technique. The outer part 2 enables gradual release of the central part 1 in the fluid, and contains a styrene-butadiene copolymer having glass-transition temperature that is equal to or higher than −20 degrees centigrade and equal to or lower than 80 degrees centigrade.
