FIELD: mining.
SUBSTANCE: group of inventions relates to mining and may be used to hydrofracture a variety of producing intervals of a subterranean formation and quantitatively monitor number of fluids produced in a variety of producing intervals of the subterranean formation. It is possible to monitor fluids produced from the hydrofractured formation by injecting fluid with an indicator into the well for hydrofracturing. The method may be used to monitor produced hydrocarbons and produced water. The indicator may be also used to protect the well against sand during hydrofracturing together with installation of a gravel pack or acid hydrofracturing of the formation. The indicator is a component of a composite where it may be immobilized in a matrix (such as an emulsion) or porous particles, on a carrier, or extruded with a binder into solid particles. The indicator may be slowly released from the composite.
EFFECT: improved efficiency of quantitative monitoring of the amount of fluids produced in a variety of hydrofractured producing intervals.
