Abstract

Proppant compositions and methods for using same are disclosed herein. In particular, a proppant composition for use in hydraulic fracturing is disclosed herein. The proppant composition can contain a plurality of particulates and at least one particulate of the plurality of particulates containing a chemical treatment agent. The at least one particulate having a long term permeability measured in accordance with ISO 13503-5 at 7,500 psi of at least about 10 D. The at least one chemical treatment agent can separate from the at least one particulate when located inside a fracture of a subterranean formation after a period of time.

Claims12

Dependent claims

A method of diagnostic evaluation of a hydraulic fracturing stimulation of a subterranean formation, comprising:

injecting a hydraulic fluid into at least one stage of the subterranean formation at a rate and pressure sufficient to open a fracture therein, the subterranean formation comprising one or more formation fluids and the hydraulic fluid comprising a proppant composition, the proppant composition comprising porous particulates infused with a biological marker, wherein the biological marker separates from the proppant composition and returns to the surface with the formation fluids;
recovering the biological marker;
and
estimating relative hydrocarbon or water volume contribution of a stage or stages of the subterranean formation based on relative amounts of biological markers recovered from the stage or stages of the subterranean formation.
