Abstract
A method of sequestering at least one target species, including exposing a proppant for use in subterranean hydrocarbon recovery via hydraulic fracturing which comprises a material adapted to sequester the at least one target species formed external to the subterranean formation and formed external to the proppant and the material, at least one of (a) prior to injecting a fluid comprising the proppant into a subterranean fracture or (b) subsequent to injecting the fluid comprising the proppant into the subterranean fracture; or exposing the material of the proppant to the at least one target species prior to completing formation of the proppant.

A method of sequestering at least one target species, comprising:
- (i) exposing a proppant for use in subterranean hydrocarbon recovery via hydraulic fracturing which comprises a material adapted to sequester the at least one target species formed external to a subterranean formation and formed external to the proppant and the material, at least one of (a) prior to injecting a fluid comprising the proppant into a subterranean fracture or (b) subsequent to injecting the fluid comprising the proppant into the subterranean fracture;
- or
- (ii) exposing the material of the proppant to the at least one target species prior to completing formation of the proppant.
A proppant for use in hydraulic fracturing in a subterranean formation to prop a fracture therein, comprising a material adapted to sequester at least one target species formed external to the subterranean formation and formed external to the proppant and the material.
