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. 本文公开了支撑剂组合物及其使用方法。特别地，本文公开了用于水力压裂的支撑剂组合物。支撑剂组合物可以包含多个微粒，并且所述多个微粒中的至少个微粒包含化学处理剂。所述至少个微粒具有至少约10D的在7,500psi下按照ISO 13503-5测得的长期渗透率。所述至少种化学处理剂当位于地下岩层的裂缝内部段时间后可以与所述至少个微粒分离。
