Abstract
Embodiments relate to preparation of expandable particulates and their use in fracturing operations. An embodiment provides a method for treating a subterranean formation comprising: introducing a treatment fluid comprising expandable particulates into the subterranean formation, wherein the expandable particulates each comprise a particulate substrate, a swellable material coating the particulate substrate, and an exterior coating comprising a resin; and depositing at least a portion of the expandable particulates in the subterranean formation.
Claims13
A method of treating a subterranean formation comprising:
- introducing a treatment fluid comprising expandable particulates into a wellbore penetrating a subterranean formation, wherein the expandable particulates each comprise a particulate substrate, a swellable material coating the particulate substrate, and an exterior coating comprising a cured resin, wherein the exterior coating comprises one or more access paths to allow fluid entry to the swellable material beneath the resin;
- depositing at least a portion of the expandable particulates in the subterranean formation such that a proppant pack comprising the portion of the expandable particulates is formed in one or more fractures in the subterranean formation, wherein the one or more access paths being formed after the expandable particulates are deposited in the subterranean formation;
- and
- allowing a fluid to enter the one or more access parts and contact the swellable material.
