摘要： Metal-organic frame-works (MOFs) and its compositions for use as proppants in a method of treating subterranean formations. A method comprising contacting the formation with a fluid composition comprising a metal-organic framework comprised of at least one metal ion and an organic ligand that is at least bidentate and that is bonded to the metal ion.

摘要： Methods including pumping a fracturing fluid into a subterranean formation through an annulus between the subterranean formation and a pipe conveyance at a rate above a fracture gradient of the subterranean formation to create and/or open at least one fracture in the subterranean formation; continuously pumping a proppant-free fluid into the subterranean formation through the annulus at a first rate to extend the open fracture; continuously pumping a proppant fluid through an interior of the pipe conveyance and out the exit of the interior of the pipe conveyance at a second rate that is less than the first rate; and placing the proppant particulates into a portion of a fracture in the subterranean formation so as to form a proppant pack having proppant-free channels therein.

摘要： Methods of creating variably tacky proppants and providing such proppants into a subterranean formation are provided. The variably tacky proppants can be non-tacky at a first set of conditions and tacky at a second set of conditions. As such, the variably tacky proppants can be pumped into a subterranean formation and caused to enter fractures in the formation while the proppants are non-tacky. Subsequently, natural or induced conditions in the well bore can cause the proppants to become tacky. The tacky proppants inhibit the movement of proppants in the fractures when pressure is reduced in the formation and inhibit the migration of fines towards the wellbore.
