Abstract
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.
