PROPPANT FLOWBACK CONTROL USING ENCAPSULATED ADHESIVE MATERIALS

摘要

The present Invention relates generally to the field of petroleum production. More specifically, the present Invention relates to a method for stimulation of reservoirs for fluid production. A method of treating a subterranean formation includes the initial stage, wherein a fracture is propped with a conventional proppant mixed with an encapsulated tackifying (adhesive) compound. The amount of encapsulated tackifying compound preferably varies from about 0.01 to about 20 weight per cent relative to the proppant. An encapsulated adhesive compound and proppant may be pre-mixed or a mixture may be prepared on the fly at the well site and than introduced into the subterranean formation. A second stage includes fracture closure that leads to capsule breakage and release of the adhesive compound.
