ABSTRACT:
In connection with downhole placement of proppant materials for the purpose of enhancing oil recovery through a subsurface fracture-stimulation treatment, phenolic resin activator is injected after resin-coated proppant is pumped. The results are a reduced probability of problems attendant to premature screenout, savings in the quantity of activator needed, more concentrated placement of the activator close to the wellbore, and the ability to continue the fracturing treatment longer. Injection of activator is accomplished through tubing extending at least as deep as the perforations, while injection of proppant is done through the tubing-casing annulus.
