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...http://www.google.fr/patents/US5595245?utm_source=gb-gplus-shareBrevet US5595245 - Systems of injecting phenolic resin activator during subsurface fracture stimulation for enhanced oil recovery
