The permeability recovery phase begins with pack-width measurements, temperature conditioning of ,flowback fluid, and injection of 2% KCl (aq) ,flowback fluid, into the cell. Aqueous ,flowback, is initiated at a rate of 3.00 mL/min by flowing laterally through the proppant-pack while closure stress is raised to final closure stress (3000psi) at 100 psi/min. Permeability is monitored for cell inlet ...
