CONTINUOUS RECIRCULATION FOR SEPARATION OF FLUIDS PRODUCED DURING DRILL OUT AND FLOW BACK

Abstract: one or two continuous recirculation loops are utilized for the well-site equipment that separates produced fluids into sand, liquid, and gas during drill out and flow back that occurs after fracturing a subterranean formation. when one recirculation loop is utilized, the recirculation loop continuously recirculates fluid between the recirculation chamber of the disclosed sand removal apparatus and a shaker device. when two recirculation loops are utilized, the first recirculation loop continuously recirculates fluid between a recirculation chamber of the disclosed sand removal apparatus and a shaker device, and the second recirculation loop continuously recirculates fluid between the recirculation chamber and a gas separator.
