Patent ID: 8424599

Claim:
A method of separating and controlling the flow of fluids in an oil and gas well system, the method comprising the steps of: a) routing the flow of fluids to a filter to remove solid materials from the fluid; b) routing the flow of fluids from the filter to one or more blast choke barrels, each blast choke barrel comprising an outer chamber; and a primary barrelhead adjustably affixed inside the outer chamber, wherein the primary barrelhead comprises at least one nipple, at least one choke, wherein the at least one nipple and at least one choke are exposed for maintenance by rotating the chamber from the primary barrelhead without dismantling the at least one blast barrel from connected high pressure lines; c) monitoring fluid pressures in predetermined locations by sensors in the one or more blast choke barrels; d) automatically adjusting the flow of fluids through the one or more blast choke barrels by a controller based on the monitored pressures; e) routing the flow of fluids from the one or more blast choke barrels to a closed loop separation tank; and f) separating the flow of fluids into a remaining solid material, produced water, produced oil, and gas.
