Abstract
A submersible pump system for petroleum production in which the pump is suspended from an H-member with production passing up one leg of the H-member and gas passing up the other leg of the H-member. Valve means provide for alternately directing the liquid in a recirculating path through the H-member to the pump while closing in gas flow and closing the cross-member in the H-member and providing for gas and liquid flow through the separate legs of the H-member. The system is coordinated with a subsurface safety valve in the tubing above the H-member and the valve means and subsurface safety valve are controlled by the same pressure line.
