ABSTRACT:
An apparatus for controlling flow from a producing zone through a tubing string and through a bypass into the annulus between the tubing string and casing, the apparatus including a production flow tube and bypass tube extending through a packer which is set by fluid pressure supplied through the tubing string. A safety valve and sleeve assembly is positioned by wire line after the packer is set, the sleeve including a bypass control valve. The tubing string may carry a pump and electric motor and the bypass may receive encased conductors for the motor. The safety valve sleeve assembly includes fluid pressure responsive means for holding the safety valve in its open position, and a small pressure fluid line extends to the well mouth. Drop in pressure in the fluid line, either by control at the well mouth or by damage to the pressure fluid line, permits a spring to close the safety valve against upward flow of well fluid, and also to close the bypass control valve.
