Jet pump lift system for producing hydrocarbon fluids

Abstract

A jet pump lift system for use with a tubing disposed in a casing includes a jet pump installed in the tubing; a one way valve for communicating a power fluid into the jet pump; and a safety valve configured to block fluid communication through the tubing and disposed above the jet pump.

1 . A jet pump lift system for use with a tubing disposed in a casing, comprising:
 a jet pump installed in the tubing;   a one way valve for communicating a power fluid into the jet pump; and   a safety valve configured to block fluid communication through the tubing and disposed above the jet pump.   
     
     
         2 . The system of  claim 1 , wherein the one way valve comprises a check valve. 
     
     
         3 . The system of  claim 1 , wherein the safety valve comprises a flapper valve. 
     
     
         4 . The system of  claim 1 , wherein the one way valve allows fluid communication from an annular area between the tubing and the casing to the jet pump. 
     
     
         5 . The system of  claim 1 , wherein the one way valve is positioned below the safety valve. 
     
     
         6 . The system of  claim 1 , wherein the safety valve is positioned at a depth of 3,000 ft. or less. 
     
     
         7 . The system of  claim 6 , wherein the one way valve is positioned at a depth of 6,000 ft. or more. 
     
     
         8 . The system of  claim 1 , wherein the one way valve is positioned at a depth of 6,000 ft. or more. 
     
     
         9 . The system of  claim 1 , further comprising an annular packer located below the one way valve. 
     
     
         10 . The system of  claim 1 , wherein the one way valve is installed in a side pocket of the tubing. 
     
     
         11 . A method of producing hydrocarbon fluids, comprising;
 installing a jet pump in a production tubular;   maintaining a safety valve located above the jet pump in an open position;   supplying a power fluid through a one way valve and into the jet pump;   urging a production fluid into the jet pump; and   flowing the production fluid and the power fluid past the safety valve.   
     
     
         12 . The method of  claim 11 , wherein the production tubular is disposed in a casing, and the power fluid is supplied down an annular area between the production tubular and the casing. 
     
     
         13 . The method of  claim 12 , wherein the one way valve controls power fluid flow into the production tubular. 
     
     
         14 . The method of  claim 11 , wherein the power fluid flows into the jet pump via a side port. 
     
     
         15 . The method of  claim 11 , wherein the safety valve comprises a flapper valve. 
     
     
         16 . The method of  claim 11 , wherein the one way valve comprises a check valve. 
     
     
         17 . The method of  claim 11 , wherein the safety valve is located a depth of 3,000 ft. or less.
