A method and apparatus for inserting a small diameter continuous hydraulic conduit or capillary tube down a well bore is presented. The methods and apparatus allow either the injection of chemicals to enhance production of oil and gas, or to provide a conduit for production up through the small diameter tubing in marginal wells, into a hanger below a well valve to permit its removal from below the valve if the valve should be required to be closed and its reinsertion without pulling the tubing from the well bore.

The method of claim 3 further comprising deploying a third hydraulic conduit, the third hydraulic conduit configured to hydraulically operate the extraction device. 12. The method of claim 3, wherein the second hydraulic conduit is sealingly engaged with the first hydraulic conduit when the stinger is engaged within the bore receptacle. 13. The method of claim 12 wherein the second hydraulic conduit includes a valve along its length. 14.

The method of claim 13 wherein the valve is a gas lift valve. 16. The method of claim 1 wherein the deploying of the first hydraulic conduit is performed through production tubing. 17. The method of claim 3 further comprising increasing a hydraulic pressure on the extraction device to pass the first hydraulic conduit through the well valve. 18. The method of claim 3 further comprising retracting the stinger in stages with the extraction device. 19. The method of claim 2 wherein the well valve is a safety valve. 20. The method of claim 19 wherein the safety valve is configured to close in the event of a loss of pressure. 21. The method of claim 3 further comprising: extracting the first hydraulic conduit from the well valve when the well valve is in an open state; closing the well valve; bleeding well pressure from the wellbore; and monitoring the integrity of the well valve. 22. The method of claim 21 comprising injecting fluids down the first hydraulic conduit and out its distal end above the closed well valve. 23. The method of claim 21 further comprising producing fluids from a well via the first hydraulic conduit when the stinger is positioned above the closed well valve. 24. The method of claim 2 further comprising: inserting the first hydraulic conduit through the well valve until the stinger of the first hydraulic conduit seats in the bore receptacle; and pumping fluid through the first hydraulic conduit. 25. The method of claim 24, wherein the second hydraulic conduit is sealingly engaged with the first hydraulic conduit when the stinger is engaged within the bore receptacle. 26. The method of claim 25 further comprising pumping fluids from the first hydraulic conduit, through the bore receptacle, through the second hydraulic conduit, and into the wellbore. 27. A method for selectively communicating hydraulically from a surface location to a location below a valve within a wellbore, the method comprising: positioning and setting a bore receptacle in the wellbore, the wellbore having a valve placed therein; deploying a first hydraulic conduit into the wellbore, the first hydraulic conduit having an upper end and a lower end, wherein the upper end of the hydraulic conduit is in communication with a surface location; and inserting a stinger through the valve and into the bore receptacle, wherein the stinger is attached to the lower end of the first hydraulic conduit and wherein the bore receptacle is in fluid communication with a second hydraulic conduit in communication with a location below the valve within the wellbore; and providing the second hydraulic conduit with a valve. 28. The method of claim 27 further comprising injecting a fluid into the upper end of the first hydraulic conduit, through the bore receptacle, and through the second hydraulic conduit wherein the second hydraulic conduit communicates the fluid to the wellbore location below the valve. 29. The method of claim 27 further comprising retracting the stinger from the bore receptacle. 30. A method to communicate hydraulically with a portion of a wellbore, the method comprising: positioning and setting a bore receptacle in the wellbore, the bore receptacle being below a well valve and wherein the well valve is operable between an open position and a closed position; and deploying a hydraulic conduit into the wellbore, the hydraulic conduit including a stinger at a distal end, the stinger configured to be inserted into the bore receptacle and extracted by an extraction device when the extraction device is activated, the extraction device being located below a wellhead. 31.
