Claims
- 1. A method of moving a through-the-flowline installed safety valve having a tubular operator through a curved flow line loop of a well head assembly including the steps of:
- controlling the fluid pressure in the curved flow line loop for moving the safety valve through the curved flow line loop; and
- flexing the tubular operator of the safety valve to enable passage of the safety valve through the curved flow line loop.
- 2. The method as set forth in claim 1, wherein the step of flexing includes:
- flexing the controllable safety valve at a plurality of locations to enable passage through the curved flowline loop.
- 3. The method as set forth in claim 1, including the step of:
- connecting the controllable safety valve with a carrier tool means prior to the step of controlling the fluid pressure in the curved flow line loop for moving the controllable safety valve.
- 4. A method of moving a through-the-flowline installed safety valve having a tubular operator through a curved flowline loop of a well head assembly including the steps of:
- moving the safety valve through the curved flowline loop; and
- flexing the tubular operator of the safety valve to enable passage of the safety valve through the curved flowline loop.
- 5. The method as set forth in claim 4, wherein the step of flexing includes:
- flexing the controllable safety valve at a plurality of locations to enable passage through the curved flowline loop.
- 6. A method of moving a through-the-flowline installed safety valve through a well tubing having a bend providing a restriction to passage by the controllable safety valve through the bore of the well tubing, said safety valve having a tubular operator for effecting operation of said valve including the steps of:
- moving the safety valve through the bore of the well tubing; and
- flexing the tubular operator of the safety valve adjacent the bend to enable passage of the safety valve past the movement restriction provided by the bend.
- 7. The method as set forth in claim 6, wherein the step of flexing further includes:
- flexing the controllable safety valve at a plurality of locations to enable passage past the restriction provided by the bend.
- 8. The method as set forth in claim 6, including the step of:
- controlling the fluid pressure in the bore of the well tubing for moving the controllable safety valve through the bore of the well tubing.
- 9. The method as set forth in claim 6, including the step of:
- connecting a carrier tool means with the controllable safety valve prior to the step of moving the controllable safety valve through the bore of the well tubing.
