Abstract

Embodiments of the present disclosure include a method of replacing valve operation methods during fracturing operations including installing a first operator on a first valve of a first fracturing tree. The method also includes installing a second operator on a second valve of a second fracturing tree, the second fracturing tree being adjacent the first fracturing tree. The method also includes removing the first operator from the first valve, the first valve maintaining a position on the first fracturing tree after the first operator is removed. The method further includes removing the second operator from the second valve, the second valve maintaining a position on the second fracturing tree after the second operator is removed. The method also includes installing the first operator on the second valve after the first operator is removed from the first valve and after the second operator is removed from the second valve.

First claim

The invention claimed is:

1. A method for conducting hydraulic fracturing operations, the method comprising:
positioning a plurality of fracturing trees at a well site, the well site associated with the hydraulic fracturing operations;
including a first valve on a first fracturing tree of the plurality of fracturing trees, the first valve being coupled to an actuator to control operation of the first valve and the actuator being operated remotely by an operator that is not within a predetermined proximity of the first fracturing tree;
performing the hydraulic fracturing operations through the first tree;
removing the actuator from the first valve after the hydraulic fracturing operations through the first tree are complete;
installing the actuator on a second valve on a second fracturing tree of the plurality of trees; and
performing the hydraulic fracturing operations through the second tree.

2. The method of claim 1 , further comprising:
installing a manual operator on the first valve after the actuator is removed.

3. The method of claim 2 , wherein the manual operator comprises a hand wheel.

4. The method of claim 2 , wherein the first valve includes a quick connection bonnet enabling removal of the actuator without removing a valve stem of the first valve.

5. The method of claim 2 , wherein the first valve comprises a rotary to linear converter, the rotary to linear converter transforming rotational movement of the manual operator into linear movement for driving a valve stem of the first valve.

6. The method of claim 1 , further comprising:
removing the actuator from the second valve after the hydraulic fracturing operations through the second tree are complete; and
installing the actuator on a third valve on a third fracturing tree of the plurality of trees.

7. The method of claim 1 , wherein the actuator comprise a hydraulic actuator, a pneumatic actuator, an electric actuator, or a combination thereof.

8. The method of claim 1 , further comprising:
positioning a secondary system for operating the actuator at the well site;
coupling the secondary system to the actuator on the first valve;
decoupling the secondary system from the actuator before the actuator is removed from the first valve; and
coupling the secondary system to the actuator on the second valve after the actuator is installed on the second valve.

9. The method of claim 1 , wherein the plurality of fracturing trees are arranged within a predetermined proximity of one another, the predetermined proximity being within a distance such that personnel cannot operate adjacent fracturing trees of the plurality of fracturing trees during the hydraulic fracturing operations through one of the fracturing trees of the plurality of fracturing trees due to regulations or procedures.

10. A method of replacing valve operation methods, the method comprising:
installing a first operator on a first valve of a first fracturing tree, the first operator being an actuator that controls operation of the first valve;
installing a second operator on a second valve of a second fracturing tree, the second fracturing tree being adjacent the first fracturing tree, and the second operator being a manual operator that is controlled by physical control with the manual operator;
performing a first hydraulic fracturing operation using the first fracturing tree;
completing the first hydraulic fracturing operation using the first fracturing tree;
removing the first operator from the first valve, the first valve maintaining a position on the first fracturing tree after the first operator is removed;
removing the second operator from the second valve, the second valve maintaining a position on the second fracturing tree after the second operator is removed; and
installing the first operator on the second valve after the first operator is removed from the first valve and after the second operator is removed from the second valve.

11. The method of claim 10 , further comprising:
installing the second operator on the first valve after the first operator is removed from the first valve.

12. The method of claim 10 , further comprising:
performing a second hydraulic fracturing operation using the second fracturing tree;
completing a second hydraulic fracturing operation using the second fracturing tree;
removing the first operator from the second valve, the second valve maintaining a position on the second fracturing tree after the first operator is removed.

13. The method of claim 10 , wherein the first valve comprises a rotary to linear converter, the rotary to linear converter transforming rotational movement of the first operator into linear movement for driving a valve stem of the first valve.

14. The method of claim 10 , where the first and second valves include respective quick connection bonnets enabling removal of the first and second operators without removing respective valve stems of the first and second valves.

15. The method of claim 10 , wherein the first operator comprises a hydraulic operator, a pneumatic operator, an electric operator, or a combination thereof.

16. A method for performing hydraulic fracturing operations, the method comprising:
positioning a first fracturing tree at a well site, the first fracturing tree including a first valve controlling a first flow through the first fracturing tree;
positioning a second fracturing tree at the well site, the second fracturing tree including a second valve controlling a second flow through the second fracturing tree, the second fracturing tree being positioned adjacent the first fracturing tree such that access to the second fracturing tree is restricted while the first fracturing tree is in use;
performing the hydraulic fracturing operations through the first fracturing tree;
removing a first operator from the first valve, the first valve maintaining a position on the first fracturing tree after the first operator is removed, and the first operator being an actuator;
removing a second operator from the second valve, the second valve maintaining a position on the second fracturing tree after the second operator is removed, and the second operator being a manual operator;
installing the first operator on the second valve after the first operator is removed from the first valve and after the second operator is removed from the second valve; and
performing the hydraulic fracturing operations through the second fracturing tree.

17. The method of claim 16 , wherein the first operator comprises a hydraulic operator, a pneumatic operator, an electric operator, or a combination thereof.

18. The method of claim 16 , where the first and second valves include respective quick connection bonnets enabling removal of the first and second operators without removing respective valve stems of the first and second valves.

19. The method of claim 16 , further comprising:
removing the first operator from the second valve; and
installing the first operator on the third valve on a third fracturing tree, the third fracturing tree being adjacent the first and second hydraulic fracturing trees.

20. The method of claim 16 , wherein the manual operator comprises a hand wheel.
