Method of setting and maintaining a tool in a set position for a period of time
View Patent ↗A method of setting and maintaining a tool in a set position for a period of time includes the following. Causing a component of a device to move relative to another component of the device, interengaging one or more features of at least one of the components with the another component, creating a set condition of a tool engaged with the component and the another component with the causing and interengaging. A method of dissolving at least the one or more features when removal of the tool is desired.
1. A method of setting and maintaining a tool in a set position for a period of time in a borehole, comprising:
causing a component of a device to move in a first direction relative to another component of the device during setting of the tool;
interengaging one or more features of the component with the another component during the relative movement;
creating a set condition of the tool engaged with the component and the another component with the causing and interengaging;
and during unsetting of the tool, dissolving at least the one or more features and allowing the component and the another component to move in a second direction opposite the first direction relative to each other.
2. The method of setting and maintaining a tool in a set position for a period of time of claim 1 , further comprising disengaging the component from the another component.
3. The method of setting and maintaining a tool in a set position for a period of time of claim 2 , further comprising setting a dissolution rate that results in the disengaging occurring after a selected period of time.
4. The method of setting and maintaining a tool in a set position for a period of time of claim 3 , wherein the selected period of time is after an operation has been completed.
5. The method of setting and maintaining a tool in a set position for a period of time of claim 4 , wherein the operation is one of fracing or treating a formation.
6. The method of setting and maintaining a tool in a set position for a period of time of claim 3 , wherein the setting a dissolution rate is at least in part done through selection of material of the component or the another component.
7. The method of setting and maintaining a tool in a set position for a period of time of claim 3 , wherein the setting a dissolution rate is at least in part done through selection of geometric parameters of the component or the another component.
8. The method of setting and maintaining a tool in a set position for a period of time of claim 1 , further comprising exposing at least the one or more features to a fluid configured to dissolve the at least the one or more features.
9. The method of setting and maintaining a tool in a set position for a period of time of claim 1 , further comprising exposing at least the one or more features to a fluid configured to dissolve the at least the component or the another component.
10. The method of setting and maintaining a tool in a set position for a period of time of claim 1 , wherein the movement of the component relative to the another component is longitudinal movement.
11. The method of setting and maintaining a tool in a set position for a period of time of claim 1 , further comprising longitudinally compressing the tool between the component and the another component.
12. The method of setting and maintaining a tool in a set position for a period of time of claim 1 , further comprising ratchetingly engaging the one or more features of the component with the another component.
13. The method of setting and maintaining a tool in a set position for a period of time of claim 1 , wherein the one or more features are teeth.
14. The method of setting and maintaining a tool in a set position for a period of time of claim 1 , wherein the interengaging one or more features of the component with the another component includes interengaging a third component with each of the component and the another component.
15. The method of setting and maintaining a tool in a set position for a period of time of claim 14 , wherein the component, the another component and the third component are a mandrel, a housing and a body lock ring.
16. The method of setting and maintaining a tool in a set position for a period of time of claim 1 , further comprising radially moving at least a portion of the tool with the movement of the component relative to the another component.
17. The method of setting and maintaining a tool in a set position for a period of time of claim 1 , wherein the creating a set condition includes setting slips.
18. The method of setting and maintaining a tool in a set position for a period of time of claim 1 , wherein the creating a set condition includes setting seals.
19. The method of setting and maintaining a tool in a set position for a period of time of claim 1 , wherein the tool includes a frac seat.
20. The method of setting and maintaining a tool in a set position for a period of time of claim 1 , wherein the tool is a packer.
