Abstract

A liner hanger and packer are set at different times in a single trip without intervention. The running tool has a ball seat that accepts a ball for pressuring up which results in movement of a mandrel with a magnet mounted to it past a valve triggered by the magnetic field. Potential energy is released to set the liner hanger. Further mandrel movement then releases the running tool once the liner is supported by the hanger. After a cement job that starts with confirmation of release of the running tool, the same magnet is moved past another valve adjacent the liner top packer. Another valve is triggered open to release potential energy and move parts that set the packer. The running tool is removed from the liner and brought to the surface.

First claim

We claim:

1. A method of operating multiple tools with actuators therefor at a subterranean location, comprising:
running in, to a predetermined subterranean location, a tubular string on a running tool, said running tool connected adjacent a lower end of a running string;
mounting the multiple tools and actuators therefor exterior to said tubular string for said running in;
mounting a triggering device on said running tool for said running in,
sequentially setting said multiple tools with said triggering device with movement of said running tool relative to the tubular string, a first of said tools being set while said tubular string is supported by said running tool;
releasing from said tubular string and removing said running tool and running string from the subterranean location.

2. The method of claim 1 , comprising:
moving said triggering device with respect to said tubular string to actuate the first of said tools.

3. The method of claim 2 , comprising:
mounting said triggering device on a telescoping component of said running tool.

4. The method of claim 3 , comprising:
moving said triggering device longitudinally with applied pressure to said telescoping component.

5. The method of claim 1 , comprising:
releasing from said tubular string and removing said running tool and running string from the subterranean location;
moving said running tool with said running string after setting the first of said tools and after said releasing from said tubular string to set a second of said tools.

6. The method of claim 5 , comprising:
setting said first and second tools with discrete longitudinal movements of said triggering device.

7. The method of claim 6 , comprising:
mounting said triggering device on a telescoping component of said running tool.

8. The method of claim 7 , comprising:
moving said telescoping component relative to said tubular string to set the first of said tools with internal pressure in said running tool.

9. The method of claim 8 , comprising:
making said first of said tools a hanger for said tubular string.

10. The method of claim 9 , comprising:
making a second of said tools a packer for said tubular string.

11. The method of claim 10 , comprising:
using a magnet as said triggering device.

12. The method of claim 1 , comprising:
employing a magnet as said triggering device.

13. The method of claim 1 , comprising:
employing hydrostatic pressure available at the subterranean location to selectively drive discrete pistons that comprise said actuators to set the first and a second of said multiple tools.

14. A method of operating multiple tools with actuators therefor at a subterranean location, comprising:
running in, to a predetermined subterranean location, a tubular string on a running tool, said running tool connected adjacent a lower end of a running string;
mounting the multiple tools and actuators therefor exterior to said tubular string for said running in;
mounting a triggering device on said running tool for said running in;
sequentially setting said multiple tools with said triggering device with movement, of said running tool relative to the tubular string triggering at least one of said multiple tools to set;
moving said triggering device with respect to said tubular string to actuate a first of said tools;
continuing to support said tubular string with said running tool when actuating said first of said tools;
releasing from said tubular string and removing said running tool and running string from the subterranean location;
mounting said triggering device on a telescoping component of said running tool;
moving said triggering device longitudinally with applied pressure to said telescoping component;
landing an object on a seat to allow pressure buildup to move said telescoping component.

15. The method of claim 14 , comprising:
selectively blocking a passage in said running tool;
building pressure in said running tool to release said running tool from said tubular string when said tubular string is supported due to setting of said first tool.

16. The method of claim 15 , comprising:
dropping a second object on a second seat in said running tool for said selectively blocking;

blowing out said object and said second object into a catcher at a lower end of said tubular string.

17. A method of operating multiple tools with actuators therefor at a subterranean location, comprising:
running in, to a predetermined subterranean location, a tubular string on a running tool, said running tool connected adjacent a lower end of a running string;
mounting the multiple tools and actuators therefor exterior to said tubular string for said running in;
mounting a triggering device on said running tool for said running in;
sequentially setting said multiple tools with said triggering device with movement of said running tool relative to the tubular string triggering at least one of said multiple tools to set;
releasing from said tubular string and removing said running tool and running string from the subterranean location;
employing hydrostatic pressure available at the subterranean location to selectively drive discrete pistons that comprise said actuators to set a first and second of said multiple tools;
employing said triggering device to open a valve such that hydrostatic pressure is allowed to act on said pistons against an opposing lower pressure force to drive said pistons sequentially in setting said first and second tools.

18. The method of claim 17 , comprising:
providing a hanger and a packer as said first and second tools.

19. A method of operating multiple tools with actuators therefor at a subterranean location, comprising:
running in, to a predetermined subterranean location, a tubular string on a running tool, said running tool connected adjacent a lower end of a running string;
mounting the multiple tools and actuators therefor exterior to said tubular string for said running in;
mounting a triggering device on said running tool for said running in;
sequentially setting said multiple tools with said triggering device with movement of said running tool relative to the tubular string triggering at least one of said multiple tools to set;
releasing from said tubular string and removing said running tool and running string from the subterranean location;
communicating a setting signal for setting said multiple tools through a wall of said tubular string that lacks penetrations.
