Abstract

This invention presents a different way of being able to repeatedly lock out and open a Fluid Loss Control Valve or any mechanically operated tool. The invention consists of the following items: 1. An actuating member that is able to interface with a mechanically operated tool. 2. A piston that is able to push against a housing/spring to cycle an indexing mechanism. 3. Said indexing member has a number of slots that can index a pre-determined amount/number of cycles. 4. Said indexing member has profiles/nubs that are in-line with slots that allow the invention to retain a spring force and/or loads from the piston. 5. A locking device (device could be a profile that is part of the housing/member mentioned in item 6) that locks/interfaces onto a profile after some amount of travel. 6. A housing/member that aligns the locking device to the indexing member. 7. A spring that is able to cycle the indexing member and open a mechanically operated tool.

Improvement to/Variant of Modular Hydraulic Operator for a Subterranean Tool

This invention presents a different way of being able to repeatedly lock out and open a Fluid Loss Control Valve or any mechanically operated tool.

The invention consists of the following items:

1. An actuating member that is able to interface with a mechanically operated tool.

2. A piston that is able to push against a housing/spring to cycle an indexing mechanism.

3. Said indexing member has a number of slots that can index a pre-determined amount/number of cycles.

4. Said indexing member has profiles/nubs that are in-line with slots that allow the invention to retain a spring force and/or loads from the piston.

5. A locking device (device could be a profile that is part of the housing/member mentioned in item 6) that locks/interfaces onto a profile after some amount of travel.

6. A housing/member that aligns the locking device to the indexing member.

7. A spring that is able to cycle the indexing member and open a mechanically operated tool.

The Tool operates as follows:

1. A work string is tripped out of the well; on the end of the work string is a shifting tool.

2. Said shifting tool latches onto a profile and is continued to be pulled out of hole.

3. This action compresses a spring and simultaneously moves a locking device and moves the locking device past locking nubs of the indexing member. While that happens, the member covering the indexing member is aligned in such a way that another locking device mentioned in step 6 is out of phase with its respective profile and causes no hindrance of lock...
