Abstract
System and methods for engaging and disengaging running tools with a liner in a downhole system are described herein. The system and methods include a liner disposed in a borehole, the liner having at least one running tool engagement section, a running tool disposed within the liner, the running tool having at least one engagement module that is operable from a disengaged position to an engaged position and that is operable from an engaged position to a disengaged position, and an electronic device disposed at least one of in or on the engagement module.
Claims21
A system for engaging and disengaging a running tool with a liner in a downhole system comprising:
- a liner disposed in a borehole, the liner having at least one running tool engagement section including one or more liner anchor cavities;
- a running tool disposed within the liner, the running tool having at least one engagement module that is operable to move an anchor from a disengaged position to an engaged position and from an engaged position to a disengaged position;
- an electronics module disposed at least one of in or on the at least one engagement module;
- and
- a position detection system configured to detect relative positions of the liner and the running tool, the position detection system comprising:
- a marker installed within the liner;
- and
- a sensor in the running tool and configured to detect an appearance of the marker;
- the position detection system configured to communicate the appearance of the marker to the electronics module,
- wherein, once the appearance of the marker is communicated to the electronics module, the anchor is movable into engagement with one of the one or more liner anchor cavities.
A method for engaging and disengaging a running tool with a liner in a downhole system comprising:
- disposing a liner in a borehole, the liner having at least one running tool engagement section including one or more liner anchor cavities;
- disposing a running tool within the liner, the running tool having at least one engagement module that is operable to move an anchor from a disengaged position to an engaged position and from the engaged position to the disengaged position and an electronics module disposed at least one of in or on the at least one engagement module;
- detecting a relative position of the running tool relative to the liner with a position detection system, the position detection system comprising a marker installed within the liner and a sensor in the running tool configured to detect an appearance of the marker;
- communicating the appearance of the marker to the electronics module;
- and
- moving the anchor into engagement with one of the one or more liner anchor cavities of the at least one running tool engagement section, using the electronics module.
A system for engaging and disengaging a running tool with a liner in a downhole system comprising:
- a liner disposed in a borehole, the liner having at least one running tool engagement section;
- a running tool disposed within the liner, the running tool having at least one engagement module that is operable from a disengaged position to an engaged position and that is operable from an engaged position to a disengaged position, wherein the at least one engagement module comprises at least one anchor module with one or more anchors and the at least one running tool engagement section of the liner comprises at least one liner anchor cavity, the at least one liner anchor cavity configured to receive a respective anchor of the one or more anchors;
- an electronic device disposed at least one of in or on the engagement module;
- and
- a linear variable differential transformer configured to monitor the movement of the one or more anchors in the at least one anchor module,
- wherein the linear variable differential transformer comprises a fluid channel for a drilling fluid to pass the linear variable differential transformer in the running tool.
