Abstract: A wireline shifting tool comprising an anchor, a linear actuator, and a shifter may be at least partially controlled by one or more measurements indicating an amount of force applied to the anchor, the linear actuator, the shifter, or a combination thereof. For example, a processor may receive the one or more measurements and perform a seeking operation or cause a graphical user interface (GUI) to display information that may inform a user regarding operations associated with the wireline shifting tool.

Abstract: A method includes disposing an intervention service tool within a tubular. The intervention service tool includes an anchoring system, a shifting system, and a linear actuator system. The tubular includes a shifting profile geometry disposed within the tubular at a first location. The anchoring system, the shifting system, and/or the linear actuator system is actuated. Shifter system pressure, linear actuator system force/pressure, and displacement of the shifting system is measured. A known graph of the shifting profile geometry is compared to one or more of a measured pressure, a measured force, or a measured displacement. A position of a key disposed on the shifting system is determined relative to the shifting profile. The shifting profile geometry is engaged with the key based on the position of the key. The shifting profile geometry is positioned at a second location that is different from the first location.

Abstract: In conventional wireline intervention shifting service, the success of the operation is heavily dependent on the engineer’s experience and knowledge. Any wrong judgement in the process of operation could lead to non-productive time or even total failure. Once the operation is completed, the post-job processing and report preparation also require significant manual effort and are extremely time consuming, which often leads to the inadequate or incomplete report. These challenges are addressed by the advanced surface acquisition software presented in this paper. The aim of the surface software is to redefine the selective shifting workflow by leveraging the available instrumentation, streamlining and simplifying operation procedures, eliminating or reducing the typical human errors observed earlier, and greatly reducing the burden on the field engineers for post-job deliverables with automated real-time data collection, processing, and report generation.

Abstract: Apparatus and methods for autonomously shifting a downhole sliding sleeve. A shift tool includes a shifter arm, an artificial neural network, and a control circuit. The artificial neural network is trained to identify engagement of the shifter arm with a shifting feature of a sliding sleeve. The control circuit is configured to extend the shifter arm at a first pressure for seeking engagement with the shifting feature of the sliding sleeve, and responsive to the artificial neural network recognizing engagement of the shifter arm with the shifting feature of the sliding sleeve, extend the shifter arm at a second pressure for shifting the sliding sleeve.

Abstract: A service tool that may be inserted into a tubular, the service tool includes an anchoring system. The anchoring system includes a body having a first end, a second end, and an opening extending along a portion of the body between the first end and the second end and a gripping assembly housed within and coupled to the body. The gripping assembly may anchor at least a portion of the service tool to the tubular, and the gripping assembly includes a plurality of anchor arms disposed within the opening and that may move relative to the body. The anchoring system also includes an actuator disposed within a central bore of the body and coupled to the gripping assembly.
