Abstract: Methods, computing systems, and machine-readable media for detecting downhole sand entry points are provided. A computing device receives a sand detection output of a product sand detection tool and a raw timeseries waveform corresponding to an input to the product sand detection tool. Based on the sand detection output, at least one downhole sand entry point is detected at a logging depth. In response to the detecting of the at least one downhole sand entry point. the computing device extracts a subset of features based on the raw timeseries waveform. The computing device determines whether the detecting is a true positive or a false positive based on the extracted subset of the features and a trained Random Forest classifier. A remedial action is performed regarding the at least one downhole sand entry point responsive to the determining that the detecting is the true positive.

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: This device comprises a cable working line bearing a lower assembly and a winch for maneuvering the line. The hydraulic central unit (46) of the winch includes a tank (50) for storing a hydraulic control fluid, a pump (52) for driving the hydraulic fluid, connected to the tank (50) through an upstream conduit (54) and at least one hydraulic motor (56) for driving the drum (42) connected to the pump (52) through an intermediate conduit and connected to the tank (50) through a downstream conduit. The hydraulic central unit comprises a regulator (62) for the hydraulic fluid flow rate at the outlet of the pump (52). The regulator (62) is driven according to at least one hydraulic fluid pressure depending on the load exerted on the motor (56) by the rotary drum (42), said or each pressure being directly taken on one of said conduits.

Abstract: This tool comprises an upper portion and a lower portion able to move relative to each other between a connected position and a completely disconnected position. The tool comprises an immobilization member that can be freed from the upper portion relative to the lower portion, a member for releasing the immobilization member, and a mechanism for moving the release member housed in the tool. The movement mechanism comprises an actuator and a receptor for receiving a control signal.

The tool comprises an immobilization member that can be freed from the upper portion relative to the lower portion, a member for releasing the immobilization member, and a mechanism for moving the release member housed in the tool. The movement mechanism comprises an actuator and for a receptor receiving a control signal. The movement means comprises a member for elastic stressing of the release member towards its release position and a retaining member for keeping the release member in an activation position against the stressing member. The actuator is able to release the retaining member after receiving the control signal.
