A chain wear system for monitoring an amount of wear of a chain operating on a plurality of sprockets may include a chain monitoring device configured for determining a length of the chain passing by a point in an amount of time, a sprocket monitoring device configured for determining the amount of sprocket rotation of at least one of the plurality of sprockets in the amount of time, and a processing system in signal communication with the chain monitoring device and the sprocket monitoring device. The processing system may be configured for calculating the amount of wear based on the length of the chain and the amount of sprocket rotation.

Chain wear sensor

A coiled tubing injector system includes a traction system for advancing coiled tubing through the injector and into or out of a well. The traction system includes a plurality of carriers () and gripper shoes () configured to repeatedly propagate through the injector along guides (). The traction system also includes a position monitor () for monitoring the lateral position of the carrier, gripper shoe, or portion thereof as the carrier and gripper shoe propagates along the coiled tubing path.

Coiled tubing injector with gripper shoe carrier position monitor

The present disclosure relates to novel and advantageous devices, systems, and methods for stabilizing a coiled tubing guide extending from a coiled tubing unit. Stabilization of the guide may mitigate movement of the guide from lateral operational forces. The guide may be stabilized by clamping or anchoring a connection point between the guide and the unit, such as between the guide and a coiled tubing injector frame or a tubing guide mount coupled to the coiled tubing injector frame. In general, a clamp or other mechanism may operate to preload the pinned connection with a prescribed force. The direction of the force may be perpendicular, or near perpendicular, to an axis of rotation about which lateral loading on the guide causes moment forces.

Tubing guide stabilization

A guide assembly for a downhole tool and related method is disclosed. The guide assembly comprises a guide housing, flappers, and a driver. The guide housing has a passage to receive the downhole tool therethrough. The flappers are movably positionable about the passage to selectively reduce an inlet thereto. The driver comprises a translator rotationally coupled to the flappers via the rods and an actuator to rotate the translator. The flappers are rotatable between the closed and the open position by the driver whereby passage of the downhole tool into the passage is selectively permitted. The translator may be a cam, gear, or rotary driver. The actuator may axially or rotationally drive the translator.
