Abstract
A downhole imaging tool and method of operating the tool in a wellbore. An imaging sensor array at an end of the tool is rotatable about a longitudinal axis of the tool to image the well by sweeping out a 2D area of the well. Actuators in the tool provide rotation and/or extension of the sensor array to change perspective. An ultrasound phased-array may be used to measure and identify features of the well or objects.
Claims21
A downhole device comprising:
- an elongate housing deployable in a well, the housing containing at least two actuators;
- and
- an end effector located at a distal end of the housing and transversely movable thereto,
- wherein the at least two actuators are coupled to the end effector to move the end effector substantially in a transverse plane with respect to the elongate housing, while maintaining the end effector's orientation during transverse movement.

A method of operating a downhole device having a robotic end effector coupled to a sensor or end effector, the method comprising:
- using a wireline, deploying the device in a well;
- operating actuators within a housing of the device to move the end effector in transverse directions with respect to the well;
- and
- operating the tool or sensor on a wall of the well or object within the well during the transverse movements.
