Abstract: A device and method used to inspect wellbores, cased or uncased using cameras and a phased array ultrasound transducer. The optical and ultrasound images are stored on the device and then registered and analyzed together. The present device overcomes the deficiencies currently experience by downhole camera operators, such as poor scale and lack of volumetric perspective.

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.

Abstract: A device and method used for inspecting and measuring coiled tubing, production tubing or drill pipe as it enters the well. Defects such as internal and external wall loss, cracking and deformation can be detected and quantified. The axial motion of the tubing can be measured allowing for depth measurements that are more accurate and reliable than what can be obtained using an encoder wheel system.

Abstract: A device and method used to inspect wellbores, cased or uncased using cameras. Improvements in downhole optical imaging are provided using telecentric lens, prisms and mirrors, or structured lighting. Stereoscopic arrangements and ultrasound sensor may provide 3D or contour information. The images are stored on the tool and analyzed later. The present tool overcomes the deficiencies currently experience by downhole camera operators, such as poor scale and perspective.

Abstract: A device and method for manipulating a robotic end effector in a well. Actuators manipulate the end effector independently through multiple degrees of freedom to improve the perspective of the end effector. An imaging sensor may be used to image, measure and identify features of a well and objects located therein. The sensor may be an ultrasound transducer, camera or x-ray sensor arranged radially, axial or distributed over a 2D surface. The end effector may be connected to a tool, such as a fishing tool, a welder, a milling tool, or a repair tool.
