Abstract: A method, imaging tool and computer system for locating external devices mounted to a tubular in a wellbore. The identification of devices, such as cable clamps, enables other tools in the string to operate more precisely. A computer model is used to locate the devices from acoustic images, which images are acquired using a downhole imaging tool having an acoustic sensor or acoustic array. The model may be a classifier, which may be machine trained to classify whether a device is present, its location and its orientation. Automating this locating enables very long wellbores to be processed quickly.

Abstract: A method, apparatus and system for locating external apparatus mounted to a tubular in a wellbore. The identification of apparatus, such as cable clamps, enables other tools in the string to operate more precisely. A computer model is used to locate the apparatus from acoustic images, which images are acquired using a downhole device having an acoustic sensor or acoustic array. The model may be a classifier, which may be machine trained to classify whether an apparatus is present, its location and its orientation. Automating this locating enables very long wellbores to be processed quickly.

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 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.
