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.
