The UCI* Ultrasonic Corrosion Imager is an evolution of the USI Ultrasonic Imager. The UCI tool provides all the answers required to locate, identify, and quantify casing damage or corrosion. The design is specifically engineered for High-azimuthal-resolution images and detailed examination of both the inner and outer surfaces of casing ranging from 41⁄2 to 133⁄8 in. [11.43 to 33.97 cm]. Combination USIT with CBL-VDL tools is the advantage to have result in one run to save the rig time .
