Abstract:
An apparatus and method to evaluate light-weight cement (LWC) bond conditions behind the casing in a downhole environment of a wellbore. The apparatus includes a logging (CBL) instrument that can detect aberrations in the LWC behind the casing based on variations in the transducer impedance measurements without using pad. The CBL instrument includes a transducer matrix, a signal acquisition controller, a data processing module, and a communication unit.
