Description

The use of acoustic tools in the evaluation of cement placement is an established practice.  The measurement concept relies on an acoustic wave being transmitted along the casing and received back at the tool.

The magnitude of energy loss is used to establish an acoustic coupling between casing and cement and, based on the degree of energy loss, infer the presence of cement and hydraulic isolation.
