Crain's Petrophysical Handbook - Cement Integrity Logs - Part 2 .Cement Mapping Tools (CET, PET, CMT) Cement evaluation (CET) and cement mapping (CMT) tools continue to use many of the features of cement bond (CBL) logs, but add a new feature - a circumferential image representing the cement quality, or lack of it. The ultrasonic imaging (USI) tool, an offshoot of the openhole.cement evaluation logging handbook at,Cement bond logs - - PetroWikiJun 25, 2015 . Just as filtrate invasion and formation alteration may produce changes in formation acoustic properties, and thus variation in acoustic logs over time, so too, cement-bond logs may vary over time as the cement cures and its properties change. Modern acoustic cement-evaluation (bond) devices are.Microannulus and Cement Evaluation: Effectiveness of Cement .Cement evaluation with wireline tools is one of the primary means for determining whether the objectives of a cementing job have been reached once the job is finished. Several logging techniques are currently available for measuring cement quality, including sonic cement bond logs (CBL) and ultrasonic logs. These logs.
