Abstract In many cases we observe that log responses from ultrasonic flexural and sonic logs do not meet the expectations of the executed cementing job without showing major issues Also often the logs do not even see the cement behind the casing These scenarios are most often caused by either a wet microannulus or a dry microannulus Often the effect of a
Types of Cement Ordinary Portland Cement OPC The most widely used cement particularly for general construction reinforced concrete buildings bridges and pavements where soil conditions are normal and the concrete is not subject to sulphate hazards OPC has excellent resistance to cracking and shrinkage Slag Cements
