In evaluating cementation practices, there are 2 (two) methods that are frequently used, namely are sonic wave method and ultrasonic wave method. Supervise the work of data management project staff. USIT is ultrasonic imaging tool, which covers 360deg. Individual acoustic reflections from the inner and outer pipe wall give a pipe thickness log, helpful in locating corrosion, perforations, and casing leaks. Historical Aspect -Schlumberger brothers, Conrad and Marcel, are credited with inventing electrical well-logs. Cement Bond Logs (CBL) and/or Cement Evaluation Lo gs are usually run to evaluate . The log is typically obtained from one of a variety of sonic -type tools. As a formation evaluation tool, its application is limited to conductive muds.

It may be run in several configurations and provides up to five resistivity measurements. Therefore, in this paper the effects of the important parameters on cement bond logs including casing size, well deviation, type of fluid, and mud weight during the logging operations, surface applied pressure and microannulus, fast formations, type of formation, tool eccentricity, casing eccentricity, multiple casings, pressure and temperature . To remember about USIT USIT-CBL together: gives an answer for most of the cases The casing condition will affect the log The cement quality is evaluated real time. Water velocities can be computed from the station measurements with sensitivity down to ~2-4 ft/min. Evaluating cement bond. The most important is to read log correctly, as such wrong interpretation of the raw data can lead to costly consequences. It is an ultrasonique tool , it can provide an indication of the material behind the casing (solid , liquid or gas) as an oriented VDL. The annulus is thin or the process window is long.
