f 20+ YEARS OF EXPERIENCE, OBSERVATIONS, AND LESSONS LEARNED OF WITH THE MODERN DIGITAL ACOUSTIC TELEVIEWERS, AND THEIR IMPACT ON DATA QUALITY AND WITH FOCUS ON PRODUCTION MINING APPLICATIONS. PART I – BASIC THEORY, APPLICATIONS, PROCESSING STEPS, RESOLUTIO

The modern slimhole digital acoustic televiewer has been applied for the last 20+ years for a variety of applications from ground water to rock mass evaluation to casing inspection. After an extended period of limit application, the technology is now widely accepted and hundreds of tools are in the market place and routinely being applied by service and in-house groups around the world. During this time, a number of lessons have been learned and observations noted. Understanding and learning from these observations and details are critical in insuring highest quality and correct application of the data. Despite the great advances in instrumentation, lack of training with resulting mistakes in acquisition, common misconceptions and errors in the processing and interpretation of the data lead generate bad data that is frequently not identified.
