Enhancements in acquisition and processing software allow many people to collect acoustic televiewer data with minimal training. However, these tools are extremely sophisticated and flexible and it is easy to generate data with significant error. These errors can occur in data acquisition from misunderstanding image orientation scheme and requirements; use of magnetic centralizers or housing; use in a magnetic environment; from in correct tool sample decisions and logging too fast. They can also occur from tool orientation sensor or software failure. The most common issues with data quality are tool centralization and borehole fluid conditions and incorrect presentation scales. Accessory logs accompanying the image data can frequently be used to identify these data issues.
