摘要：
The integrity of a well is evaluated using a non-invasive and lower cost screening system and method. The system and method identify whether well integrity has degraded and whether there is a clear break in the casing of a well, a corroded patch or faults in the casing. This is accomplished without requiring entry into the well.
