Abstract: A method is described for determining well integrity including deploying seismic sensors in a wellbore; attaching a vibrational source to well hardware; using the vibrational source to generate seismic signal that moves through the wellbore; creating a seismic dataset by recording the seismic signal at the seismic sensors; and processing the seismic dataset to make a processed seismic image. The processed seismic image may be displayed on a graphical display in order to identify well integrity problems such as wellbore deformation, well casing damage, or problems with cement.
