“Cable” and other extraneous energy in well velocity surveys may be identified and distinguished from “formation” energy by using phase relationships. Conventional instruments with at least two different narrow band‐pass filters provide sufficient data to achieve good results even in the presence of extreme amounts of interference. The method is illustrated by laboratory tests and an actual well survey.
