ABSTRACT:
The properties of porous material that is hydraulically coupled to a well through openings in cased or in uncased portions of the well are evaluated. The process involves initiating a pressure wave, typically at the well head, so that the pressure oscillations extend to the porous material zone under investigation. Flow of fluid between the well and formation changes the amplitude and frequency content of the oscillations traveling up and down the well. That is, the oscillations are modulated from the form they would have in a like well with no hydraulic communication to the formation. The properties of the formation are derived from these changes.
