Abstract
A novel method is disclosed for using the resonance behavior of reservoir sand to distinguish between oil-rich, gas-rich and water-rich zones. A wellbore is logged, as for example with a long spaced acoustic logging tool, to obtain data which are then interpreted to determine the damping of the acoustic signal in one sand versus another, or in that sand versus a reference sand having similar resonance characteristics.
