Method for direct hydrocarbon reservoir detection and delineation by low frequency acoustic spectroscopy

1. Field of the Invention A method for detecting and identifying a type and geometric dimensions of hydrocarbon deposits and other underground fluid deposits. Sensors are used to measure anomalies caused by a deposit in a natural earth frequency spectrum. Different frequencies are filtered out and analyzed, for respective deposits. Amplitudes of maxima are separately evaluated, corresponding to separately measured frequencies. Amplitude values of the maxima are placed into correlation with each other and measuring points are determined.
