Investigation Of Hydrocarbon Microtremors Using Low Frequency Passive Seismic Method In A Gas Field, Thrace Basin, Turkey

Low Frequency-Passive Seismic Method (LF-PSM) is a new technique that uses low frequency noise to determine the reservoir’s existence in oil and gas fields. As an indicator of the hydrocarbons, such method can be used to find the existence of the reservoir. In this method, spectral characteristics of the noise induced by reservoir are investigated where the first attribute quantifies the spectral energy in the vertical wavefield component and the second attribute quantifies the maxima in the vertical-to-horizontal spectral ratios. An increase in the spectral energy, so-called hydrocarbon microtremor, generally exists in the frequencies between ∼1 and ∼3 Hz. In addition to the conventional exploration methods, it can be applied as a complementary approach.
