Abstract
Hydrocarbon Microtremor Analysis (HyMAS) is an innovative technology for identifying the presence of hydrocarbon containing geological structures by analyzing low frequency background wave signals. A possible interpretation of this reproducibly observable phenomenon is the excitation of hydrocarbon related resonances. Synthetic spectra produced by basic linear and non-linear one-dimensional models of an oscillating liquid filled porous medium show characteristic features of measured HyMAS spectra when oceanic background waves around 0.1-0.2 Hz are assumed to be the external driving force.
