Attributes from surface-based spectroscopic studies of the ambient wave field are hypothesized to be at least partly controlled by subsurface hydrocarbon accumulations. Such attributes can a useful de-risking tool for exploration and development, but they generally also sensitive anthropogenic activity other physical near-surface variables. This work introduces statistical strategy correlate as function frequency both targets well potential surface confounders reduce misinterpretations. A resulting unconfounded correlation its uncertainty then used quantitative risk assessments. The is illustrated on passive seismic data set acquired over Jonah in Wyoming, USA. power correlates best pore thickness 1.0-3.5 Hz. Anthropogenic activity, inferred high energy, elevation found uncorrelated do not require compensation. More such geology or trap structure should tested using this methodology.
