Abstract
A method of determining a presence of hydrocarbons is disclosed. The method includes obtaining a surface seismic dataset, composed of a plurality of seismic gathers, determining a redatumed gather for a target horizon based on the seismic gather, determining a time window of the redatumed gather around the target horizon, and determining a spectrum of a portion within the time window. The method further includes determining a hydrocarbon indicator based, at least in part, on an amplitude of a higher-frequency portion and lower-frequency portion of the spectrum of the plurality of seismic gathers, determining a geographic map of values of the hydrocarbon indicator from the plurality of seismic gathers, and determining a presence of hydrocarbons based, at least in part, on at least one anomalous value on the geographic map. A system including a seismic acquisition system and a seismic processor for executing the method is disclosed.
