Method for analysis seismic data with attribute functions
Abstract:
A method for stratigraphic analysis of seismic data comprises: selecting a seismic data volume comprising a plurality of samples; selecting a number of horizons within the seismic data volume; selecting a scale of interest within the seismic data volume, which ranges from 500 m up to the size of the entire seismic data volume; applying an attribute function to at least one of the selected number of horizons at the selected scale of interest; and displaying a stratigraphic attribute, which represents a geologic feature, such as a seismic facies attribute, an unconformity attribute and/or a thinning attribute that highlights a rate of thickness change of a formation layer between adjacent horizons, as a result of applying the attribute function at the selected scale of interest. These attributes facilitate understanding of moderate to large-scale seismic geometries (500 m to 50 Km) and basin development over geologic time.
