Seismic modelling of coal bed methane strata, Willow Creek, Alberta

Sarah E. Richardson, Rudi Meyer, Don C. Lawton, Willem Langenberg


A numerical seismic modelling study of a coal zone in Upper Cretaceous sediments in central Alberta shows that seismic data with a dominant frequency of 100 Hz is required to map the coal zone and to resolve the lateral faces variations within. Shale plugs may be distinguished at these frequencies, but seismic data with a central frequency greater than 150 Hz would be necessary to resolve individual coal seams.
