We present a seismic reprocessing and seismic reservoir characterisation case study for a legacy onshore dataset acquired in the Bowen Basin, Australia, in 2003. The study demonstrates the benefits of using contemporary signal processing and imaging technologies to maximize the value in legacy seismic acquisition datasets. These modern techniques address the complex geophysical challenges posed by coal reflectivity responses including noise and multiple generation. The study achieved the sub-surface geological objectives to accurately estimate the rock properties for use in seismic reservoir characterization lithology mapping, specifically to distinguish between sand and coal lithologies.
