Analyzing seismic imagery in the time-amplitude and time-frequency domains to determine fluid nature and migration pathways: A case study from the Queen Charlotte Basin, offshore British Columbia

►Time-amplitude and time-frequency analysis of multi-resolution seismic data. ►Original technique to enhanced anomalous amplitudes on seismic sections. ►Time-frequency analyses show that anomalous amplitude contrasts are caused by gas. ►Improved understanding of fluid flow in the Queen Charlotte Basin.
