Seismic imaging and voelocity analysis for an Alberta Foothills seismic survey

摘要

Seismic imaging of complex structures form the west- ern Canadian Foothills can be achieved by applying the closely coupled processes of velocity analysis and depth migration. For the purposes of defining these structures in the Shaw Basing area of western Albertta, we per- formed a series of tests on both synthetic and real data to find optimum imaging procedures for handling large topographic relief, near-surface velocity variations, and the complex structural geology of steeply dipping for- mations.
