Seismic imaging of thrust faults and structural damage: a visualization workflow for deepwater thrust belts

摘要

Combinations of increasingly sophisticated software and hardware have greatly improved the imaging of geologic structure and stratigraphic features in seismic datasets (Marfurt and Chopra, 2007). Today the seismic interpreter can quickly create attribute maps, using specific filtering workflows to identify, visualize, and isolate faults and fracture systems at different scales. Such techniques have been successfully applied for imaging normal faults (Dutzer et al., 2009) within reservoirs associated with extensional sedimentary basins (Chopra and Marfurt, 2007). However, most of the adopted interpretation strategies assume fault structures to be rather simple – represented as narrow curvi-planar surfaces that transect the seismic data.
