Description :
A high-quality, large 3D seismic data volume collected in a highly channelized stratigraphic series found in the upper 500 ms of the Sunda Shelf in offshore Indonesia was used to map incised valley development on this shelf. Defined on a seismic grid at 25-m spacing, 10 valley bases were then exported to ArcGIS, which was used to define each valley's thalweg. Valley-base elevation and several seismic attributes were then extracted along each thalweg. Resulting correlations and relationships could be used to infer thickness variability and reservoir characteristics of channelized deposits from 2D planform analysis and profiling.
