Abstract
We are describing a pilot study investigating the use of sonification techniques in seismic interpretation for oil exploration. Due to emerging development criteria of conformance and usefulness, the project was redirected from a free experimental tool box to a primitive but functioning work station for seismic interpretation. The emphasis was put on extracting interesting seismic parameters for sonification. The most important elements are objects (allowing encapsulation of structures), attributes (allowing multiple data sets for each object) and methods (how the chosen data is transformed to sound). Among the methods are standard mapping from data value to pitch, mapping from structural position to pitch, mapping from entire object content to sound with moving objects. All methods can be both mouse-driven and automatic. The audio is MIDI-based using common soundcards. Separation of different data streams are done by instrumentation, octave placement and panning. The major assets of using sound were evaluated to be multidimensionality, time resolution, pattern sensibility and new data representations (methods). The pilot study ended successfully insofar that it will be integrated in a new software package featuring 3D-visualization and audio for seismic interpretation.
