Image processing for seismic mapping saves papering the walls

Abstract

Correct display and interpretation of geotechnical data are critical in mineral and petroleum exploration. Subtle geophysical patterns are of particular interest in petroleum exploration where targets are becoming increasingly difficult to discern. Contour maps traditionally have been used in the petroleum industry to present data, particularly interpreted seismic horizon mapping. Improvements in computing power have enabled digital gridded and image processed data sets to be displayed quickly and easily. Subtle features within very large or complex areas can now be displayed and recognised, as exemplified by Eromanga and Otway Basin seismic horizon data sets. Enhancement of features in a particular orientation of interest to the explorationist can be accomplished by judicious choice of sun shade imagery. Integration of geological, geochemical and geophysical datasets is vital for successful petroleum exploration. Preparation of digital geotechnical databases is the key element for such efficient concentration of data. Integration of datasets into single image processed displays can then present complex information in a powerful way.
