Traditionally basin analysis and exploration prospect studies have relied heavily on Previous HitseismicNext Hit and drilling as the main tools for structural and stratigraphic interpretation. The volume of Previous HitdataNext Hit and interpreted maps from these sources and limitations of existing contour displays creates problems in both effectively visualizing and assimilating the total picture of a basin or prospect. Two-dimensional Previous HitseismicNext Hit plan view Previous HitdisplayNext Hit techniques have lagged behind advances in Previous HitseismicNext Hit acquisition and processing and three-dimensional Previous HitseismicNext Hit Previous HitdisplayNext Hit technology.

Other datasets such as gravity, magnetics, topography, bathymetry, satellite imagery, airborne radiometrics, velocity maps and surface geological mapping containing structural information which could complement or guide the Previous HitseismicNext Hit interpretation, have been either overlooked or only partialIy integrated with Previous HitseismicNext Hit and drilling interpretations. Lack of tools to effectively integrate and interpret all geophysical and geological Previous HitdataNext Hit has been a major impediment to the use of all Previous HitdataNext Hit in basin studies.

Image processing technology has advanced to the stage where enhanced imaging of two-dimensional and three-dimensional Previous HitseismicNext Hit Previous HitdataNext Hit and integration of all relevant Previous HitdataNext Hit is now possible. All contoured or spatial (line and/or point) datasets can be gridded to a raster image and maps can be scanned or digitized to raster or vector images for input to an image processor for enhancement, combination, further processing and analysis and interpretation/annotation.

A case study from the Geological Survey of Victoria's Eastern Otway basin study, using ERMAPPER image processing software, illustrates state of the art image processing capability. Enhanced visualization and combined interpretation of two-dimensional Previous HitseismicNext Hit (time, velocity, depth), borehole (depth, thickness), gravity (land and marine), magnetics (airborne and marine), topography, bathymetry, surface geological mapping, airborne radiometrics and cultural map Previous HitdataTop has led to an improved understanding of the structural complexity of the basin.
