Earth Modeling: Bridging Functionality Gaps Using gOcad

John Schaefer and Tom Wondolleck. ( 1998 )
in: 18th gOcad Meeting, ASGA

Abstract

gOcad is being used inside of Landmark Graphics to address both near-term and longterm issues. Examples of near-term use involve gOcad being used to bridge workflow functionality gaps that exist with our current applications. Two such uses will be illustrated in this paper. The more important, and longer term use of gOcad involves its application as a prototyping tool for new functionality that may be exposed in future software offerings, as gOcad functions and associated data types mature. The first workflow shows an application of gOcad’s Cluster Analysis to delineate the extent of a seismically thin fluvial reservoir. These lower Cretaceous age sands were deposited in shallow inresulted in occasional dry holes. Applying cluster analysis to a voxet cised valleys in southern Alberta. A drilling program based on seismic amplitudes containing 3D seismic amplitudes has successfully distinguished between productive and non-productive wells, and suggest the possibility of a significant field extension. The second workflow illustrates the use of gOcad to construct a 3D structural model from the Bolivian fold belt using 13 cross-sections as a starting point. The model was then used to create a velocity model that was used for ray tracing and depth migration.
