Abstract

Evidence is given for the identification of subsurface structure in west Texas using satellite imagery. A system of digital data integration is proposed for the confirmation of image interpretation. A strategy for using these techniques to aid in the exploration for hydrocarbons is developed.

Map data and image data may be digitally integrated to provide improved confidence in interpretations made from either source. Surface features identified from drainage/topographic patterns may relate to subsurface structure. Surface linear features may be related to subsurface faulting. These surface features can be of assistance in the interpretation of both well data and seismic data. Gravity and aeromagnetic data can be integrated into the data package to further refine the surface and subsurface interpretation once the overall characteristics and limitations of these data sources are understood. Existing seismic data must be evaluated not only on the basis of vintage and visual quality, but also on its location relative to drainage and interpreted features. Other data such as well information and land or lease holdings can be added along with geological, facies, clastic ratio, carbonate percentage, porosity, permeability or any other maps which would be appropriate to the area of study. Use of a digitally integrated data package will improve the efficiency of an exploration program by making sure that expensive exploration databases are fully utilized in the identification and ranking of exploration targets.
