ABSTRACT: Beyond Outcrop Visualization: Building Reservoir and Depositional Models in a CAVE Environment

Digital mapping techniques open unprecedented possibilities for mapping surface geological features in the Previous HitfieldNext Hit. High- and low-resolution digital elevation models, orthomaps/aerial photography, very high-resolution LIDAR imaging and photorealistic models have rapidly become Previous HitdataNext Hit types that are frequently used to achieve better Previous HitdataNext Hit overview and feedback. However, these Previous HitdataNext Hit are mostly utilized for visualization purposes and not properly combined with subsurface Previous HitdataNext Hit to produce Previous HitfieldNext Hit-scale three-dimensional models of particular depositional environments. In addition, most outcrop Previous HitdataNext Hit types need to be visualized on personal computers in two dimensions, where the spatial context is severely reduced. 
Photorealistic models (cm-scale terrain models of outcrops draped with high-resolution digital photography) can be combined with behind-the-outcrop subsurface Previous HitdataNext Hit such as wells, shallow seismic and ground-penetrating radar to create a full three-dimensional depositional model. These Previous HitdataNext Hit are imported into a CAVE environment, visualized and further processed into a decimeter-scale reservoir model. The CAVE environment, where the geologist is immersed in the Previous HitdataNext Hit, is a key factor in full utilization and appreciation of the Previous HitfieldNext Hit Previous HitdataNext Hit. Obvious sources of error, such as miscalculations of angles and thicknesses, distortions and misconceptions about sedimentary geometries are automatically eliminated. The combination of different Previous HitdataNext Hit types in one environment gives direct information at cm-scale on upscaling issues, lithological calibration of seismic reflectors and enhances the understanding of depositional models. Previous HitExamplesNext Hit are provided from Carboniferous deep-water deposits in County Clare, Ireland and Ainsa, Spain. There, reservoir models are built from both a variety of depositional geometries based on photorealistic models and behind-the-outcrop Previous HitdataTop.
