f Virtual Outcrop Models: Case Study from the Paleozoic Sandstone Reservoir and Aquifer Analogs, Saudi Arabia

Excellently exposed Paleozoic Sandstone outcropping strata in central and southern Saudi Arabia provide good outcrop analog to many subsurface formations and hydrocarbon reservoirs and groundwater aquifers. The study of these outcropping rocks provides invaluable opportunity to examine different scale of sedimentary heterogeneity and to understand their impacts on reservoir and aquifer quality and their behavior in the subsurface. This might help to refine and better characterize reservoir and aquifer geological models based on subsurface information.
