3D surface shape conformance QC in geological model building

Surface “shape” conformance in geological models is important for structural grids, tying grids to horizontal wells, well planning, geosteering, property modeling and volumetric calculations. We outline several metrics applicable to reservoir model surface conformance measurement that allow for rapidly highlighting problem areas and correcting reservoir shapes relative to highly deviated and horizontal wells. This allows geoscientists to QC data from 1000’s of legacy wells while updating the surfaces in real-time during geosteering resulting in a “living” model that can also serve as an input for reservoir simulation.
