The process of developing a geometrically valid description of structures such as stratigraphic beds, folds, faults and fractures and understanding the development of these structures in 3D space and through time is one key component of structural
modeling today. This process may be used to sequentially restore or forward model deformation due to folding, and/or faulting. At present, this type of
structural
modeling is done digitally either in 2D or 3D space using a series of restoration algorithms to mimic rock deformation processes in compressional, extensional, strike-slip and salt tectonic settings. The modeling is applicable from regional to reservoir scale.
