Taking Better Advantage of Fold Axis Data to Characterize Anisotropy of Complex Folded Structures in the Implicit Modeling Framework

When too few field measurements are available for the geological modeling of complex folded structures, results implicit methods typically exhibit an unsatisfactory bubbly aspect. However, in such cases, anisotropy data often readily but not fully exploited. Among them, fold axis a straightforward indicator this local direction. Focusing on so-called potential method, work aims to evaluate effect incorporation into process. Given locally sampled data, paper proposes use second-order derivatives scalar addition existing first-order ones. The mathematical foundation approach is developed, and respective efficiencies both kinds constraints tested. Their integration impact discussed based synthetic case study, thereby providing practical guidelines geomodeling tool users parsimonious structures.
