Earth Modelling Using Distance-Fields Derived by Fast Marching

D024 Earth Modelling Using Distance-Fields Derived by Fast Marching S.A. Petersen* (Hydro Oil & Energy) Ø. Hjelle (Simula Research Laboratory) & S. Lund Jensen (Hydro Oil & Energy) SUMMARY A fast methodology to distribute properties of any geological complexity in 2D and 3D space is presented. The method uses combinations of distance-fields (and other attributes) derived by Fast Marching level set techniques from simpler geometries in 2D and 3D to populate space with relevant physical properties. The paper presents how the methodology works for different geometries and the result of applying combined distance-fields to describe realistic and complicated geological situations.
