The benefit of a 3D Modeling chain in Exploration Production is demonstrated on a real case study. It consists in constructing a Shared Earth Model integrating data and interpretation from geophysicists, geologists and reservoir engineers. Fast and easy updating of consistent 3D information is a key aspect. The shared earth model is the integration of the following speciality models:3D Structural Model3D Sedimentary Model3D Reservoir Model As it contains all reservoir data, it is the reference model for:–Integrating new data–Integrating analysis form structural unfolding, foward sedimentary modeling,…–Checking new or alternative interpretations–Uncertainties–. . . This case study highlights that a consistent model can only be achieved through a full 3D interdisciplinary team work. P. 741
