A novel technique for 3-D constrained, parametric, post-stack seismic inversion is presented. Deterministic integration is performed of seismic data, log data (for instance sonic and density) derived from either vertical or deviated wells, formation tops and time interpretations. One horizon in depth is used as a reference surface for the tirne-to-depth conversion. This study shows the potential benefits of the method. The properties of this inversion method are exemplified by a feasibility study using data from the Snorre Field in the North Sea. The goal of this study is to optimally define the geological model for the reservoir formations using this 3-D inverse modelling tooI. As a result of this inversion study detailed sonic and density models are derived, both in two-way travel time and depth.
