Any reservoir characterization calls for a prior accurate estimation of the depths of all layering surfaces. Indeed the layer surfaces determine hydrocarbon volumes in place and define the envelope used for subsequent reservoir studies. Many algorithms exist for estimating a single layer surface, typically the layer top. But fewer algorithms can deal efficiently with multiple layer surfaces mapping. This thesis presents a new methodology to jointly simulate multiple layer surfaces conditional to seismic data, all well markers and all deviated well paths. The proposed method uses velocity data from wells and correlated secondary information to simulate velocity in 3D for mapping layer surfaces. Because the approach proposed considers velocity as the principal variable, it is consistent with commonly available geophysical data, such as seismic velocity and impedance inversion. In a stochastic mode, the method results in multiple equiprobable realizations of the layering surfaces, enabling an assessment of uncertainty in the reservoir volumetrics. To extensively test the performance of the proposed method, a synthetic reference data set was generated to mimic a multi-layer fluvial channel reservoir. Limited well data and seismic data were used as input information. A case study using the proposed method and a traditional surface mapping algorithm was presented to demonstrate the performance of the proposed approach.
