This concern recently motivated the development of dedicated inversion or matching techniques for identifying models consistent with all collected data. The methodology presented in this paper makes it possible to map petrophysical properties such as facies, porosity and permeability into reservoirs from production data and seismic attributes. It is successfully applied to a synthetic case describing a heavy oil field produced from steam assisted gravity drainage. This case study generated from a real case shows how to design the inversion methodology to match the entire set of available data. A few key points are highlighted since they drive the success of the proposed matching methodology. First, parameterization is essential. It must allow for locally varying petrophysical properties from a reduced number of parameters. Second, this study stresses the need for alternative formulations for quantifying the mismatch between reference seismic attributes and simulated seismic attributes. Last, two methods are compared for integrating reference seismic attributes either in time or in depth (after a time-to-depth conversion). In the case studied, it is shown that the two approaches are equivalent since time-to depth-conversion error is quite small. 2 Oil and Gas Science and Technology 67 ARTICULO Tillier, E. 53208 Le Ravalec, M. 53127 Da Veiga, S. 53209 187708 187708 0 0 0 0 255527 BAAB BAAB 2026-03-06 200059851 0 200059851 2026-03-06 00:17:42 2026-03-06 ARTICULO
