Abstract

A021 Petrophysical Seismic Inversion for Porosity and 4D Calibration on the Troll Field T. Coleou* (CGG) A.J. van Wijngaarden (Hydro) A. Norenes Haaland (Hydro) P. Moliere (Hydro) R. Ona (Hydro) & J.L. Formento (CGG) SUMMARY We present an application of petrophysical seismic inversion a method driven by petro-elastic models updating a fine-scale geological model in depth to make it fully compatible with pre-stack seismic measurements on the western part of the Troll Field in the North Sea. The results are being evaluated for infill drilling and for 4D inversion to determine the remaining oil in the thin oil leg. EAGE
