Box 220 N-4098 Tanager Norway 2 Ødegaard Norge A/S Norway Abstract This paper describes how simultaneous full elastic seismic inversion carried out over a chalk prospect has been used to derive both acoustic impedance cubes for part of the overburden and the reservoir as well as delivering a detailed 3D velocity cube that is consistent with the impedance cube for the same intervals. This simultaneous inversion ensures that there is consistency between
