Uncertainty reduction through geologically conditioned petrophysical constraints in joint inversion Jérémie Giraud, Evren Pakyuz-Charrier, Mark Jessell, Mark Lindsay, Roland Martin and Vitaliy Ogarko Right Running Head: Conditioned petrophysical constraints Geophysics (2017) 82 (6): ID19-ID34. The integration of probabilistic geological modeling permits more accurate retrieval of model geometry, and better constrains the solution while still satisfying the statistics derived from geological data. The analysis of statistical indicators at each step of the workflow shows that 1) the inversion methodology is effective when applied to complex geology, and 2) the integration of prior information and constraints from geology and petrophysics significantly improves the inversion results while decreasing uncertainty. Lastly, the analysis of uncertainty to the integration of the conditioned petrophysical constraints also shows that, for this example, the best results are obtained for joint inversion using petrophysical constraints spatially conditioned by geological modeling.
