Challenges around Integration of Stochastic Inversion in the Eldfisk Geomodel

G020 CHALLENGES AROUND INTEGRATION OF STOCHASTIC INVERSION IN THE ELDFISK GEOMODEL N. HALLER 1 O. KNOTH 2 Abstract 1 Acoustic impedance (AI) is a key parameter in reservoir characterization workflow in particular because this rock property belongs to both geophysical and geological world and so intrinsically integrates data. During a one-year project dedicated to the update of the Eldfisk reservoir model AI was used intensively by all geoscientists to guide the layering definition and the porosity distribution. The reservoir at Eldfisk like the neighbouring chalk fields Ekofisk and Valhall is poorly seismically imaged in compressional mode due to the presence
