Facies versus Seismic Facies: Case Studies

The presentation will touch upon the comparison of well based and seismic interpretation models on the example of two hydrocarbon fields in Pechora oil and gas basin. It shows that the latter provides much more accurate lateral distribution of reservoirs in the inter well space. On the other hand in complicated polyfacial successions only apriori depositional models provide accurate and geologically reasonable interpretation of seismic data
