...Conclusions and main results In order to create a reliable geological model, determine the FWL, transition zone and WOC, an integrated multidisciplinary approach was applied in the course of work, including: Results of seismic facies analysis and sequence stratigraphic interpretation...

... Abstract The developed transition saturation zone and the presence of free water above the accepted level of OWC, which is usually characterized by undersaturated reservoirs, greatly complicates the development of deposits and requires updating the geological model based not only...

... are widely used during well planning and geological modeling, are often not taken into account in the geosteering process. This is due to the fact that the drilling results do not always confirm the forecast made with the use of seismic data. In order to increase the convergence of wells and seismic data...

... Abstract Existing approaches to the creation of hydrodynamic model based on a single implementation of the geological model, lead to difficulties in adaptation – there is a need for additional artificial adjustments of the initial data, and, as a consequence, inaccurate assessment...

There are interrelations between petrophysical and geological uncertainties, which significantly affect on the reservoir dynamics. Hence, changes in one of the parameters during HM should influence...
