    Περίληψη
    The current study describes the effect resulted from the existence of potential barriers at the history matching and future production prediction processes during the reservoir simulation studies of a producing field. The study area is located at the Norwegian part of the North Sea and constitutes a segment of the Gullfaks field operated by Statoil ASA.
    The majority of sandstone reservoirs is not homogeneous in terms of lithology and may contain significant amounts of shale. Although seismic technology can allow some assistance for the delineation of those amounts of shale, in most cases are below seismic resolution and not detectable at reservoir locations where there are no well data. Even if there are indications for the shale sequences from wells, their quantitative spatial distribution is a high uncertainty task but its knowledge is of high importance for the understanding of the lithological effect on transport properties and as a result to the estimation of recovery factors.
    The model used for the analysis has been created from Statoil ASA and it has been modified for the purposes of the present project in terms of barrier application. The software ECLIPSE was used for the simulations and the production data results were further processed for the quantitative calculation of the Root Mean Squared Error % between the recorded production data and the simulated ones used during the history matching and forecasting.
    Based on the results from the application of various types of barriers it can be observed that for the individual wells the error is proportional to the size of the barriers with the barriers that cover all the grid layers, to be characterized from an error increase with the increase of the barrier size while it is insignificant for small size barriers that cover individual grid layers. The latter ones tend to be the most realistic barriers but can be identified only at the areas with well data. Regarding the cumulative oil field production, the error for both types of barriers, those that cover all the grid layers and the ones cover individual layers, is significantly low or equal to the value zero.
