In most cases, the existing simplified geological models do not correspond to the current level of geological knowledge. The authors also faced such contradiction when calculating the reserves of BP12 horizon of the Vyngayakhinskoye field.The productive layers of the BP12 horizon were plane-parallel according to well logs in previous works. However, the new drilling started to contradict the existing geological model.Clinoform structure was confirmed as a result of a new seismogeological interpretation of the horizon internal structure. Different seismic attributes taken directly from the reflective horizons BP121, BP122 and BP123 (BP15) used to outline lithological bodies. Well correlation was performed taking into account all seismic data.Generalized facies maps for the layers give a presentation about the distribution of the thickness and reservoir properties in traced lithological bodies.A more correct estimation of hydrocarbon reserves of BP12 horizon was made using geological model based on local facial patterns.
