Study of methods of hydrocarbon recovery enhancement from the depleted oil fields.
Vol. 30, no. 1 (2013), s. 127-142, 
The article deals with the optimization of existing development system and oil recovery factor enhancement through the involvement to the development of productive bed areas with significant remaining oil reserves by using the hydrodynamic models of filtration processes of formation fluids in heterogeneous beds on the example of the sandstone deposit of the Boryslav field. The calculations for the different variants development in order to select the most rational one of the further development of a field were made. The task of the optimization was performed according to the criteria of the highest value of oil recovery factor.
