The article deals with the results of experiments on influence of water content of recovered product in 50, 70 and 100 % and pressure decrease gradient 0.003; 0.006; 0.012 and 0.022 MPa/m on oil recovery factor in production of oil via compositional system (CS) from bedded-heterogeneous by permeability oil stratum. It was revealed that with application of CS bank, consisting from surface-active agent with concentration of 0.2-3 % diesel-alkaline waste, in bedded-heterogeneous formations oil recovery factor decreases by increase of water content of recovered product and temperature reduce gradient.
