Development of oil bearing formations characterized by the values of dissolved gas saturation pressure closest to initial reservoir pressure usually subject to the negative effects of evolving the gas phase and its affect on oil relative permeability in the presence of water and free gas. The question about the reversibility of such process is crucial for the development planning of oil bearing formations in which period of exploitation pressure declined bellow the bubble point. Generalizing the different scientists’ studies the present article justifies the possibility of restoration the productivity potential of such objects by the means of elimination of gas plugs by its resaturation in liquid hydrocarbon phase during the reservoir pressure build-up.
