Annotation:
The results of a study on a model of a heterogeneous multilayer oil-saturated reservoir, the effect of free gas formed due to degassing of oil and free gas formed after the implementation of water-gas stimulation technologies on the reservoir are considered. Measures are proposed to reduce the volume of free gas by changing the injection regimes and regulating the reservoir pressure.
