In present paper, authors discuss stability conditions of stationary filtration below bubble point pressures in the case of non-monotonous dependence of the relative phase permeability of fluid on the gas saturation. It was shown the existence of regular auto oscillations evolving into deterministic chaos through the induction and degradation of quasi-regular flow.
