Hydrocarbons are reported to occur in all strata of the Earth's crust and are supposed to occur in the cosmic space, too. As to their genesis, there are various authoritative positions. The author's conception does not imply adherence to any of the existing oil origin hypotheses. It is virtually impossible to create a general theory of oil origin. To look at regional oil-source rocks as a sole indispensable prerequisite of oil formation is a wrong position. Oil-and-gas-saturated stratum is an integral interrelated system of rocks (minerals) and fluids (oil, gas, and water). Oil deposit is a "living" fluid-rock system therefore subject to the laws of spontaneous auto regulation. It is necessary that research and practical efforts be focused on study and control of the oilfield "life". The equilibrium-breaking threshold of perturbation for such a fluid-saturated system during the oilfield development can be estimated with the value of formation pressure equal to 5-8 MPa
