This article discusses methods for conducting calculations for specific reservoir parameters, taking into account the patterns of pressure distribution in the reservoir, and presents the results of a literature analysis. Pressure distribution in the reservoir, in the context of oil production, is represented as the difference in energies or the released energy required for the movement of oil within the reservoir and its extraction to the surface. Reservoir energy is divided into natural and artificial energy, in the case of external influence (from the surface). These energies manifest in the form of potential energy, i.e., positional energy, and elastic deformation energy. The main sources of reservoir energy are: the pressure energy of edge and bottom waters, the pressure energy of gas in the gas cap, the expansion energy of gas released from oil initially dissolved in it, the elastic energy of rocks and fluids, and gravitational energy (gravity). These forces can act together or separately. Thus, the energy resources of the reservoir are characterized by the pressure existing within it. The higher the pressure, the more effectively the
