Periodicity of oil recovery changes in deposits as result of natural factors influence
Purpose. The purpose of research is to detect the presence of periodicity of oil recovery from reservoirs, related to natural factors which affecting on the fluid regime of crust and on oil recovery too. Methodology. The method is based on the analysis of the fluid regime of crust, study the dynamics of changes of the flow rates, identifying periodic components over time in the oil production on the actual and literature data. Results. We analyzed the nature of changes of oil production in fields of Azerbaijan and Russia.
