The hybrid solar thermal enhanced oil recovery system with an oxy-fuel combustor is an enhanced oil recovery system utilizing solar thermal enhanced oil recovery during the daytime and utilizing an oxy-fuel combustor in the nighttime. A solar heater is used for the solar thermal enhanced oil recovery, generating steam injected into an oil field having an oil well for enhanced oil recovery. During the nighttime, when solar heating is not available, an oxy-fuel combustor produces carbon dioxide and nitrogen. The carbon dioxide is injected into the oil field for miscible enhanced oil recovery and the nitrogen is separately injected into the oil field for immiscible enhanced oil recovery.
