The present invention comprises a method of Enhanced Petroleum Recovery (EPR) combining technical, economic, environmental and social effectiveness to increase the recovery factor of onshore or offshore fields having a high degree of exploitation, more precisely through the use of a substance miscible with the diverse types of petroleum of low fluidity found in various regions. More specifically, the present invention refers to the use, of solvents such as light liquid fractions of petroleum, for example diesel oil and gas oil, a light petroleum, and the essential oils derived from renewable sources such as for example biodiesel, used pure or mutually admixed in any proportion, for injection into a geological formation through an injection well, there resulting a final mixture (petroleum/injected solvent) presenting much lower viscosity and much greater fluidity than the original petroleum, having an impact throughout the petroleum production chain. The present patent presents real gains in all phases of the production chain. For the purposes of the present invention biodiesel is understood to be oil having characteristics similar to diesel produced from mineral sources, however having been produced from renewable sources, usually agricultural sources.
