The present invention relates to an integrated method to identify the reservoir compartmentalization and characterize samples of different compositional gradations and types of operation (PVT and DST) through the ESI (−) and APPI (+) FT-ICR-MS techniques in combination with the application of machine learning algorithms. In this way, the present invention presents an integrated method for compositional evaluation in oil wells to: (i) analyze the compositional variation of the polar components in reservoirs; (ii) study the molecular distribution in reservoirs with varied thicknesses; and (iii) explore the composition of the polar components as molecular indicators for understanding compartmentalization and lateral and vertical connectivity between the fluids in reservoirs.
