INTEGRATED METHOD FOR COMPOSITIONAL EVALUATION IN OIL WELLS
INTEGRATED METHOD FOR COMPOSITIONAL EVALUATION IN OIL WELLS
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.
