Generación de correlaciones de presión, volumen y temperatura para el petróleo de los activos andes, auca y repsol.

Abstract

The PVT correlations are necessary to be able to estimate the properties of the fluids (water, gas, oil), modified correlations were generated since there is not the same number of samples and handling of temperature parameters, API and pressure with respect to the existing correlations. For the Andes, Auca and Repsol Assets, the validation of 96 PVT reports was carried out, generating the modification of the correlations with the help of the Solver complement of Microsoft Excel and statistical methods (AARE, ARE and r). Correlations were selected for the properties: oil volumetric factor, bubble pressure, gas - oil ratio, compressibility and oil viscosity; the correlations of the literature were made for the properties of the oil above or below the bubble point and API rank classification. Therefore, the correlations selected after their modifications were implemented in the CORRELACIONES J & Z application.
