| contents | Experimental study and calculations of the near critical behavior of a synthetic fluid in nitrogen injection Juan-Carlos-M. Escobar Remolina Carlos-Alberto Coronado Parra Ingeniería gas injection phase behavior critical region retrograde region equation of state (EOS) In recent years, the use of nitrogen has increased as gas injection to recover oil fluids near the criticalpoint. The behavior of hydrocarbon mixture phases in the critical region shows very interesting complexphenomena when facing a recovery project with nitrogen. Therefore, it is important to have experimentalinformation of the PVTx thermodynamic variable, often scarce, for this type of critical phenomena.This paper reports the experimental measures of the volumetric behavior and phases of synthetic fluid in anitrogen injection process. The experiment was performed at laboratory scale, and it obtained variations onthe saturation pressure, gas oil ratio, density and composition of the hydrocarbon phase when nitrogen wasinjected at molars of 10, 20, 30 and 40% on different volumetric portions of the mother sample. In addition,the data obtained experimentally was used to demonstrate the capacity of tune to compositional models.The data provided represents a valuable contribution to the understanding of phenomena associated withretrograde and near critical regions, as well as their use in tuning and developing more elaborate modelssuch as Cubic Equations of State (EOS). It is worth highlighting the importance of this data in the potentialprocesses of nitrogen, CO2, and lean gas injection, which require knowledge of the gas-oil ratio, saturationpressures, density and composition of the fluid in current production. The identification of the phenomenashown, represent a potential application to the modeling of displacements and maintaining the pressure inthe improved recovery when scaling up the laboratory data to the field / reservoir conditions. 2005 artículo científico 0122-5383 https://www.redalyc.org/articulo.oa?id=46530109 en http://www.redalyc.org/revista.oa?id=465 CT&F Ciencia, Tecnología y Futuro application/pdf ECOPETROL S.A.
