COMPARACIÓN DE MÉTODOS ANALÍTICOS PREDICTIVOS DEL COMPORTAMIENTO DE PRODUCCIÓN EN PROCESOS DE RECUPERACIÓN SECUNDARIA EN UN SECTOR MODELO APLICACIÓN CAMPO COLOMBIANO

Abstract

In each of the operations performed in the oil industry, there are tools that provide information to the engineer and let to know the behavior of processes and the effect to the proposed objective to evaluate the performance of project. For the characterization of the injection ¿ production system of the sector model objective of this study, a commercial Software was used, which facilitates the visualization, analysis and monitoring, this tool handling a large volume of information required to develop an understanding of the physical mechanisms and the behavior of the reservoir. The analytical models are created by a set of equations (generally differential) that represent the system which must be solved at different conditions. An optimization model, which provides the best strategy that the system must implement to work better in agreement, with some measure of performance established in the target function and satisfying the diverse conditions of the problem, established in ¿the restrictions¿, must be built. With help of the commercial software, the different injection patterns were created, which were characterized by its porous volume, its initial and residual saturations of oil and the petro physical parameters. Every element of flow was analyzed to know the influence of the injector wells on the producers. After this characterization, the efficiency of the process of secondary recovery in selected area is evaluated. The final result of the study was a comparison between the three analytical methods and the evaluation of the representation of each one of the methods in the model.
