APLICACIÓN DE UN TRATAMIENTO QUÍMICO PARA EL CONTROL DE PARAFINAS EN LA TUBERÍA DE PRODUCCIÓN EN EL CRUDO DEL CAMPO ESCUELA COLORADO

Abstract

This paper presents the implementation of a chemical treatment in a pilot well of the Colorado Field to prevent the precipitation and deposition of paraffins in the production tubing. Such treatment was previously developed in the laboratory, which proved to be effective, thus reducing the crystallization point. Was selected the Col-75 as pilot well, because he met a number of criteria needed for successful development of the project. Based on experimental design, it was determined the number of tests was performed, and the influence of chemical treatment volume and the recirculation time on the point of crystallization of the crude oil. The different treatment applications were made every eight days, taking crude samples before and after. Those samples were testing in the laboratory in order to evaluate the effectiveness of the chemical treatment. With the results it was found that the best treatment to prevent paraffin deposition inside the production tubing is having the lowest volume of treatment and recirculation time, which is economically viable compared with cleaning work of the well as corrective method. We conclude that treatment can be extended to other wells of the Colorado Field, but it is recommended to monitor and control in order to evaluate its effectiveness.
