Análisis Integral de Pozos de los Campos "X" y "A" de La Cuenca Oriente para Optimizar su Producción : Desarrollo del Análisis Integral (Técnico - Económico) de Varios Pozos con Bombeo Electrosumergible (BES), pertenecientes a La Plataforma "B" del Campo "A".

Abstract

Field "A" is producing from the Lower "U" Formation with producing wells completed with an artificial lift system by electrosubmersible pumping; therefore, the optimization techniques were developed according to the current conditions in which they are found and thus determine if it is possible to optimize them by increasing the frequency or suggesting a pump change. In the field 18 wells have been drilled, in which after selecting the wells with a production cut-off date of December 31, 2022, 10 wells were studied, which had the most updated information regarding their production and the events that occurred throughout their productive life. It must be considered that the reservoir is undersaturated, so the analysis is based on a Combined IPR curve that is responsible for determining the oil production, until reaching the bubble point pressure, and from that point the gas production. What is sought is to maintain production above the bubble point; however, according to the production histories presented, an exponential decline was determined in which imminently in some cases will come to produce from the gas-cap. In the economic analysis carried out for each well, it was established to increase the frequency of the pumps that according to their design have the capacity to lift more fluid working in optimal conditions that do not affect their efficiency, achieving an increase in oil flow to a total of 464.85 bpd among all the wells. For Well B1 a pump change was suggested to establish an optimization alternative in which profitability was observed in the first month of production and in parallel, start producing from the gas-cap, implementing new completion techniques, and considering the decrease of the pump's useful life. Therefore, for most of the wells that showed high oil flow rates, we sought to maintain their operating conditions and not alter the scenarios in which they are located, in addition to the frequency of the pumps.
