These issues have led to strong emulsion problems and operational issues with many wells' electro-submersible pumping systems (ESPs). In response, companies have decided that all wells with ESP equipment in the T2 formation should undergo downhole treatment using capillary scale inhibitors and fluidity improvers. However, due to operational and design constraints, some wells only have one capillary, making it difficult to prioritize and decide on a single treatment. Ecopetrol and ChampionX have collaborated to develop a new flow improver that can be applied with the scale inhibitor in the same capillary without causing incompatibility or affecting product performance. This innovative solution was implemented in five wells, using 600 ppm for the flow improver, and 25 ppm for the scale inhibitor, resulting in a significant increase in crude oil production by up to 79%, USD 55.000 in cost savings in capillary system installation, 29% energy savings, and reduced emissions. This successful application is innovative and unique in Colombia, and it sets an example for other fields facing similar challenges in the country, offering a promising approach to leverage heavy crude oil production and transform the future of these fields.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[RESUMEN El futuro de la producción del campo Apiay es la formación T2 la cual tiene grandes retos a enfrentar, el primero, la alta tendencia incrustante del fluido, y segundo, la producción de crudo pesado, esto ha generado en muchos pozos problemas de emulsiones fuertes, sobre esfuerzo en las etapas y motor de los sistemas de bombeo electro sumergible, lo cual ha ocasionado fallas y baja producción en estos pozos. Por lo anterior, se decidió que todos los pozos donde se bajarán equipos de bombeo electro sumergible y produjeran de la formación t2, debían tener tratamiento en fondo mediante capilar de inhibidor de incrustaciones y mejorador de fluidez, debido a que los dos productos químicos son de bases diferentes, requieren ser aplicados en capilares de forma individual. Sin embargo, existen varios pozos que por temas operacionales y de diseño que solo tienen un capilar disponible, lo cual genera una situación problema en la operación al tener que priorizar y decidir un solo tratamiento a aplicar, generando problemas en las condiciones operacionales de los pozos. Por consiguiente, Ecopetrol y ChampionX se reunieron para trabajar conjuntamente en el diseño de un nuevo mejorador de fluidez que pudiera aplicarse con el inhibidor de incrustaciones en el mismo capilar sin generar incompatibilidad ni afectar el desempeño de cada producto. Esta aplicación se realizó en 5 pozos, utilizando una dosis de 600 ppm para el mejorador de fluidez y 25 ppm para el inhibidor de incrustaciones, obteniendo resultados positivos, entre los que se encuentran: aumento de la producción de crudo hasta en un 79%, ahorro de USD $55.000 en costos asociado a la instalación de un capilar y optimización en el desempeño de los equipos de bombeo electro sumergible, permitiendo un 29% de ahorro energético y una reducción similar en emisiones. Esta aplicación es innovadora y única en Colombia, por lo que es ejemplo para seguir en otros campos que estén atravesando por los mismos problemas, y de esta forma apalancar la producción de crudos pesados y el futuro de estos campos.]]></p></abstract>
