Although a significant increase oil production is expected, the impact of the residual polymer on the produced water cycle should not be neglected. Indeed, after the polymer breakthrough, a significant part of the EOR chemical will be present in the produced fluids, and this may negatively impact the water/oil separation and the water treatment processes. An early review of this scenario provides an accurate vision of potential issues and, above all, enables to anticipate handling difficulties with produced fluids, and identifying mitigation strategies. This paper proposes a specific and comprehensive experimental methodology to assess production risks using laboratory equipment designed to mimic the current separation processes of the Yariguí-Cantagallo field, which were as representative as possible. The objective is to highlight the impact of the residual polymer first on water/oil separation processes with bottle tests, electrostatic dehydration tests, and polymer fouling evaluation on heat exchangers and, second, on water treatment using long-term gravity separation tests, Jar test, flotation column, and walnut shell filtration unit. The assessment considered different scenarios in terms of polymer concentration, water-cut, water composition and initial oil content in the produced water. The compatibility between the polymer and some oilfield chemicals, such as demulsifiers and water clarifiers, was also investigated. The efficiency of these physical and chemical treatments was evaluated by monitoring the separation kinetics as well as by evaluating the quality of the phases with measures of water-in-oil content, oil-in-water content, or water turbidity. For this case study and at laboratory scale, the polymer does not seem to stabilize tight emulsions, rather observing an improvement in water/oil separation kinetics. However, the quality of the separated water is strongly degraded with a higher oil content and some incompatibilities with current demulsifiers which reduce their efficiency have been observed. The risk of polymer precipitation or fouling on heat surface is very low under the experimental conditions tested. The performance of the different water treatment stages is slightly affected in the presence of polymer, even if the water quality remains good. The operational risk assessment conclusions and pending recommendations draw the map of conditions where the residual polymer seems to cause problems or not. This anticipated experimental approach can provide clues and solutions to better manage the impact of the residual polymer in back produced fluids. Adjusting process parameters on existing surface facilities and working on chemical treatment optimization should ensure to produce oil, and release produced water on specifications. This challenge will be one of the keys for technical success and for upholding the expected economic performance of this EOR project.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[RESUMEN Luego de un exitoso programa piloto de inyección de polímeros para recuperación mejorada de petróleo (EOR), Ecopetrol contempla implementar una expansión de la tecnología de EOR en el campo Yariguí-Cantagallo. Aunque, se espera un aumento significativo de la producción de petróleo, no se debe despreciar el impacto del polímero residual en el ciclo del agua producida. De hecho, después de inyectar la solución polimérica, una parte significativa del polímero estará presente en los fluidos producidos y puede tener un impacto severo tanto en la separación de agua/petróleo como en los procesos de tratamiento de agua. La consideración temprana de este escenario proporciona una visión precisa de los problemas potenciales y, sobre todo, permite anticipar las dificultades en el manejo de los fluidos producidos e identificar estrategias de mitigación. Este artículo propone una metodología experimental específica e integral para evaluar los riesgos de producción basada en equipos de laboratorio diseñados para simular los procesos de separación actuales del campo Yariguí-Cantagallo para que sean lo más representativos posible. El objetivo es resaltar el impacto del polímero residual, en primer lugar, en la separación de agua/ petróleo, mediante pruebas de botella, pruebas de deshidratación electrostática y evaluación de depositación de polímeros en intercambiadores de calor y, en segundo lugar, en el tratamiento del agua mediante pruebas de separación por gravedad a largo plazo, test de jarra, unidad de flotación y filtración de columna y cáscara de nuez. La evaluación consideró diferentes escenarios en términos de concentración de polímeros, corte de agua, composición del agua y contenido inicial de aceite en el agua producida. También se investigó la compatibilidad entre el polímero y algunos productos químicos de yacimientos petrolíferos, como demulsificantes y clarificadores de agua. La eficiencia de estos tratamientos físicos y químicos se evaluó mediante el seguimiento de la cinética de separación, así como mediante la evaluación de la calidad de las fases con medidas de contenido de agua en aceite, contenido de aceite en agua o turbidez del agua. Para este caso de estudio a escala de laboratorio, el polímero no parece estabilizar emulsiones compactas y más bien se observa una mejora en la cinética de separación agua/aceite. Sin embargo, la calidad del agua separada se degrada fuertemente con un mayor contenido de aceite y se han observado algunas incompatibilidades con los demulsificantes actuales, reduciendo su eficiencia. El riesgo de precipitación de polímeros o incrustaciones en superficies calientes es muy bajo en las condiciones experimentales probadas. El rendimiento de las diferentes etapas del tratamiento del agua se ve ligeramente afectado en presencia de polímeros, incluso si la calidad del agua sigue siendo buena. Las conclusiones de la evaluación del riesgo operativo y las recomendaciones pendientes exponen las condiciones en las que el polímero residual podría o no causar problemas. Este enfoque experimental puede proporcionar pistas y soluciones anticipadamente para gestionar mejor el impacto del polímero residual en los fluidos producidos. Ajustar los parámetros del proceso en las instalaciones de superficie existentes y trabajar en la optimización del tratamiento químico debería garantizar la producción de petróleo y el agua según especificaciones. Este desafío será una de las claves para el éxito técnico y para mantener el desempeño económico esperado de este proyecto EOR.]]></p></abstract>
