Using this technology is possible to obtain relevant data from the reservoir such as remaining oil accumulations, estimate volumetric sweep efficiency, define reservoir heterogeneities, identify flow channeling, and determine residual oil saturation (Sor). This technology has been one of the most useful tools for reservoir characterization for several decades. The tracer is injected in the injector well and then monitored in the producer wells through the tracer concentration measurements. Although many tracer studies have been documented for reservoir characterization, the available information and methodologies related to the design, implementation, and interpretation of tracer tests are limited or confidential. The goal of his article is to show a methodology for the design, execution, and interpretation of interwell tracer tests, which includes procedures for field implementation, sampling, and monitoring of these tests. Laboratory analysis using ultra-high-performance liquid chromatography is described in the experimental evaluation of tracer tests. Additionally, for a better understanding of the technology, examples of laboratory and field cases are presented.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[RESUMEN La tecnología de trazadores se ha utilizado en la industria petrolera para investigar el comportamiento de flujo y las propiedades que controlan los procesos de desplazamiento del gas y del aceite en el yacimiento, para identificar acumulaciones remanentes de crudo, evaluar eficiencia volumétrica de barrido, definir heterogeneidades del yacimiento, identificar problemas de canalización en inyectores y determinar saturación residual de aceite (Sor). Esta tecnología es utilizada como herramienta para caracterizar yacimientos, consiste inicialmente en la inyección del trazador a través de un pozo inyector, seguido por un monitoreo de la concentración de trazador en los pozos productores previamente definidos. En Colombia se han desarrollado diferentes estudios de trazadores para la caracterización de yacimientos, sin embargo, la información y metodologías relacionadas con el diseño, implementación e interpretación de las pruebas de trazadores es limitada. Debido al alto costo que representa implementar este tipo de pruebas, limita su aplicación en procesos de recobro mejorado, especialmente en escenarios de precios bajos del crudo. Este artículo presenta una metodología para el diseño, ejecución e interpretación de trazadores entre pozos, que incluye la implementación de este tipo de pruebas en campo, el muestreo y seguimiento y el análisis en laboratorio a partir de cromatografía líquida de ultra alta resolución. También se incluyen conceptos generales, la clasificación de los diferentes trazadores comercializados en el mercado actual y se presentan dos casos de aplicación de esta metodología a nivel laboratorio y en campo.]]></p></abstract>
