Flow behind the casing has normally been identified and quantified using production logging tools. Very few applications of pressure transient analysis, which is much cheaper, have been devoted to determining compromised cemented zones. In this work, a methodology for a well test interpretation for determining conductivity behind the casing is developed. It provided good results with synthetic examples.

El flujo detrás del revestimiento se ha identificado y cuantificado normalmente utilizando herramientas de registro de producción. Se han efectuado muy pocos desarrollos de análisis de presión transitoria, que son mucho más baratas, para la determinación de zonas cementadas comprometidas. En este trabajo, se desarrolla una metodología para la interpretación de las pruebas de pozo para la determinación de la conductividad detrás del revestimiento y se prueba con buenos resultados con ejemplos sintéticos.
