Often, interpretation of interference tests is performed for systems acting under radial flow regimen conditions by means of conventional straight-line method, type-curve matching and TDS technique. For linear and spherical flow cases, the interpretation of interference tests is performed by the conventional analysis and type-curve matching. These procedures do not allow verification of the estimated parameters; therefore, this paper presents the formulation of a more practical, useful and accurate methodology which is achieved based upon the determination of characteristic features found on the pressure and pressure derivative versus time log-log plot with the purpose of developing analytical expressions for the interpretation of interference tests under spherical and linear flow conditions. These equations were successfully verified by their application on synthetic tests.
Normalmente, la interpretación de las pruebas de interferencia se realiza en sistemas que actúan bajo condiciones de régimen flujo radial utilizando análisis convencional de la línea recta, curvas tipo y técnica TDS. Para los casos de flujos lineal y esférico, la interpretación de pruebas de interferencia se realiza mediante el método convencional y el ajuste con curvas tipo. Estos procedimientos no permiten verificación de los parámetros estimados, y por ello en este trabajo se presenta una formulación de una metodología más práctica, útil y práctica mediante el uso de rasgos características en el gráfico logarítmico de la presión y derivada de presión contra tiempo, que permitan desarrollar expresiones analíticas directas usadas para la caracterización del yacimiento en pruebas interferencia en condiciones de flujos esférico y lineal. Estas ecuaciones se verificaron satisfactoriamente mediante a su aplicación a pruebas sintéticas.
