Abstract
Description
Llevar a cabo una prueba de ascenso de presión en un pozo, se convierte en una decisión difícil de tomar debido al cierre y a que estos trabajos requieren un procedimiento que implica costos operacionales, sin embargo, se hacen necesarios para obtener información acerca de la formación y del pozo en estudio.
Con el fin de disminuir los costos operacionales y obtener un flujo estabilizado antes de realizar el cierre, este trabajo presenta una metodología que puede ser implementada en pozos con bombeo mecánico que se encuentran completados con bomba de subsuelo inserta.
Carry out a buildup pressure test in a wellbore, becomes a difficult decision to make because of the well has to be close and also that this test requires a procedure that involves high operational costs, however, it is needed to obtain information related to the formation and the well in study. With the purpose of reducing operational costs and obtain a stabilized flow before closing the well, this paper presents a methodology that can be implemented in wells with mechanic pump that are completed with a subsurface insert pump.
