Desarrollo del mapa de presiones de la arena “T” del campo Shushufindi mediante el análisis de pruebas de presión

Abstract

By reinterpreting the pressure test data developed in the wells of the Shushufindi field of the "T" sand in its production life, the pressure behavior was compared over time. The processing of restoration test data and other information was executed using the Saphir NL software. 91 pressure tests were analyzed, selected according to parameters such as well closing time, radial flow identification, stable previous production, among others. The field has a total of 215 tests, of which only 42.33% had available data that were analyzed and entered into the Saphir NL software for the generation of the isobaric map of the "T" sand. In each well the reservoir pressure was estimated at December 2018. In this way it was concluded that in the northern zone, with the analysis of 29 pressure tests, resulted in an estimated current reservoir pressure of 2,038 psi. ; the central zone, with 19 tests analyzed, an average reservoir pressure of 1 990 psi, being the zone with the lowest pressure; the southern zone with 14 tests analyzed, has an average reservoir pressure of 2 126 psi and finally, the south-west area has 8 tests analyzed, an average reservoir pressure of 2 329 psi is estimated
