Pulse-Test Interpretation for Badri Field

Abstract

This paper shows the results of a Pulse Test conducted in Egypt's Badri Field. The test was conducted to understand the degree of hydraulic communication within the reservoir and to check a suspected fluid migration towards the nearby EI-Morgan Field. The test involved 6 wells, including the active well. The pulses were created by an alternate sequence of injection and shut-in periods of 36 hours each. The resulting pressure pulses were monitored in the observation wells for 12 days.Pulse Test Interpretation for Badri Field SPE25632 OBJECTIVESIn this paper, the results of the Pulse Test conducted in Egypt's Badri Field are presented. The objectives of the test were to determine the degree of hydraulic communication between the wells and to find a mathematical model that is capable of describing the dynamic behavior of the reservoir section investigated by the test. One of the objectives was to check the suspected fluid migration from the Badri-Belayim to the nearby EI-Morgan Field. PULSE TEST PROCEDUREThe test was conducted in the Badri Field, Belayim formation. The location map of the Badri and El-Morgan Fields, along with the top structure maps is shown in Fig. 1. The test involved six wells, Badri C1, C3, C4, C5, C7 and C8. Well C3 was the injection well and well C5, which was a producer, was shut-in before the test. Crystal gauges with extended memories were run in the observation wells C1, C4, C5, C7 and C8, and were set 20 feet above the top perforations. The layout of the production and injection wells are shown in Fig. 2.
