Abu Dhabi Oil Co., Ltd. (ADOC) is currently operating three oil fields offshore Abu Dhabi; Mubarraz Field, Umm Al-Anbar (AR) Field and Neewat Al-Ghalan (GA) Field. In the Mubarraz Field, ESP's (electrical submersible pump) have been installed as an IOR method. The first ESP was installed in 1975 and over 320 ESP's have been installed and operated since then. At present, all 44 wells are ESP wells, and approximately 10 workovers are carried out annually. Numerous improvements have been applied to the ESP assembly to increase the lifetime of the ESP's. Currently, the average running lifetime is 3 to 4 years, and the maximum running lifetime is 4,077 days (11.2 years).
