Jubarte field production enhanced with wellbore ESP

摘要

Through technological advances in ultra deepwater production, the highest horsepower-equipped electric submersible pump (ESP) to date was installed in the 1,400-m (4,593-ft) JUB-6 subsea well in the Jubarte field, offshore Brazil. The system is composed of a 1,200 hp motor and a pump capable of producing over 22,000 b/d of heavy oil (17° API). High flow rates and a longer subsea step-out were the drivers for selecting an ESP system as the artificial lift method for the project Reliability is one of the main concerns of ESPs, and proper selection of the system for the application was critical for the run life of the equipment
