Operator
An operator in China had a well operating with standard rod lift equipment. The well’s data suggested higher production potential. Apart from its limited production, the well’s rod lift system failed every 150 days. This downtime caused the operator to incur costs related to constant workovers, resulting in increased operating expenses and lost oil production. The operator tried a few different measures to solve the issues—such as injecting corrosion inhibitors—but the root cause of failure could not be identified, and every time a sucker rod was installed it would break a few months later. Baker Hughes engineered a fit-for-purpose approach that included a 400 series electrical submersible pumping (ESP) system with a
desired deeper pump target depth
™
high temperature motor, a GM Performance Series gas separator, a Centinel™ downhole sensor, and a microDRIVE™ variable speed drive (VSD). The ESP system was installed at a measured depth of 9,186 ft (2800 m). The ESP system has delivered faultless performance since installation, with 21% instant increased production and 28% total increased production. This improvement in performance has resulted in a gain of USD 600,000* in the first 10 months of operation. With no failures to date, the operator has not incurred any workover costs. The Baker Hughes ESP system is still in operation and has already doubled the run life vs. the rod lift system. *Revenue calculated at USD 100 per barrel of oil
Baker Hughes solution Operator
approached Baker Hughes for an alternative artificial lift solution
Engineers
from Baker Hughes analyzed system requirements
Baker Hughes suggested and subsequently installed conventional ESP system solution
Production
increased by 21% with ESP system vs. rod lift
ESP
system extended run life; at press time, current ESP system has been running for 300+ days without failure
ESP
system increased revenue USD 600,000* in the first 10 months
