Abstract S-Field stands out as one of Indonesia's largest mature oil fields, boasting a history dating back to its development in 1952. Over the past four years, an average of 450 rig activities annually has been dedicated to repairing and resizing the 1000 Electric Submersible Pumps (ESPs) employed for artificial lift operations. These pumps are crucial for achieving optimal flowrate production, with production targets ranging from 100 to 15,000 Barrels of Fluid per Day (BFPD). However, the extensive rig activity presents significant challenges in managing artificial lift performance, inventory, and energy consumption efficiently. To address these challenges, the introduction of Compact Wide Range Electric Submersible Pump (CWR ESP) Technology offers a breakthrough solution. This innovative technology enables pumps to operate within an exceptionally wide flowrate range, from 500 to 3000 BFPD. Achieving this remarkable range is made possible through the utilization of high rotational pump speeds, driven by permanent magnet motors, ensuring energy efficiency throughout operation. In October 2021, a set of CWR ESP D2000HS pumps were deployed, marking a significant milestone. These pumps seamlessly transitioned from conventional speeds of 3000 rpm to an impressive 7000 rpm without encountering any reliability issues. Notably, the CWR ESP demonstrated its capability to produce a flowrate ranging from 600 to 2400 BFPD through periodic speed adjustments alone, eliminating the need for rig intervention. This saved valuable time, preventing three days of potential production loss, and eliminating rig fuel consumption. Impressively, the CWR ESP exhibited reliable performance for over 700 days before proactive replacement was deemed necessary. Comparatively, the tested CWR pump surpassed the median ESP run life at Sinam Field by 104 days and outperformed four conventional ESP types. Additionally, it recorded 8.7% reduction in power consumption compared to conventional ESPs with identical flowrates. The demonstrated technical prowess and reliability of CWR ESPs present a compelling alternative for artificial lift operations. Beyond enhancing operational efficiency and reducing carbon emissions through rig optimization and energy-efficient operations, the CWR's benefits extend to inventory rationalization, particularly in large, mature field operations.
