Reducing Carbon Footprint by Deploying High-Performance Electric Submersible Pumps and Enabling Real-Time Digital Optimization

This case study presents a comprehensive evaluation of how the integration of advanced electric submersible pump (ESP) technologies, efficient gas handling devices, high-efficiency induction motors, and continuous real-time digital surveillance can drive both operational efficiency and sustainability in upstream oil production. The focus is on 22 wells operated by SOGC, Inc. in the Williston Basin, USA, between June 2024 and April 2025. The primary objective of this study is to illustrate how these technological advancements, combined with proactive remote operations, can minimize downtime, extend ESP run life, and significantly reduce the carbon footprint associated with oilfield operations. 
The methodology involved a comparative analysis of production data and downtime before and after the digital service center assumed full control of remote interventions for the operator. The study meticulously tracked ESP performance indicators, such as mean time to failure (MTTF), average run life, and uptime, to assess the impact of digitalization and proactive interventions. Environmental impact was quantified by translating operational improvements into tons of CO2e emissions reductions, directly linked to the prevention of field trips and workovers. The analysis also considered the broader implications of these operational changes on safety and labor efficiency, including the reduction of nonessential field visits and the prevention of potential ESP failures. 
Results from the study demonstrate a substantial improvement in ESP performance and a marked reduction in environmental impact. The adoption of high-performance ESPs and digital operations led to a mean time to failure of 248 days, a significant increase in average run life from 110 days (with standard ESPs) to over 204 days, and ESP uptime consistently exceeding 90%. Real-time surveillance and remote interventions played a critical role in achieving these outcomes by enabling early identification of critical events and minimizing downtime. The adoption of advanced ESP technology and digital operations led to a substantial reduction in carbon footprint by 5% per well per year (approximately 202 tCO2e), achieved through reduced field trips, fewer workovers, and remote interventions that saved over 11,000 km (over 6,800 miles) in driving, reducing emissions by about 6 t CO2e. Three critical remote interventions prevented ESP failures, eliminating additional workover jobs and further reducing emissions by 1 t CO2e, for a total reduction of 7 t CO2e. 
This case study offers novel, real-world data on the environmental and operational benefits of enhancing ESP survivability and leveraging digital solutions, an area not previously addressed in the existing literature. By minimizing production loss and nonessential field trips, the operator not only improved operational efficiency but also made a positive impact on the environment. The findings provide actionable insights for practicing engineers seeking to improve both operational and environmental performance in oilfield operations. This work demonstrates that the strategic deployment of advanced ESP technology, combined with digital optimization and proactive remote management, can serve as a model for sustainable practices in the oil and gas industry.
