Enhanced Oil Recovery (EOR)—including chemical, CO₂/gas, and thermal methods—plays a vital role in maximizing output from mature wells and fields. As a continuously evolving discipline, EOR presents both opportunities and challenges. This session is dedicated to exploring best practices, emerging innovations, and key obstacles in the effective implementation of EOR technologies.

Presentations:

   Zachary Broussard, Hunting Intl
• What’s Really Happening in South America’s Mature Oilfields?
  Aylén Giuliana De Vita, SNF Argentina SRL 

Chairs: Victor Duarte, Baker Hughes; Cristian Ivan Von Zedtwitz, Halliburton

This session covers the integration of traditional well performance analysis with advanced digital transformation and Industry 4.0 technologies tailored for mature onshore oil and gas fields. It emphasizes understanding historical well performance for accurate diagnosis and effective interventions aimed at increasing hydrocarbon rates, reducing decline rates or water production, and enhancing overall well productivity. Key topics include zonal contributions, pump parameters, choke sizes, and the use of digital tools to determine what, how, and when to measure for optimized well performance, ultimately supporting improved recovery factors and operational efficiency in mature fields. 

Presentations:

• Smart ESP Operations: Machine Learning-Driven Estimation of Downhole Gauge Parameters in Real-Time
  Jainish Darshak Shah, Juan Pablo Atencia, Frank Corredor, Halliburton

• Reservoir Surveillance of Mature Onshore Fields
  Marco Thiele, Streamsim Technologies

• Unlocking Bypassed Zones: Saturation Log Applicatons in Pilar Field
  Ivana Mijahuanca, Origem Energia

Chairs: Homayra Tavares, Petroreconcavo; Luis Quintero, Oilfield Development Specialists (ODS)

Well Integrity (WI) during the well life focuses on the continued good health of the well to ensure continued production/injection while at the same time mitigating risks of uncontrolled flow of formation fluids to the surface or to other sub-surface permeable zones. From the regulatory point of view, WI is also an essential requirement in the operation of the well, and especially critical for plug and abandonment.
 Wells with WI issues may require immediate attention, with accurate and reliable diagnosis and follow-up remediation as they may lead to catastrophic risks, and/or delayed or stopped production. Well Integrity, barriers, and monitoring and/or evaluations are expected to be discussed in this session.
