PRRC, New Mexico Technology and Mines Institute, USA;Dr. Randy Seright has developed polymer flooding and gels to improve sweep efficiency in reservoirs since 1978, when he started his career with Exxon. He worked at New Mexico Tech for 36.5 years, helping to make polymer flooding and gel treatments more viable. Seright has been involved in many major polymer flooding projects throughout the world, including projects in China, Canada, India, Argentina, Suriname, Kazakhstan, and Alaska (USA). He has provided short courses on Polymer Flooding and Water Shutoff in 19 countries. He received the SPE/DOE IOR Pioneer award in 2008 for his work using polymer and gels to improve oil recovery. He holds a B.S. degree in Chemical Engineering from Montana State University (Bozeman) and a Ph.D. degree in Chemical Engineering from the University of Wisconsin (Madison).

EPPOK, France;Antoine Thomas is an independent consultant specializing in enhanced chemical oil recovery (EOR) & conformance. He holds an MSc in Geology, Reservoir, and Petroleum Engineering from ENSG in Nancy, France. Over the past 15 years, Thomas has led the design, implementation, and monitoring of chemical EOR projects across Russia, Argentina, Canada, Kazakhstan, India, and Europe, with particular expertise in polymer flooding, conformance control, and water shut off. He is the author of Essentials of Polymer Flooding Technique (Wiley, 2019) and has published proceedings widely in SPE and EAGE. He regularly teaches training courses on chemical EOR and conformance management and advises companies on EOR strategy. More information is available at polymer-flooding.com.

Petroleum Engineering Department of KFUPM, Saudi Arabia;Dr. Madhar is working as an assistant professor in the Petroleum Engineering Department of KFUPM. He is a recognized expert in reservoir engineering and rheological aspects of polymer EOR and has published several related papers in SPE, including a critical review paper (SPE 195687-PA) and a screening criteria paper (SPE 223155-PA) that resolved a decade-long debate within the polymer EOR community. He is serving as an Associate Editor for SPE and has won several technical awards: a) the 2025 SPE Regional Reservoir Description and Dynamics Award, b) the 2025 SPE Outstanding Associate Editor Award, and c) the SPE Outstanding TE Award (four times) (2021, 2023, 2024, 2025). He holds a PhD, an MS, and a B.Tech in Petroleum Engineering from the University of Alberta, Edmonton, Canada; King Fahd University of Petroleum & Minerals, Dhahran, Saudi Arabia; and Rajiv Gandhi College of Engineering, Anna University, Chennai, India.
