A Message from the President

I became President & CEO of Ultimate EOR Services (UEOR) on September 1, 2014. After 27 years working as a researcher in petroleum engineering with the University of Texas at Austin, I am very pleased to be starting the last phase of my career in this exciting and challenging role with Ultimate EOR.

UEOR’s mission is to provide economically viable Chemical Enhanced Oil Recovery (CEOR) solutions to increase oil production from all types of reservoirs.

The uniqueness of our company is:
- We have the most experienced and competent technical workforce in chemical EOR worldwide ,
- Our founders are world leaders in EOR technology, design and implementation,
- Our strategic partners and investors give us worldwide access to all aspects of EOR implementation
- We have patented superior technologies which can cost-effectively recovery oil in challenging conditions

With our recent facility expansion, we have over 7000 ft2 of laboratory space furnished with state-of-the-art equipment including several high-pressure live oil phase behavior and coreflood test modules. In addition to my core values of integrity and dedication to my work, I am committed to developing the UEOR team to their full potential while maintaining a safe environment.

Globally renowned founders

Dr. Gary A. Pope

Dr. Pope holds the Texaco Centennial Chair in Petroleum Engineering at UT Austin, where he has taught since 1977. Pope earned his Ph.D. from Rice University and a B.S. from Oklahoma State University, both in Chemical Engineering. His research is focused on enhanced oil recovery, reservoir engineering, natural gas engineering, reservoir simulation, characterization of reservoirs and aquifers with tracers, surfactants and water-soluble polymers, phase behavior and fluid properties, and groundwater modeling and remediation. In 1999 Pope was elected to the National Academy of Engineering.

Dr. Upali P. Weerasooriya

Dr. Weerasooriya is the Director of Surfactant Development within the CPGE at UT Austin. He earned his PhD from The University of Texas, MS from Bowling Green State University, and BSc from the University of Sri Lanka, all in Chemistry. Weerasooriya had over 27 years of surfactant industry experience before he joined the CPGE in 2008. His accolades include the prestigious Rosen Award (1999, Best Scientist) and the SDA (1998, Best Publication). He has been issued 13 U.S. patents and has commercialized several new surfactant processes. Weerasooriya’s research interests are in design, evaluation, and synthesis of new surfactants.

Dr. Mojdeh Delshad

Mojdeh Delshad is a research professor in the Department of Petroleum and Geosystems Engineering at the University of Texas at Austin. She holds BS degree in Chemical Engineering from Sharif University in Iran and MS and Ph.D. degrees in Petroleum Engineering from The University of Texas at Austin. She has over 30 years of experience in modeling multiphase flow, property modeling, and reservoir simulation of enhanced oil recovery processes. She has published 60 journal and 88 proceedings papers. She is in charge of the University of Texas Chemical Flooding Simulator (UTCHEM) development, user support, and training.
She has served as an associate editor for the SPE Reservoir Evaluation and Engineering Journal. She was awarded the SPE rank of “A Peer Apart” for reviewing more than 100 technical papers. She is the director and instructor for Chemical Enhanced Oil Recovery courses offered by Petroskills and SPE. She has served in the SPE books Development Committee. She received the SPE distinguished member Award in 2014.

Dr. Kishore K. Mohanty

Dr. Mohanty is a Professor of Petroleum Engineering at UT Austin. His research focuses on transport of simple and complex fluids in complex microstructured materials for applications in energy, environment and biotechnology. Many naturally occurring materials such as sandstones, carbonates, aquifers, human bones and tissues are microstructured. Many fluids in these systems are nanostructured. Mohanty’s research aims to image these structures, understand the physics of transport, relate the microstructures to transport coefficients and develop new materials for enhanced targeted transport.

Dr. Larry W. Lake

Dr. Lake is a Professor of Petroleum Engineering at UT Austin, where he currently holds the W.A. Moncrief Centennial Chair in Engineering. He earned B.S.E and Ph.D. degrees in Chemical Engineering from Arizona State University and Rice University, respectively. Lake is the author or co-author of more than 100 technical papers, four textbooks and the editor of three bound volumes. He has served on the Board of Directors for the Society of Petroleum Engineers (SPE), as well as on several of its committees. Lake’s numerous accolades include membership in the National Academy of Engineers, where he was inducted in 1997.
