Our Team

Stephanie is a senior engineer, laboratory supervisor, and safety officer specializing in formulation design and chemical structures. She received her PhD in chemical Engineering and has over 10 years' experience working with surfactants for emulsions, foams, and microemulsions. Stephanie is mainly responsible for assisting with the development, optimization, and comparison testing of chemical formulations for a wide variety of reservoir and injection conditions.

Chris is a senior scientist and laboratory supervisor at UEORS. He is responsible for managing laboratory work including chemical EOR design, experimental execution and experimental capability development. He specializes in challenging EOR environments, including high temperature and high salinity.

Jonathan joined UEORS in 2017 and specializes in EOR polymer projects. He holds a B.S. in chemistry from Rice University, an M.S. in petroleum engineering from the University of Texas, and a Ph.D. from Rice University in bioengineering. He provides in-house expertise on polymer selection, characterization, and evaluation.

Mina is a reservoir engineer with more than 10 years of experience in conventional oil reservoirs and unconventional shale plays in the United States and the Middle East. She has several publications on innovative methods for reservoir characterization to greatly improve the accuracy of permeability estimates, capillary pressures and relative permeability curves.

Dan is a Petroleum Engineer at UEORS who specializes in polymer evaluation, EOR design, and high pressure coreflood experiments. His other experience includes chemical EOR pilot implementation and chemical quality control. His interests are heavy oil recovery, field scale application of EOR, and challenging EOR environments.

Gayani works as the Office Manager for Ultimate EOR Services. She is responsible for accounting, administration and hospitality. She has 4 years of experience in technical chemical EOR research at UT Austin. Her special research interest is surfactant development and synthesis.

Eric is a laboratory engineer at UEORS responsible for EOR design and coreflood experiments. He is the in-house specialist for high pressure, live oil experimentation, including phase behavior and corefloods. Prior to his position at Ultimate EOR, Eric worked as a laboratory research assistant in Dr. Pope's EOR group at the University of Texas for over two years.

Nadeeka joined UEORS in March 2019 as the surfactant specialist designing surfactant formulations for challenging reservoir conditions. Her emphasis is on the development of Chemical EOR methods of alkaline Surfactant Polymer (ASP), SP and ACP (Alkaline/Co-Solvent-polymer). She holds a Ph.D. in photochemistry with more than 8 years of experience in surfactant formulations, polymer evaluation, surfactant quality control, and EOR methods for heavy oil. She also specializes in chemical synthesis, characterization, developing analytical methods for EOR chemicals, and evaluating rheological properties of complex EOR fluids.

Winoto is an engineer responsible for designing low salinity and wettability alteration experiments. He has B.Eng. and Ph.D. degrees in chemical engineering from University of Surabaya and University of Wyoming, respectively. He spent 5 years working as a research scientist for Professor Norman Morrow. His interests include polymer-supercritical fluid systems phase equilibrium, interfacial phenomena, wettability and special core analysis in oil recovery.
