Petrophysics and Surface Chemistry

Dr. Jill S. Buckley

Group Head

Dr. Guoyin Zhang acquired both his MS and PhD in Petroleum Engineering at the New Mexico Institute of Mining and Technology (NMIMT). Most of his research focuses on surfactant screening and modification. His specialty is in EOR surfactant development and formulation. Before his career at PRRC, he worked for Daqing Oil Company (Petro China) for over ten years, where, as the section head of Surfactant Development and Evaluation, he participated in the world's largest ASP flooding project in Daqing Oilfield, Heilongjiang, China. Dr. Guoyin Zhang has published nearly twenty technical papers.
