Dr. Hazlett joined the faculty in Fall 2012 with more than 25 years of industry experience. He joined the R&D department at Mobil in 1986 after graduate studies at the University of Texas at Austin under the supervision of Professor Robert S. Schechter. Dr. Hazlett’s dissertation topic concerned measurement and theoretical modeling of macroemulsion stability in near critical microemulsion systems for low tension waterflooding. While at Mobil, Dr. Hazlett worked on a balance of cutting edge research involving high temperature, high pressure experimentation and theoretical process modeling. He worked alongside researchers at Brookhaven National Laboratory and Los Alamos National Laboratory developing methodology to simulate multiphase flow in pore-level, microtomographic renderings of reservoir rocks. He fostered cross-disciplinary research in analytic solutions to the Laplace Equation for application in reservoir simulator well equations. That work evolved into a concentrated effort on performance models appropriate for describing complex wells. Dr. Hazlett holds more than a dozen U.S. Patents.
