Presently my research focuses on the matching of models to various classes of reservoir responses. These "inverse problems" seek the values of unknown reservoir parameters by inference rather than direct measurement. Typical problems are: tracer analysis of fractures, computer-aided well test analysis, production schedule optimization, and automated history matching/decline analysis. In addition to this general class of problem, I have specific interest in geothermal reservoir engineering, and the multiphase flow of boiling fluids through porous materials and fractures.
I teach the undergraduate class, Fundamentals of Petroleum Engineering, as well as the graduate classes, Geothermal Reservoir Engineering, Well Test Analysis, and Optimization.
