Research Interests
My research interests are centered around the prediction of rock properties required for engineering calculations, using geological models and concepts. Rock properties I am interested in include porosity, permeability, pore size distribution and capillary effects, cation exchange capacity, wettability and mechanical properties. Successfully understanding the relationship of these geologic processes and the resultant rock properties can allow prediction of these properties in 3 dimensions. Engineering applications include modeling of fluid flow through reservoir simulation, interpretation of fluid saturations and other properties from well logs, predicting changes of porosity and permeability from compaction induced by fluid withdrawals, and understanding the propogation of natural and hydraulic fractures.
