Dr. Mohanty's research focuses on transport of simple and complex fluids in complex microstructured materials for applications in energy, environment and biotechnology. Many naturally occurring materials such as sandstones, carbonates, aquifers, human bones and tissues are microstructured. Many fluids used in these systems are nanostructured. This research is aimed at imaging these structures, understanding the physics of transport, relating the microstructures to transport coefficients and developing new materials for enhanced targeted transport.

Prof. DiCarlo's research interests include using advanced experimental techniques such as multi-energy CT scanning, synchrotron radiation, and acoustical measurements.

Prof. Huh's research interests include process modeling for various enhanced oil recovery processes, such as surfactant/microemulsion flooding, polymer flooding, miscible and near-miscible gas injection processes, use of foam to improve effectiveness of chemical and gas injection processes, and heavy oil recovery from unconsolidated sands. Having previously worked in a major oil industry research laboratory tackling various oil recovery problems, Prof. Huh's main focus has been improvement of the EOR model features that require modification from actual field application of those processes, and the adaptation of those improvements for reservoir simulators for improved field performance.

Dr. McClure's research is focused on modeling and characterization in three complementary areas: hydraulic stimulation of shale gas reservoirs, hydraulic stimulation of geothermal reservoirs, and induced seismicity. He develops unique modeling tools designed to better describe the physical processes taking place during these complex processes. Objectives: to develop better physical understanding of fundamental processes, to develop improved modeling techniques and tools, to develop improved methodologies for determining induced seismicity hazard, and to develop practical techniques that could be used in the field to improve economic performance and mitigate risk.

Dr. Quoc Nguyen's recent research has focused on the interface between colloid science and the engineering of complex fluids, such as foam, nanoparticle dispersion, emulsion, surfactant and polymeric solutions. His parallel program of modeling and experimentation has been aimed at understanding subsurface transport phenomena (including dynamics of colloids and complex fluids in porous media, reactive flow, and heat transfer), and developing optimum control methods for subsurface processes. His research has applications in enhanced oil recovery (EOR), conformance control technology, hydrocarbon production stimulation, in-situ thermal and chemical conversion of tar sand and oil shale, and nano-sensing. In previous research in the downstream petroleum industry, he led several projects on oil refining (distillation and extraction) and petrochemical (cracking and reforming) processes. In the environmental area, Nguyen was involved in numerous industrial research projects on hazardous waste treatment and the development of clean production technologies. His current research projects are in the areas of chemical and gas flooding for EOR; conformance control with complex fluids; production stimulation of unconventional resources; thermal and chemical conversion of tar sand and oil shale; engineering of nanoparticles.

Dr. Pope's research interests include enhanced oil recovery, the use of tracers for reservoir characterization and numerical reservoir simulation. His research on enhanced oil recovery over the past 32 years has included work on chemical flooding, polymer flooding, miscible flooding, steam flooding and in-situ combustion. The emphasis in this research is on the experimental investigation of how phase behavior, fluid properties and rock/fluid interactions affect these enhanced oil recovery processes and how to model these phenomena as well as how to use simulators to optimize, scale up and predict performance. Current research includes the development of a next generation chemical flooding simulator, the use of partitioning tracers for integrated reservoir characterization, the remediation of gas-condensate wells to improve productivity, three-phase relative permeability models, and the development of high-performance surfactants for enhanced oil recovery.

Dr. Wheeler's major research interests are the formulations and analysis of parallel algorithms for modeling multiphase, multicomponent flow and transport in porous media, including derivation of a posteriori error estimators. Under her direction, the Center for Subsurface Modeling at UT has developed the IPARS (Integrated Parallel Accurate Reservior Simulator) framework. This software has been extensively tested and has been shown to be comparable to existing industrial simulators. IPARS currently contains the following models: sequential and implicit (oil-water) two-phase; implicit black-oil (three phase, three component); two phase (air-water) implicit; explicit and implicit single phase; equation of state compositional; black-oil coupled to geomechanics and reactive transport coupled to multiphase flow models. An attractive feature of IPARS is that it allows for the coupling of different models in different subdomains and supports message passing parallel computations on structured multi-block meshes in two and three spatial dimensions.
