Optimization and reservoir Simulation.

My research is focused on reducing the risks of climate change by developing energy supplies with low carbon emissions. Students and post-doctoral fellows in my research group work on carbon dioxide storage, energy systems analysis, and pathways for transitioning to a low-carbon energy system.

Efficient nonlinear solvers for the simulation of multiphase flow in porous media

Currently, my research focuses on the enhanced oil recovery using nano-particles and multiphase flow in porous media.

membranes; Characterization of well-core & heavy oil; CO2 separation & sequestration process; Enhanced oil recovery method for offshore oil field; fuel cells system & hydrogen production.

I'm working on linear solver framework in Stanford's reservoir simulator (AD-GPRS). More broadly, I'm interested in efficient solution/preconditioning strategies and parallel algorithms in subsurface flow modeling.

Addressing the Propogation of Seismic Image Uncertainty Through the Reservoir Forecasting Process.

- Fusion of reservoir simulation and history matching
- Development of high-performance geostatistical algorithms

My students and I use theoretical, computational, and statistical models, to discover and understand fundamental relations between geophysical data and subsurface properties, to quantify uncertainty in our geomodels, and to address value of information for decision making under uncertainty.

My research focuses on understanding physical mechanisms that cause injection-triggered seismicity. I am designing engineering strategies to mitigate triggered seismicity by leveraging knowledge of the coupled processes of subsurface fluid flow, geomechanics, and earthquake dynamics.

I am also interested in petroleum and geothermal reservoir geomechanics, especially as applied to reservoir stimulation technologies.

I am interested in applying the new developed techniques for Temperature Transient and Pressure Transient Analysis, to determine key flow parameters such as permeability, in a Naturally Fractured Reservoir. The main advantage of using the Temperature response, is it's characteristic of being an advection-diffusion problem, so the Temperature response carries more information than the Pressure response.

My current research focused on the experimental study of transient, unstable immiscible flow in micromodels.

I am interested on investigating the effects of geological uncertainty on reservoir responses on both production and seismic responses. the geological uncertainty specifically investigating are uncertainty on how the structure has been deformed, and how the mode of rock accommodation on given deformation. Geomodels created from properly chosen set of geological scenario may give a better understand on how the reservoir may behave.

My research interests involve developing and using microfluidic platforms to visualize pore-scale flow phenomena relevant to reservoir engineering. Secondary and tertiary recovery can cause clay particles to detach from the rock matrix and block subsequent pore space, significantly reducing reservoir permeability. Currently, I am conducting experiments to visualize the impact of brine composition and salt concentration on the release of clay particles from the rock matrix.
