Dr. Flemings' research couples observation with theoretical analysis to study crustal fluid flow at human and geologic timescales. He asks classical questions such as: 1) what is the relationship between faulting, pressure, and stress? 2) what is the shallow crust's permeability and how does it vary with pore pressure? 3) how is continental margin morphology controlled by fluid flow? 4) how do hydrocarbons move at both geological and production time scales?

Postdocs

Kehua You
Kehua joined UT Geofluids as a postdoctoral fellow in June 2013. She earned her Ph.D. in geology from Texas A&M University in 2013, and her B.S. in environmental sciences from University of Science and Technology of China in 2008. She specializes in theoretical and computational hydrogeology, contaminant hydrology and reservoir simulation. Her primary research interest lies in fluid flow and transport in subsurface environment.

Athma R Bhandari
I work for the UT Geofluids Consortium at the Bureau of Economic Geology. I earned my Ph.D. (Geomechanics and Geotechnical Engineering) from University of Southampton, M. Eng degree in Civil Engineering (Applied and Rock Mechanics) from the University of Tokyo, and B. E. degree in Civil Engineering from Tribhuvan University, Nepal. My main research interests lie in experimental geomechanics, more specifically, laboratory study of deformation and flow in geomaterials (soils and rocks). I examine the underlying mechanics of observed macro-scale behavior of geomaterials. In my current research, I measure shale permeability under reservoir pore and confining pressure conditions. It aim to predict porosity and permeability behavior in shales through the production life cycle.

Graduate Students

Dylan W Meyer, Ph.D., expected 2017 (Supervisor)
My research is centered around methane hydrate stability and gas migration mechanisms in submarine sediments on continental slopes around the world. I have been working on determine the thermodynamic phase state of the hydrates within these sediments to gain understanding into the formation of these hydrate-systems as well as the sensitivity of these systems to fluctuating in situ conditions. This research is important for three reasons: a) Methane hydrates are an important potential energy resource for countries all around the world. b) Global climate change could potentially dissociate much of these hydrate systems, releasing massive amounts of methane gas into the atmosphere and compounding the affects of global warming. c) The release of free gas into the near-subsurface could increase to frequency and severity of submarine landslides.

Jason C Sanford, M.S., expected 2014 (Supervisor)
Jason is an M.S. Candidate in Geological Sciences at the University of Texas at Austin, where he is currently exploring geopressure history and geomechanics of reservoir-scale sand injections in the Panoche Giant Injection Complex in central California as the second component of his M.S. thesis work. Efforts include mapping of sand injections in the PGIC in order to construct 3-D physical and 2-D geomechanical models of sand injection and understanding and modeling hydraulic fracture initiation and propagation and fluid-sand slurry transport during sand injection. As the first component of his M.S. thesis work, Jason mapped the Cretaceous-Paleogene boundary deposit in the Gulf of Mexico, employing regional seismic, well-log, and core interpretation in order to evaluate the basin's response to the Chicxulub Impact.

Michael B Cronin, M.S., expected 2013 (Supervisor)

Baiyuan Gao, M.S., expected 2013 (Supervisor)
Baiyuan is currently working on pore pressure prediction within dipping reservoirs. She will systematically study the effects of reservoir relief, mudstone properties, and 3D geometry on reservoir pressure. She will also develop simple approaches to predict the in-situ reservoir pressure.

Graduate and Post-Doctoral opportunities in GeoFluids Research Group (Graduate)
The GeoFluids Research Group has immediate opportunities for graduate and post-doctoral study. Dr. Flemings is most enthused by students who have a commitment to a doctoral program because that allows time to delve deeply into research. However, he also regularly accepts exceptional M.S. students into our research group. If you are interested, please e-mail, Peter Flemings (pflemings@jsg.utexas.edu).

Current Research Opportunities:

1. Hydrate Melting:
Examine the melting of methane hydrates in Arctic systems. DOE funded effort will examine the impact of warming over human time scales and longer. The project description is found here. We are looking for students and post-doctoral scientists with a fascination for marine geology and a yen for quantitative analysis of fluid flow.

2. Mass Transport in Shales:
Study transport processes in shale systems! You will perform permeability testing of shales (e.g. the Barnett, the Marcellus…) and develop multi-scale numerical models to describe mass transport within these systems. The work will include both laboratory analysis and sample characterization. This project is supported by Shell.

3. GeoPressure Analysis:
Study geopressure in sedimentary basins through our industry funded consortium UTGeoFluids. Dr. Flemings is always looking for students with a yen to characterize and model overpressure in sedimentary basins.

4. Mudrock Geomechanics:
Study the geomechanics of mudrocks through experimental analysis. This research is supported by UTGeoFluids. In this research, we analyze both intact samples (from industry and the ocean drilling program) and we synthetically create mudrocks. We ask fundamental questions such as:
How to mudrocks compact?
What is the permeability of mudrocks and how does it evolve?
What is the strength of mudrocks?
