Peter Eichhubl's research combines the fields of fault and fracture mechanics and low-temperature geochemistry addressing deformation mechanisms of the upper crust, structural control of mass and heat transfer in sedimentary basins, effects of chemical mass transfer on the mechanical and hydraulic behavior of fractures and faults, and the chemical interaction between fluids and minerals. Dr. Eichhubl's research is of applied interest to groundwater management and the exploration and production of hydrocarbons. Fundamental aspects of the research have implications for the seismic and aseismic deformation of the Earth's upper crust and for the interaction of subsurface fluids with the atmosphere and biosphere.

Christopher Landry
My research interests revolve around prediction of fluid migration in porous and fractured porous media, including the study of non-continuum, multiphase, and reactionary flows with a focus on pore-scale processes. My expertise is in the application of image-based analysis and employment/development of pore-scale flow models to predict fluid transport properties of heterogeneous geomedia and elucidate coupled flow processes, as well as the development of methods to upscale these results to intermediate and field scales. I am generally interested in research involving fluid flow in geomedia, including, but not limited to, hydrocarbon recovery, CO2 sequestration, contaminant transport, and water resources management.

Zhiqiang Fan
I joined BEG as a postdoctoral fellow in 2013 after getting my Ph.D. in mechanical engineering from University of Maine. With a solid background of mechanics, I enjoy multidisciplinary research and have a wide range of research experiences. For my master theses, I analyzed the large deformation and instability of hyperleastic materials. For my Ph. D, I developed computational/analytical models to simulate natural hydraulic fracture initiation and propagation associated with transformation of solid kerogen to liquid oil, and conversion of oil to gas in shale formations. I also investigated multiple hydraulic fractures in poroelastic rocks. My current research is focused on fluid injection induced earthquakes. We try to investigate the causative relationship between fluid injection and induced seismic fault slip by integrating geological and geophysical data into a poroelastic finite element model. My research interests include borehole stability, hydraulic fracture, interaction between fluid flow, rock deformation and crack growth, and abnormal pressure modeling in sedimentary basins.

Xiaofeng Chen
Starting in April 2015, I joined the FRAC group at BEG after earning my PhD in Geology at the University of Oklahoma. My research focuses on the understanding the mechanical properties of rocks under seismic and reservoir related conditions using laboratory experiments along with nano-scale analysis. My PhD work was to investigate the rock frictional properties under seismic velocities. Combined with high-resolution characterization, I discovered several effective dynamic faulting mechanisms such as dynamic smoothing, powder rolling, and frictional melting which broadened the understanding of earthquake physics. My current research project is to experimentally study the geomechanics of CO2 reservoir rocks. We plan to explore the effect of reservoir environmental factors associated with CO2 injection such as fluid with different chemical composition, temperature and pressure on reservoir rock mechanical especially the seal properties by fracture mechanics tests, rock mechanics tests and nano-scale characterization.

Graduate Students

Owen A Callahan , Ph.D., expected 2018 (Supervisor)
I investigate fluid flow in faults and fractures, specifically the interplay between hydrothermal alteration, mechanical deformation, and conduit evolution in high temperature hydrothermal systems, using field observation, petrographic characterization, and experimental rock mechanics.

Jonathan Major , Ph.D., expected 2017 (Supervisor)
I consider myself primarily an applied structural geologist and tectonicist, but I have a wide range of interests and research experiences. In the Jackson School I work with the FRAC group at the Bureau of Economic Geology. My current research is focused on understanding the interactions between structures, fracturing, and geochemistry, primarily focusing on fracture systems found in mudrocks. More specifically, my dissertation is assessing fault and top seal behavior in CO2-rich systems by looking at an natural analog near Green River, Utah. I am combining field work, experimental geomechanics, petrography, petrology, and numerical modeling to do this. The primary application of my work is long-term carbon sequestration, but it also has relevance to CO2-injection for enhanced oil recovery (EOR) and mudrock fracture systems in general. My primary field research areas are the Colorado Plateau in Utah, and eastern Indonesia where I conducted my MS thesis.

Casey M Obrien , M.S., expected 2016 (Supervisor)
Hi! I am a masters student conducting research in the Fracture Research and Application Consortium. My work involves studying coupled mechanical and chemical diagenetic processes in deformation bands in sandstone. In particular, I am interested in identifying how these mechanical and chemical processes affect fluid flow properties in the bands. I employ scanning electron microscopy (SEM) imaging techniques to study microscale textural properties such as pore geometry and connectivity, grain size and mineralogy, degree and type of cementation within bands. In addition to microscale textural studies, I have conducted field work in the area of the San Rafael Swell, Utah, so that microscale textural observations can be integrated with field observations and placed into an outcrop- and reservoir-scale framework.

Erick Wright , M.S., expected 2016 (Supervisor)
My interests are in structural geology and the coupled mechanical and geochemical processes of fracture, fluid flow and diagenesis. My current masterís thesis project seeks a better understanding of permeability within fracture cements of low permeability rocks. I employ argon ion milling and SEM imaging techniques on fracture cements in core and outcrop samples from a variety of low permeable formations. Through this work, I intend to gain a better understanding of the mechanical and/or chemical processes that may preserve or destroy potentially conductive, nanometer scale open pores in fracture cements which may act as flow channels along and across fully cemented fractures and aid in production when intersected by hydraulic fractures.

Natchanan Doungkaew (Supervisor)
I study processes of fracture growth in quartzitic sandstone of the Campito Formation, eastern California, by combining field structural observations, thin section petrography, and fluid inclusion microthermometry. Since processes of fracture formation control flow of fluid in the subsurface and the mechanical properties of the brittle crust, understanding of fundamental fracture growth mechanisms is essential for understanding fracture formation and cementation in chemically reactive systems with implications for seismic and aseismic fault and fracture processes, migration of hydrocarbons, long-term CO2 storage, and geothermal energy production.

Johnathon Osmond (Committee Member)
I conduct structural interpretation and analysis using outcrop, seismic, and well data to better understand the structural architecture of Texas basins for seismicity research. Research Interests: - Crustal deformation, particularly brittle processes - Geometry of structural hydrocarbon traps and the sealing capability faults - Geophysical techniques in support of structure, tectonic, and petroleum studies - Geologic field methods and geophysical data acquisition

Fault and fracture processes, structural diagenesis (Graduate)
Graduate student projects combine the fields of fault and fracture mechanics and low-temperature geochemistry addressing deformation mechanisms of the upper crust, structural control of mass and heat transfer in sedimentary basins, the effects of chemical mass transfer on the mechanical and hydraulic behavior of fractures and faults, and the chemical interaction between fluids and minerals. Projects usually require the integration of field and laboratory analytical or numerical work and preference goes to applicants that are equally comfortable in the field and in the lab. Research topics include field- and core-based structural geology, geomechanics, geofluids, geochemistry, and natural resources including CO2 sequestration. A current research emphasis lies in Structural Diagenesis which combines the traditionally separate fields of brittle structural geology and diagenesis/geochemistry. Preference goes to PhD applicants with a prior MS degree and MS applicants with undergraduate research experience, preferentially through completion of a senior's thesis. Applications should be submitted to the MS or PhD program in Geological Sciences (GEO). Please contact Peter Eichhubl ( for further details.
