Rock Deformation and Experimental Earthquake Physics Facilities

The School of Geosciences has laboratories that are dedicated to:

• determinations of earthquake physics (fault behavior) at conditions relevant for earthquake nucleation and propagation
• the creation of fractures and determination of their mechanical parameters
• the characterization of deformation and measurement of rock properties at shallow crustal conditions

Experimental Earthquake Physics and Geotribology Lab:

This  laboratory has three different experimental platforms:

            -Rotary Shear Apparatus-

Experiments can be performed on solid rock specimens at loading rates consistent with earthquake nucleation and propagation. Further, at slow velocities, off-fault strain and radiated energy can be measured and analyzed, i.e., the ability to record a laboratory earthquake in the near-field at high rates. Additionally, this apparatus can run experiments on powdered gouge under dry and saturated conditions. In total this apparatus offers the ability to characterize the strength and slip behavior of different geologic materials as it relates to fault slip and earthquake physics.

             -Fracture Mechanics Apparatus-

The testing apparatus has the ability to acquire fracture mechanical parameters from rock samples, including fracture toughness, subcritical fracture growth index, and the curves of stress intensity factor vs fracture velocity under saturated conditions (where fluid chemistry can be an experimental variable). Such measurements have direct application to operations that create fractures in the subsurface.

            -Bruker Tribometer System and Profilometer-

This system, originally designed for engineering purposes, is used to test the friction/wear/hardness of geomaterials over a range of velocities and at various conditions. The capabilities of the platform allow for experiments that target such topics as fault mechanics, friction and wear along bimaterial faults, the evaluation of friction laws at high temperatures, and the mechanics of glacial sliding and silt production.

Experimental Rock Deformation and Poromechanics Lab [formerly the integrated PoroMechanics Institute (iPMI)]:

The equipment in this lab offers an integrated approach to researchers of various disciplines including petroleum engineering, geology, geophysics, civil engineering, computer science, and electrical engineering to conduct general and applied research on the mechanics of porous materials, in particular, geomechanics applied to hydrocarbon exploration/production, geothermal energy production, and carbon dioxide sequestration.

Structural Geology Laboratory

The digital workroom includes two dual monitor Dell PC workstations, a Sun Blade workstation, and a SGI Octane workstation. The PCs are primarily used for GIS applications, Cross section construction and 3-D modeling. The Sun Blade and SGI workstations are primarily used for seismic interpretation (Landmark and Geoquest) and 3-D visualization.

The physical modeling laboratory is equipped with controlled hydraulic and electric displacement equipment. These are employed to exert a variety of displacement boundary conditions on models made of sand, clay or plaster. Most of the experiments done in this laboratory are directed toward studies of upper crustal deformation, primarily faulting and fracturing.

Thin Section Petrography Laboratory

This laboratory contains research quality microscopes for graduate and undergraduate students, as well as faculty and researchers, to conduct petrographic research. It contains two Zeiss microscopes, including a Zeiss Imager Z1 which is capable of taking thin section photomicrographs. The lab also includes a Nikon reflecting light microscope and a Nikon binocular microscope.

Attribute Assisted Processing & Interpretation (AASPI)

During the past two decades, seismic attributes have become a key component not only in mapping structure and stratigraphy but also in a quantitative reservoir characterization. In addition to enhancing individual faults and discontinuities, geometric attributes help interpreters map axial planes for structural analysis, relate curvature to intensity and orientation of fractures, and map lateral changes in reflectivity to detect channels below seismic resolution. During the 2013 AASPI Consortium research program, we will continue our focus on poststack and prestack data conditioning, calibration of attributes to geological and engineering control, and the use of LMR and AVAz analysis of unconventional reservoirs. Our research is driven by the data provided by our sponsors, such that our primary efforts will be on the application of these attributes over resource plays and mature fields of North America (US, Canada, and Mexico) that have a combination of proprietary 3D surveys, production data, well logs, microseismic data, image logs, production logs, and core, within a well-understood geologic framework. We believe that a better understanding of the impact of acquisition, processing and imaging on seismic attributes is key to quantifying the errors in reservoir characterization and hydrocarbon estimation provided by modern attribute-driven geostatistics, neural networks, and clustering technology. In addition to research reports, we provide algorithm source code to all sponsors and attribute volumes to those sponsors who wish to provide us with 3D seismic data. More information can be found on the AASPI website.

The iPMI is directed by Dr. Younane Abousleiman and was established in 2002 with ties to the Larry W. Brummett/ONEOK Chair Professorship.  The integrated PoroMechanics Institute offers an integrated platform to researchers of various disciplines including petroleum engineering, geology, geophysics, civil engineering, computer science and electrical engineering to conduct general and applied research on the mechanics of porous media; in particular, geomechanics applied to exploration and production of hydrocarbons.

The Environmental Compound-Specific Isotope Analysis (CSIA) Laboratory evolved over the past two decades from the Organic Geochemistry Group in the School of Geosciences of the University of Oklahoma. The success in development of CSIA methods for analysis of environmental samples led to establishing an in-house research program focused on CSIA of environmental contaminants, and creation of an analytical service facility, serving academic and industrial customers since 2003. Today, the laboratory houses three GC/IRMS systems for determination of carbon and hydrogen isotope ratios. A GC/qMS system is used for determination of chlorine isotope ratios. The laboratory is equipped for handling of the complete suite of environmental samples (water, organic liquids, sediment and air). In addition, GC/qMS instrumentation permits characterization of organic composition of samples.

Quantitative Grain Size and Grain Shape Analysis

Grain size and texture are measured in the lab using the Malvern Mastersizer 3000 and the Malvern Morphologi G3. The Malvern Mastersizer 3000 uses laser diffraction to measure grain size distributions of sediment samples. Different modules allow the measurement of a wide range of sample sizes and grain sizes (sub micron to 2 mm). The Malvern Morphologi G3 quantitatively measures particle size and 2-D shape by photographing and analyzing each individual grain. Grain metrics and bulk geometrical statistics are calculated with the Malvern software.

The newly established Aqueous Geochemistry Laboratory provides analytical and sample processing support for research on organic matter in natural waters. Instrumentation in the AGL includes:
