Executive Summary
Over the past two decades, seismic attributes have become crucial for mapping structure, stratigraphy, and quantifying reservoir properties. Our research group focuses on refining poststack and prestack data, calibrating attributes to geological and engineering standards, and utilizing advanced analysis techniques for unconventional reservoirs. We leverage comprehensive datasets including 3D surveys, production data, well logs, and more.
Our goal is to improve the accuracy of reservoir characterization and hydrocarbon estimation by addressing acquisition, processing, and imaging impacts on seismic attributes. We provide research reports and algorithm source code to sponsors for internal use and client services
Research Themes
When well-log and production data are properly aligned, broadband 3D seismic data becomes pivotal in delineating reservoir heterogeneity and compartmentalization. We've found that modern seismic attributes greatly enhance our ability to visualize stratigraphic and tectonic features, even surpassing classical seismic resolution limits. Notably, attribute images computed on limited offset and azimuth volumes from North and West Texas exhibit higher lateral resolution. Additionally, we've observed variations in feature illumination with offset and azimuth, particularly in land surveys rich in azimuths.
Our research focuses on four main goals: mapping reservoir compartments and fractures, optimizing seismic processing workflows for improved resolution, contextualizing seismic attributes with tectonic deformation and geomorphology, and developing predictive tools for guiding reservoir completion programs.

The RCML is directed by Matt Pranter. Dr. Pranter and his students investigate the controls that stratigraphy, sedimentology, and structure play in regard to reservoir architecture, lithological and petrophysical-property heterogeneity, and reservoir performance. A fundamental goal is to assess the dominant controls on reservoir quality (both matrix and fracture) to more accurately map and model the spatial distribution of reservoir properties.
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.
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.
