Mechanical Stratigraphy, Stress and Geomechanics
This course will apprise course participants of key concepts in mechanical stratigraphy, stress, and geomechanics. Participants will develop the skill sets necessary for planning and evaluating a stress analysis and geomechanics study.
Business Impact: We will explore the importance and application of stress and geomechanical analyses to energy exploration and production in both conventional and unconventional reservoirs, with emphasis on the importance of mechanical stratigraphy and stress states on processes such as natural deformation and hydraulic fracturing.
Schedule
Duration and Training Method
This is a classroom or virtual classroom course comprising a mixture of lectures, discussion, and computer-based exercises.
Course Overview
Learning Outcomes
Participants will learn to:
- Characterize mechanical stratigraphy based on lithostratigraphy and other information.
- Assess the role of mechanical stratigraphy and stress conditions on rock deformation behavior including fracture prediction in unconventional and conventional reservoirs.
- Assess the difference between shear and extension fractures and their different effects on permeability anisotropy.
- Evaluate the basics of stress analysis and geomechanics, including the interrelationship between stress and strain in the context of geomechanical rock behavior. Estimate an in situ stress field for an area of interest.
- Evaluate geomechanical issues for common petroleum and unconventional resource applications such as well design, borehole stability, and hydraulic fracturing.
- Plan and evaluate a geomechanics study.

Instructors
Adam Cawood
Background
Dr. Cawood is a structural geologist with research experience in extensional, strike-slip, and contractional tectonic regimes at a range of scales, and in various geological settings. He has expertise in field mapping, close-range remote sensing (LiDAR and digital photogrammetry), outcrop-based deformation analysis, core characterization, seismic interpretation, and basin-scale tectonostratigraphic analysis. Study areas have included sites across the U.S. (e.g., west Texas, the Permian Basin, the Rocky Mountains, Utah), offshore Newfoundland (Canada), Pembrokeshire (UK), the Zagros Mountains, and the French Alps.
Dr. Cawood has expertise in acquisition, processing and analysis of digital photogrammetry and LiDAR data. He has developed workflows to integrate remotely acquired datasets with field and laboratory data, established digital approaches to geological analysis, assessed the errors and uncertainties associated with remotely acquired data, and developed novel approaches to data extraction, handling and analysis. His research focuses on natural deformation processes, with an emphasis on leveraging structural data for improved understanding of the subsurface. Applications of his work include hydrocarbon exploration and production, geothermal energy extraction, subsurface storage and waste disposal, and groundwater management.

Kevin Smart
Background
Dr. Smart is a structural geologist with cross training in computational solid mechanics. His expertise is in the areas of structural geology and tectonophysics, nonlinear finite element analysis, field mapping, strain and microstructural analyses, and geologic fracture analysis. Dr. Smart’s research has ranged from outcrop and microscale analyses of carbonate and clastic rocks of the Appalachian, Ouachita, and Alpine contractional orogenic and the Basin and Range and Balcones Fault Zone extensional systems to field and laboratory studies of igneous and metamorphic rocks in the Wichita Mountains, Colorado Front Range, and southeastern Alaska.
Geomechanics efforts have included diverse applications in reservoir characterization (e.g., natural fracture prediction and production-related deformation, borehole stability, induced hydraulic fracturing), analyzing thermal effects on stress state evolution, and finite element analyses of ground response to seismic events. He has also conducted NASA-sponsored research to better understand the development of pit crater chains, landslides, and wrinkle ridges on Mars.
Dr. Smart is currently part of an integrated team that performs structural geology and geomechanics technical assistance and research projects for the oil and gas industry. His work in this area includes using geomechanical models to predict fracture distributions in conventional and unconventional hydrocarbon reservoirs as well as analyze the effect of complex stress fields on subsurface deformation for problems ranging from large-scale folding and faulting down to borehole stability.
