The future availability of energy resources depends on improved detection of resources and the completeness (efficiency) of recovering the resources. For hydrocarbon resources, typical recovery efficiency can range from just a few percent to ~70%. Thus, vast energy resources are left behind by conventional extraction techniques. To supply the growing world population will require technology that improves our recovery of energy resources.
Davatzes Group focuses on mapping and modeling the mechanical interaction among slipping fault segments to understand variation in damage that channels and traps hydrocarbons. As well as understanding the dependence of mechanical and hydrologic properties on mineralogy resulting from the interaction of deformation and chemical alteration.
- Geologic mapping of fault geometry, fault zone architecture, and fracture patterns
- Geomechanical analysis including the characterization of natural fracture populations and in situ stress
- Laboratory characterization natural fractures including alteration mineralogy, healing history, porosity (including 3D porosity mapping with high resolution XRay-CT)
- Numerical modeling of stress field variation and fracture formation and slip prediction
- Time series analysis of pumping, seismicity, and deformation records
- Statistical characterization of fracture and stress heterogeneity
