Scorchingly hot granite deep underground can be tapped for energy by opening up cracks in the rock. This potential resource, known as enhanced geothermal energy, requires a clear sense of changes ...

Previous chapters have addressed fracture geometry, physical and geomechanical properties of single fractures, fracture detection, and the interpretation of hydraulic and tracer tests. All of these ...

1. Introduction -- 2. Stress -- 3. Displacement and strain -- 4. Relation between stress and strain -- 5. Loading of brittle rock to failure -- 6. Stress concentration -- 7. Theories of brittle ...

This image shows the variation in permeability in a network of fractures due to quartz dissolving in the fractures. Each plane represents an individual fracture in the network. Fractures are the main ...

This chapter addresses methods for the remote detection and characterization of fractures in the subsurface. These indirect detection methods are mainly geophysical in nature and rely on the physical ...
