Fold related fractures form as a result of local stresses and strains during the folding process.
Here we look at the Stearns model, which can be used to guide fracture population in a fracture model.
Faults, slickenlines
This blog shows that slickenlines are scratches on the surfaces of shear fractures. The state of stress on a shear fracture can be predicted by Mohr circles.
Fractures, Geothermal
This blog addresses why wettability is important in the recovery of oil from fractured chalks.
There are 2 basic types of natural fractures that need to be studied when characterising naturally fractured reservoirs - whether it be a geothermal or hydrocarbon reservoir. These are extension and shear fractures.
Faults, Folds
This blog examines some key features of thrust systems with an example from seismic data offshore Namibia and from a hand specimen onshore UK.
