Natural fractures can improve the permeability of tight rock and are therefore often targeted by oil wells. But where do they occur in the reservoir and how do we find them ?
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.
Fractures, joints
This blog looks at joints contained within zones of deformation bands - how they form and if they are important or not.
