Many natural rock fractures contain minerals or cements which reduce their permeability and the permeability of the fracture network. Here we look at some examples in fractured (N Sea analogue) Permian sandstones and dolomites.
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.
Fractures
This blog describes the value of a geomechanical approach to fracture prediction; for example thin beds often have more fractures than thick beds.
Deformation Bands, Faults
This blog looks at some key features of zones of deformation bands. Featured are 2 outcrops of Permian age sandstone from Scotland, UK.
