This blog focuses upon stylolites which are structures that either form during burial or by later tectonic movements and have a serrated appearance on rock surfaces.
Deformation bands are fault-like structures that reduce the reservoir quality of otherwise good quality sandstones. Here we look at their impact upon effective permeability, which has implications during reservoir development.
Deformation bands can compartmentalise reservoirs, causing challenges for hydrocarbon production. Here we look at the New Red Sandstone on Arran which is host to an impressive network of deformation bands.
