A similar technique is used to create improved permeability in underground geothermal reservoirs.Squeezing oil from Permian shale could get harder and more expensive in the years ahead for those who run out of higher-quality source rock.
Shale is most often dark gray or black but can be almost any color including red, green, and brown. It is very fine-grained, made of particles invisible to the naked eye. It has a layered, laminated appearance with many thin, parallel beds. The edges of shale are usually sharp due to its fissile tendency. Black Shale.This Mississippian shale is not exposed in region that has been cited as type locality of Caney shale, where all Carboniferous rocks beneath Atoka formation are Pennsylvanian age.
