Shales are fine-grained sedimentary rocks
rich in petroleum and natural gas.
Both the Marcellus and Utica Shale were
formed by the accumulation of sediment in a
sea beginning about 417 million years ago
Buried and compressed to produce an
organic-rich black shale

Fracking is the well development process
typically involving injecting water, sand, and
chemicals under high pressure into a bedrock
formation via the well. This process is
intended to create new fractures in the rock
as well as increase the size, extent, and
connectivity of existing fractures.
