Permeability is the primary control on fluid flow in the Earth's crust
and is key to a surprisingly wide range of geological processes, because
it controls the advection of heat and solutes and the generation of
anomalous pore pressures. The practical importance of permeability - and
the potential for large, dynamic changes in permeability - is
highlighted by ongoing issues associated with hydraulic fracturing for
hydrocarbon production ("fracking"), enhanced geothermal systems, and
geologic carbon sequestration. Although there are thousands of research
papers on crustal permeability, this is the first book-length treatment.
This book bridges the historical dichotomy between the hydrogeologic
perspective of permeability as a static material property and the
perspective of other Earth scientists who have long recognized
permeability as a dynamic parameter that changes in response to
tectonism, fluid production, and geochemical reactions.
