Chemical and Reactive Transport Processes Associated with Hydraulic Fracturing of Unconventional Oil/Gas Shales

open access: yesChemical Reviews, 2022
Hydraulic fracturing of unconventional oil/gas shales has changed the energy landscape of the U.S. Recovery of hydrocarbons from tight, hydraulically fractured shales is a highly inefficient process, with estimated recoveries of

The role of aseismic slip in hydraulic fracturing–induced seismicity

open access: yesScience Advances, 2019
Hydraulic fracturing accelerates fault creep in stable formations, loading unstable fault regions, resulting in dynamic rupture. Models for hydraulic fracturing–induced earthquakes in shales typically ascribe fault activation to elevated pore pressure or
