Abstract Injection-induced fracture reactivation during hydraulic fracturing processes in shale gas development as well as
coal bed methane (CBM) and other unconventional oil and gas recovery is widely investigated because of potential
permeability enhancement impacts. Less attention is paid to induced fracture reactivation during oil and gas
production and its impacts on reservoir permeability, despite its relatively common occurrence. During production,
a reservoir tends to shrink as effective stresses increase, and the deviatoric effective stresses also increase. These
changes in the principal effective stresses may cause Coulomb fracture slip in existing natural fractures, depending
on their… More >
