  The drilling of geothermal energy, CO2 sequestration, and wastewater
injection all involve the pressurized flow of fluids through porous rock, which
can cause deformation and fracture of the material. Despite the widespread use
of these industrial methods, there is a lack of experimental data on the
connection between the pore pressure rise, the deformation and permeability
changes in real rock. In order to address this gap in the literature, this
study developed an artificial rock material that can be deformed and fractured
at low pressures. By controlling the porosity, permeability, and strength of
the material during the sintering process, it is possible to mimic various
types of rock. The artificial rock was designed to accommodate radial flow and
deformation, allowing for the tracking of deformation by monitoring the flux
and driving pressure and thus calculating the permeability changes under
various pressure conditions. The study was able to examine the impact of both
ductile and brittle deformation on the permeability during pressurized flow,
which were captured by two models that were adjusted to this scenario. This
study provides a link between pressurized flow, rock formation permeability and
ductile to brittle deformation, that can constrain risk assessment to
geothermal energy and CO2
