Rock Permeability Testing System
Many of our rock triaxial testing systems can be upgraded to conduct permeability tests using various methods, including steady-state, transient, and pulse-decay permeability.Permeability measurements are performed using one or a combination of two pumps. These pumps apply different pressures at each end of the sample, with the pressure decay at both ends measured over time. A set of end caps for permeability tests is available for each specimen diameter.
STEADY-STATE PERMEABILITY:
This method relies on a constant pressure gradient and requires two separate pore pressure pumps, which create the pressure gradient across the specimen at the top and bottom. The test is conducted using either two separate pumps or our Twin version.
TRANSIENT PERMEABILITY:
This method requires a single pore pressure pump, which controls the pore pressure at the top of the specimen and monitors the pore pressure response at the bottom.
