Permeability

Permeability is one of the key parameters when talking about reservoir or caprock quality. We offer both, permeability to gas and permeability to liquid. Gas permeability measurements can be carried out with e.g. air, nitrogen or helium. Cubic and cylindrical specimens of variable size can be investigated under ambient as well as stressed conditions. Measurement of stressed permeability within a triaxial cell is in particular useful for samples from deep bore holes which tend to micro crack formation under ambient conditions due to stress release. Gas and fluid flow along these micro cracks will lead to artificially high permeabilitiy values. Measurements done under simulated in situ conditions within a triaxial cell close these micro cracks and allow for determination of the correct in situ permeability. Moreover, we provide Klinkenberg-corrected permeability values determined based on the Law of Darcy.

For specimens with permeability higher than 5*10-18 m2 we offer additional flow monitoring with highly accurate and fast-reacting volume flow meters. This can be done while continuing with deformation during triaxial stress-strain tests.
