Porosity

Porosity is an important parameter for the storage capacity of a reservoir rock, may it be in terms of its potential as a hydrocarbon source or for gas storage.

We offer two porosity measurement methods to choose from: Hg porosimetry or gas porosimetry (applying helium, nitrogen, argon or air); measurements with water as wetting fluid are also possible.

For gas porosimetry, Gesteinslabor applies a gas pycnometer (Micromeretics AccuPyc II 1340; in particular suitable for measurements with He) that is optimised for measurements on cylindrical or cube-shaped specimens based on the general gas law: The specimen is inserted into a tight-fitting and gas-tight cylinder. The very small system volume is adjusted by amounts at will. From the compressed gas volume within the specimen the interconnected pore space can be determined very accurately.

Advantages of gas/water porosimetry compared to Hg porosimetry:

  • specimens are reusable for subsequent investigations
  • fast measurements
  • cost-efficient
