Gas Permeametry

The Kirk Petrophysics laboratory is equipped with a precision gas permeameter to measure air permeability using the steady state method.

The unit includes a Hassler type core holder capable of testing samples from 1” to 1.5” diameter with applied confining/pore pressures up to 10,000 psi.

The quick fit core holder allows the efficient loading/unloading of samples improving the turnaround on routine and special core analysis projects.

Probe Permeametry

Kirk Petrophysics provide a portable, high precision solution to measure permeability at the wellsite or Core Analysis Laboratory on irregular shaped core samples, slabbed core or resinated core.

The instrument measures the gas permeability by applying a probe on the sample through which Nitrogen is injected. The flow rate is then monitored to provide a relative, steady state permeability.

Measurements can be made at 1cm intervals – enabling high resolution permeability profiles to be constructed for heterogeneous reservoirs.

Mini Permeametry

For quality control, qualitative assessment, quick data acquisition at the wellsite or immediate access to relative permeability during a core viewing, Kirk Petrophysics utilise a portable, handheld air permeameter.

The unit is particularly useful for permeability measurements of the rock matrix or effective fracture apertures on outcrops and at the core scale.

For intact rock, the permeability measurement range is from approximately 1 milliDarcy to 10 Darcy's. Similarly, fracture apertures from approximately 20 microns to 2 millimeters can be determined.
