Steady State Liquid Permeameter

The PMI Steady State Liquid Permeameter is used to measure permeability of samples such as oil well cores, tight gas sandstones, and other low permeability rocks. Liquids such as brine, oil, and other fluids are used. The machine measures drop in pressure and flow rate through the sample during the test. A rock sample is held in the sample chamber and compressive stress is applied. While the sample is under compressive stress, the desired properties are measured. The PMI Steady State Liquid Permeameter is used to determine the properties of cut samples at certain confining pressure. The PMI Automated Liquid Permeability System has been specially designed for testing core samples. Core samples are held in a Hassler type core holder which compresses the sample to the desired pressure. The test is run at ambient temperature. Non-aqueous fluid such as oil, kerosene and aqueous fluid such as brine or equivalent can be used. The instrument measures the rate of a known amount of liquid to compute permeability. The equipment is fully automated. Execution of the test, data acquisition, data storage, & data management are all carried out by PMI Software. Operator involvement is minimal, and the instrument is robust and requires a minimal amount of care.
