Advanced Pulse Decay Permeameters

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 Pressure Decay Permeameter is used to determine the properties of cut samples at certain confining pressure.

  • APDP-10K-HP-101
      Automatic and highly accurate system for determining rock properties such as permeability and Klinkenberg correction factor at overburden pressure. The system uses a steady state pulse decay technique for the permeability measurement.
    • Advanced fully computer controlled system that allows the operation for both automatic and manual modes and can provide precise monitoring and data acquisition
    • Custom-designed hydrostatic core holder for core samples upto 3.0" in length and working upto the confining pressure of 10,000 psi and temperature 125°C
    • Automatic confining pressure control system. Confining pressure with intensifier
    • The sample loading and unloading is simple and takes only a few minutes. Computer-controlled differential pulse generator increases the upstream pressure and equally decreases the downstream pressure to insure a constant median pressure gradient in the core sample and reduces the time to achieve a steady measurement
    • The system is consisting of advanced computer controlled automation package that allows precise data acquisition and handles all control measurement, data collection and report generation
    • Able to test up to 7 days or more continuously
    • All key components are insulated to eliminate possible error due to fluctuation in ambient temperature
    • All wetted parts (Tubing, Connector and Valves) are constructed of highly corrosion resistant materials Hastelloy and SS 316
    PMI-APDP-5K-C-1
