Advanced Permeability Porosimeter

The PMI Advanced Permeability Porosimeter is a versatile and accurate instrument used to determine properties such as particle size, particle distribution, pore tortuosity, pore number fraction, pore throat ratio, pore fractional dimensions, permeability, material compressibility, total pore volume, surface area, and bulk and absolute densities of solid and powder samples. With unlimited user-defined data-points, automated data collection and reduction, non-destructive testing, and the least mercury exposure of any porosimeter on the market, PMI’s Permeability Porosimeter is safe, reliable, and precise. It also allows testing under ambient or elevated temperatures to simulate actual operating conditions.

Automated Humid Air Porometer

Advanced Automated Porometers yield very objective, accurate and reproducible results, considerably reduce test duration, and require minimal operator involvement. The machine is fully automated and designed for linear turbulance-free test gas flow. The pressure is measured close to the sample and therefore, the correction term in the differential pressure measurement is minimized. Required amount of pressure is uniformly applied to the o-ring seals on the sample and the need for hand-tightening of the cap on the sample chamber is eliminated. Automatic addition of wetting liquid reduces test time appreciably. This sophisticated instrument has found applications in a wide variety of industries.

Automated Pulse Decay Porosimeter/Permeameter

The rock core sample is loaded in a holder and confining pressure is applied. The system is then charged with test gas to the desired pore pressure. Adequate time is given to allow this pressure to fully saturate the sample. After reaching equilibrium the upstream and downstream portions of the system are isolated from each other. A pulse is then created by raising the upstream pressure (or lowering the downstream pressure). Data is recorded throughout this process and is used in conjunction with known system volumes to calculate gas flow rates and permeability.

Confining Pressure: Up to 5000 psi with a suitable pressure transducer be provided for measuring the pressure up to 5000 psi.Core Holder: Hassler type of core samples of 1.0 inch and 1.5 inch diameter for grain volume/ pore volume measurement.

Consistometer

PMI’s Computer-Controlled HPHT Consistometer, Model PMI‑CM‑40K, is designed to measure the viscosity and thickening behavior of cement slurry under high pressure and high temperature conditions. The instrument features a rotating slurry cup that operates at speeds up to 150 rpm and a stationary paddle‑type sensor. User‑defined temperature and pressure conditions are applied to the test chamber while the magnetically driven cup rotates and the slurry flows against the paddle sensor. The torque applied to the paddle during cup rotation is used to determine the slurry consistency. This instrument is used to evaluate cement thickening behavior under a wide range of downhole well conditions. The instrument is designed for easy operation via computer control, enabling accurate and reliable testing with minimal preparation time. The innovative hardware design makes the instrument easy to set up, easy to use and easy to clean. The custom PC software included with each unit allows the user to construct test sequences, run tests, and interpret test results quickly and with efficiency.

Multipoint Simultaneous Pore Structure Analyzer

All the models of this instrument are similar. In one model the sheet to be tested is made to pass through two flat parallel plates. The top plate has straight through cylindrical holes to accommodate inverted cup shaped sample chambers and about two inch diameter samples. The bottom plate also has through holes aligned with the holes in the top plate. There are five chambers over the product width of about twenty inches. The chamber has gaskets at its bottom rim to make a pressure tight seal with the sheet when the chamber goes down the hole in the top plate to make contact with the sheet. The top of the chamber is connected to the pressure transducer to measure pressure just above the sample. The sample chamber is also connected to a gas line to supply pressurized gas to the chamber. The outlet of a small valve for discharging a specified amount of wetting liquid on the sample in the sample chamber is allowed to pass in to the chamber. The valve is computer controlled to discharge the wetting liquid at the desired time.
