The Matrix Permeameter and Porosimeter is designed for the evaluation of shale reservoirs. S-Pore 200 not only provides a precise method for determining matrix permeability on crushed oil or gas shale samples, but also measure the porosity of core samples.
When we do the matrix permeameter model, a shale sample is crushed and sieved between 20 to 35 US Mesh screens to yield a sample with a diameter between 0.5 mm to 0.853 mm. Approximately 30 to 50 grams of this crushed and sieved sample is placed into the test chamber of the S-Poro 200. Helium, at approximately 200 psig, is then expanded into the test chamber. The pressure decline curve is then recorded for 5 to 30 minutes. A simulator history match of the pressure decline curve then yields the matrix permeability of the shale sample.
The porosimeter model is based on the Boyle’s and Charles’ law expansion of helium gas and is used for direct grain volume and poro volume measurement in auxiliary cell at isothermal conditions. Subsequently, porosity and gain density can be derived from the direct measurements. Our software will get calculation of the gain volume and porosity.
