Helium Porosimeter
The Helium gas Porosimeter determines the sample’s (1 inch or 1.5-inch diameter) grain and pore volume via an isothermal helium expansion and works based on Boyle’s and Charles’ law. Porosity is usually expressed as a percentage of the core plug’s total volume. The device tolerates an injection pressure of up to 10 bar (higher pressure is available upon request). Each sample matrix cup is interchangeable and is provided with stainless steel billets for calibration.

Helium Porosimeter at Confining Pressure
Read moreNormally, the porosity of the cores is measured without applying confining pressure on the samples. Although the confining pressure is not able to significantly affect the porosity value, it may lead to a huge deviation on the estimated value of the original oil in place. This device measures the porosity of the core samples while under confining pressure. This equipment can be used for grain density measurement at net confining stress. Moreover, Porosity is usually expressed as a percentage of the core plugs’ total volume.
