Gas Permeameter

The permeability of a core plug to gas can be measured either using the steady-state or unsteady-state technique. This measurement shows the capability of the core to transport fluids through its pore/throat system. Higher permeability leads to a lower pressure drop when the fluid passes through the system. The steady-state approach is the most accurate, reliable, and convenient technique to measure the permeability of a core plug. It is suitable for mid to high-permeable core plugs in which Darcy’s law for the gas system is applied. As this technique takes a long time to be completed for tight core plugs, the unsteady-state approaches must be used for tight core plugs. Also, the unsteady-state permeability measurement is a faster technique to determine the permeability of the core.

Helium Porosimeter

This instrument is used for Routine Core Analysis (RCAL), in which effective porosity (interconnect porosity) and grain density of a particular core plug are determined using an inert gas with a small molecular size, such as helium. Helium is used because it has the smallest molecular size among the inert gases. Therefore, it can easily penetrate core plugs with small pores. Boyle’s Law for isothermal ideal or real gas systems is the base for the porosity calculation in this equipment.Boyle’s Law for isothermal ideal or real gas systems is the base for the porosity calculation in this equipment. The helium porosimeter involves a core holder chamber with or without confining pressure.

Combined Poroperm

PERM Inc. Instruments is capable of combining different units into one integrated system. Please contact us if you need any recommendations for your application.

A popular option is combining a porosimeter and a permeameter. This makes taking measurements easier for the end user. Once the core plug is in the core holder, the operator can run either porosity or permeability measurements.

Core Saturator

An essential apparatus for the oil and gas industry, the Core Saturator is used to fill a core plug with a particular fluid (either oleic or aqueous phase). It is the main unit for core preparation before core flooding tests. By saturating a clean and dry core plug, the porosity and pore volume of the core plug can be determined by measuring the mass of the core plug before and after the saturation.

Capillary Pressure

The Capillary Pressure Apparatus assists with Special Core Analysis (SCAL) by determining the capillary pressure-desaturation curve of a particular core plug (or multiple core plugs) and the corresponding pore size distribution using an inert gas, such as nitrogen. The high-pressure chamber of this apparatus is equipped with a porous plate with a 218-psi threshold pressure, which does not allow gas to enter its pore spaces if the applied injection pressure is less than 218 psi. A humidifier is included with this apparatus to ensure that the injected gas phase is saturated with water. In addition, the capillary pressure measurement can be run with low- and high-pressure modes, resulting in more accurate measurements depending on the pore-size distribution. A level indicator can show the water level inside the humidifier of the unit.
