Porosity is the percentage of empty space within a solid media. Effective porosity is the percentage of void space in which the pore spaces are interconnected. Accurately determining the effective porosity of a petroleum reservoir is important for estimating the total amount of recoverable hydrocarbons within a producing formation.

The BLP-630 Automated Gas Porosimeter was designed to rapidly and accurately measure the effective porosity of a core sample. Three separate volumetric gas reservoirs provide seven (7) possible gas volume combinations to improve effective pore space data for a broad range of core sizes and porosities. It includes an assortment of volumetric core holder inserts to minimize dead space for greater accuracy. And the core holder is secured and release with a quarter turn by hand for quick and easy core loading.

Permeability is a measure of the ability of a fluid to flow through a porous media when subjected to a differential pressure and is mathematically equated by Darcy’s law. The permeability of a petroleum reservoir is one of the most influential parameters in determining the production capabilities of a producing formation. Our Reservoir Permeability Tester was developed to evaluate how fluids affect the permeability of a core specimen. In addition, the unit may be used to evaluate acidizing techniques and to develop typical Acid Response Curves (ARCs).

The Reservoir Permeability Tester (part number 127-00) features a Hassler-type core holder that rotates 90° to allow either horizontal or vertical testing. Manual valves enable forward and reverse injection through the core for up to three separate fluids and Nitrogen gas. All wetted components are made of 316 stainless steel, although Hastelloy is available on request. The unit is housed in a two-piece cabinet with storage below and locking swivel castors for mobility. A PC and data acquisition software are included.
