Core Porosimeter

Part #127-20

Core Porosimeter

OFITE's Core Porosimeter was designed to rapidly and accurately measure the effective porosity of a core sample. Porosity is defined as the percentage of void within a solid media. Effective porosity is the percentage of void within a solid media in which the pore spaces are interconnected. It is imperative to accurately determine the effective porosity of a petroleum reservoir when estimating the total amount of recoverable hydrocarbons within a producing formation. OFITE's Model 350 Core Porosimeter was designed to precisely measure the effective porosity of a core sample.

Method of Operation:

A sample is placed into the air-tight core holder and pressure is applied to a reservoir of known volume. After the pressure has stabilized, a valve is opened, which permits the gas within the reservoir to expand into the core holder. After equilibrium is reached, the new pressure of the system is measured and recorded. The effective porosity of the core specimen may be calculated by the use of Boyle's Law (P1V1 = P2V2) in conjunction with the bulk volume of the sample. The variables V1 and V2 are constants that are dependent upon the geometry of the unit and the effective porosity of the core.
