NAME OF EXPEREMENT: Helium PorosimeterNAME OF STUDENT: Kamal Abdurahman

Group: B

SUPERVISED BY: Mr.Ali Kamal

Aim of Experiment:

This test is dedicated to review basic concept of determining

porosity by “Helium Porosimeter “ method.

IntroductionThis test can be used and conduct on a new generation of Helium

Porosimeter Production educational series, and new generation of

Helium with hand-operated valves. HeP is a Helium Porosimeter

for Grain volume determination on samples (standard, irregular or

coated) based on Boyle-Mariotte’s law. Sample is set in matrix

cup; pore volume is deducted from bulk volume. Measurement

system is computer operated. Calibration routine is provided with

the same software.

Theory

The Helium gas expansion porosimeter is based on the Boyle's and

Charles' law expansion of helium gas and is used for direct grain volume

and pore volume measurement in auxiliary cell at isothermal conditions.

Subsequently, porosity and grain density can be derived from the direct

measurements. A data acquisition computer allows for data logging and

calculation of parameters and also calibration data. The instrument

measures grain volume of plug samples of 1" and 1,5" diameter. An

optional full diameter matrix cup can be added for determination of grain

volume of whole diameter core samples. Each sample matrix cup is

interchangeable and is provided with stainless steel calibration check

plugs. An auxiliary core holder for plug and whole diameter core samples

can also be used to measure pore volume at ambient or overburden

pressure. 

Features:

Computerized data acquisition and control

User friendly, Windows™-based program that not only calculates data but

also offers enhanced graphical representations such as grain density

versus rock type for instant quality control checks.

1.0", 1.5" or 30mm diameter grain volume measuring chambers are the

standard models. Others sample sizes are available

Four reference volumes are standard to accommodate core sample sizes

from cuttings to full diameter

Full diameter grain volume chamber available as an option 

Connection to an external coreholder (plug or whole core) for direct

measurement of pore volume at confining pressures
