Universiti Teknologi Petronas Geosciences and Petroleum Engineering Department Reservoir Rock and Fluid properties Laboratory Lab Experiment No. 3: Permeability Test 1. Objective: To determine the permeability of core plug sample by using the PoroPerm System 2. Introduction The POROPERM instrument is a permeameter and porosimeter used to determine properties of plug sized core samples at ambient confining pressure. In addition to the direct properties measurement, the instrument offers reporting and calculation facilities thanks to its user-friendly windows operated software. Direct measurements: Gas permeability (mD). Pore volume. Core length and diameter. Calculated parameters: Klinkenberg slip factor “b”. Klinkenberg corrected permeability. Inertial coefficients. Sample bulk volume. Sample porosity. Grain volume. Grain density (assuming sample is weighed). The gas permeability determination is based on the unsteady state method (pressure falloff) whereas the pore volume is determined using the Boyles law technique. Length and
