However, natural hydrocarbon gases are not ideal gases and the compressibility factor, z, is a function of pressure as seen in Figure 1.18 [17]. At low pressures, z decreases as pressure increases and dz/dp is negative; thus, cg is higher than that of an ideal gas. At high pressures,...
Gas compressibility factor or Z-factor for natural gas system can be determined from Standing-Katz charts using the pseudocritical gas pressure and temperatures. These charts give accurate values for Z-factors. Reservoir simulation softwares need accurate correlations to estimate the values of Z-factor...
Old correlations give good estimation of Z-factor at low gas reservoir pressures below 41.37 MPa (6000 psia), at high pressures the error started to appear. The developed correlation is a function of pseudoreduced pressure and temperature of the gas which makes it simpler than the existing ...
Compressibilityis expressed as the multiplier for the perfect gas law to account for deviation from the ideal. At a given set of conditions of temperature and pressure: (18-1)PV=ZNRT where Z =compressibility factor, usually less than 1.0 ...
Figure 1– Compressibility factor at different pressure and temperature At a reservoir condition, gas is mixtures of several gas molecules therefore it is impossible to have the z-factor chart made to match with each composition of gas in a reservoir. Therefore, the Principle of Corresponding State...

at pressures of 6-12 MPa.The effect of EoS on the adsorption increment is small at low and high pressure.The effect of EoS on adsorption not only depends on the EoS used to calculate compressibility factor of CO 2 and also on the volume of reference cell and free volume of sample cell...
Calculate the compressibility factor of the gas at 90°F temperature and 1200 psia pressure. Solution Using Appendix 1, we create the following table showing the molecular weight M, critical temperature Tc, and critical pressure Pc for each of the component gases. The molecular weight of the mix...
