Compressibility in gas

WebFor most reservoir engineering calculations, the gas formation volume factor (and Gas Compressibility, c g, and Gas Density, ρ g) can be determined from the Real Gas Law, Equation 3.27: p V = Z n R T. Where: p is the pressure of interest, psi; V is the volume, ft 3; Z is the oil super-compressibility factor, dimensionless WebThe calculation in figure 1 shows a compressibility factor of 0.7. In this case, assuming a compressibility factor of 1.0 when it is really 0.7 would result in a Cv calculation that would be about 20 percent high. When the compressibility factor decreases, so does the calculated required valve capacity (C v or K v). Figure 1.
