For natural gas, the compressibility factor value at base conditions is nearly 1, such as 0.99, so that B has to be negative (Fig. 1). Click here to enlarge image Equation 2 shows the second ...

Compressibility Factor: A dimensionless quantity that indicates the deviation of a real gas from ideal gas behaviour under specific conditions of pressure and temperature.

Two separate correlations for predicting the isothermal compressibility of reservoir fluids and crude oils have been developed. One correlation is based on molecular weight; the other, on API ...

Understanding and accurately predicting the compressibility factor of natural gas is pivotal for a range of engineering applications, ... Equation of State (EoS): ...
