المستخلص: The compressibility factor (Z-factor) of natural gases is necessary in many gas reservoir engineering calculations. Knowledge of the pressure- volume - temperature (PVT) behavior of natural gases is necessary to solve many petroleum engineering problems such as gas reserves, gas metering, gas pressure gradients, pipeline flow and compression of gases. However, the value of compressibility factor should be computed when PVT data are not available. For this purpose some developed empirical correlation for the Libyan natural gases were tested to find out they are applicable or not. Six empirical correlations were tested for estimating the (Z-factor). Estimated Z-factor values by these empirical correlations are also compared with a large of lab z-factor measurement consisting about 90 sample from two Libyan oil Field are (ten wells from Amal oilfield and five wells from Tibiste oilfield). The results obtained shows that some of those correlations are valid for the Libyan natural gases, and some of them are not applicable due to their high average absolute error.
