A Study on Gas Compressibility Factor for Gas-Condensate Systems

Compressibility Factor for Sour Gas Reservoirs

This paper presents the initial stage of an effort aimed at developing a new correlation to estimate pseudo critical properties for sour gas when the exact composition is not known. Several mixing rules and gas gravity correlations available in the literature are first evaluated and compared. The evaluation is performed on a large database consisting of more than 2000 samples of sour gas compos...

Estimation of Gas Mixture Compressibility Factor and Viscosity based on AI and Experimental DataEstimation of Gas Mixture Compressibility Factor and Viscosity based on AI and Experimental Data

Compressibility factor and viscosity of natural gasses are of great importance in petroleum and chemical engineering. To calculate the natural gas properties in the pipelines, storage systems and reservoirs, the exact values of gas compressibility factor and viscosity are required. A new method that allows accurate determination of compressibility factor and gas viscosity for all types of: swee...

Simulation Study of Enhanced Condensate Recovery in a Gas-Condensate Reservoir

A New Correlation Based on Multi-Gene Genetic Programming for Predicting the Sweet Natural Gas Compressibility Factor

Gas compressibility factor (z-factor) is an important parameter widely applied in petroleum and chemical engineering. Experimental measurements, equations of state (EOSs) and empirical correlations are the most common sources in z-factor calculations. However, these methods have serious limitations such as being time-consuming as well as those from a computational point of view, like instabilit...
