Low Gas–Oil Ratio Oils

This chapter defines low gas–oil ratio (GOR) oils and discusses their occurrence. It explains the practical reasons to distinguish low GOR oils from black oils. This chapter explains how to generate pressure, volume, and temperature (PVT) properties for low GOR oils. It also shows that these fluids are not necessarily heavy oils as they sometimes have reasonably low viscosity and can flow easily under normal conditions of temperature. The sequence of calculations to generate PVT properties for low GOR oils is explained through practical example calculations.
