Subsea Flow Assurance Course Hydrocarbon Phase Behaviour and Physical Properties

A phase is any homogeneous and physically distinct region that is separated from another such region by a distinct boundary. The most relevant phases in the oil industry are liquids (water & oil), gases (or vapors), and to a lesser extent, solids. As the conditions of pressure and temperature vary, the phases in which hydrocarbons exist, and the composition of the phases may change. It is important to understand the initial condition of fluids to be able to calculate surface volumes represented by subsurface hydrocarbons. It is also necessary to be able to predict phase changes as the temperature and pressure vary both in the reservoir and as the fluids pass through the surface facilities, so that the appropriate subsurface and surface development plans can be made. Phase behaviour describes the phase or phases in which a mass of fluid exists at given conditions of pressure, volume and temperature (PVT).

These relationships are frequently shown graphically as phase diagrams. Phase behavior for single component systems are simple but as more components are added to the system, it becomes complex. A brief look at the phase behaviour of single component fluids or pure substances will foster an understanding of more complex systems.
