POSC Specifications: Epicentre Version 3.0 | Relational Implementation |
These are the PVT properties of a vapor fluid defined at given pressures, temperatures and dew point pressures. The pressure, temperature and dew point values are optional but should always be recorded, if available. When the dew point is not defined, it is assumed that the fluid is saturated (that is, the gas is a wet gas and the dew point pressure is the fluid pressure). When the dew point is less than the fluid pressure, the gas is a dry gas.
