Dry Gas is a natural gas composed mainly of methane with only minor amounts of ethane, propane and butane and little or no heavier hydrocarbons in the gasoline range.
Phase diagram
The phase diagram for a dry gas shows that the reservoir is single phase (all gas), and that the surface separator is too.
Characteristics
| Reservoir state | gas |
| Initial GOR | greater than 100,000 scf/STB |
| C7+ Mole Fraction | less than 0.7% |
