The definition of a “volatile fluid” is a fluid that easily evaporates or vaporizes. This definition gives rise to the name “volatile oils.” These systems develop larger gas phase volumes, when compared to Black Oils , for comparable pressure drops when entering the two-phase region of the phase envelope.
Some basic properties of Volatile oils are:
-
1,000 < GOR < 8,000 scf/STB
-
Density between 45 - 60 API
-
Oil FVF > 2.00 (high shrinkage oils)
-
Light brown to green in color
-
C7+ composition > 12.5%
