Well Stream Specific Gravity
Gas mixtures that produce condensate at surface conditions may exist as a single-phase gas in the reservoir and production tubing.
If well stream properties are desired at conditions where the mixture is single-phase, surface gas and oil properties must be converted to a well stream specific gravity. This gravity should be used to estimate pseudocritical properties.
