Processing a reservoir fluid sample includes separating the reservoir fluid sample into a vapor phase stream and a liquid phase stream, assessing a composition of the vapor phase stream, sampling a property of the liquid phase steam, and assessing a volume of a components of the liquid phase stream
Processing a reservoir fluid sample includes separating the reservoir fluid sample into a vapor phase stream and a liquid phase stream, assessing a composition of the vapor phase stream, sampling a property of the liquid phase steam, and assessing a volume of a components of the liquid phase stream based at least in part on the sampled property of the liquid phase stream. A system for processing a reservoir fluid sample includes a volumetric receptacle adapted to accept the reservoir fluid sample, a phase separator configured to receive the reservoir fluid sample from the volumetric receptacle and to separate the reservoir fluid sample into a vapor phase stream and a liquid phase stream, a gas chromatograph arranged to receive the vapor phase stream from the phase separator, and a liquid flow meter configured to detect an interface including at least one component of the liquid phase stream.
