Abstract:

The present invention is directed to a method for allocating revenue or taxes to individual fluid streams commingled during an oil and gas production process, the method includes commingling fluid streams to produce a commingled fluid stream; (2) utilizing a process simulation model to predict a phase change of each fluid stream in the commingled fluid stream, wherein the process simulation model predicts the phase change of all the individual fluid streams in the commingled fluid stream the phase change of each individual fluid stream in isolation of the commingled fluid stream, the phase change of all the individual fluid streams in the commingled fluid stream absent a single fluid stream; and (3) determining the difference in phases between the calculated phase change of all the in individual fluid streams in the commingled fluid stream and calculated phase change of all the individual fluid streams in the commingled fluid stream absent a single fluid stream.
