Method measures commingled production, pipeline components

An analytic method discriminates and quantifies the constituent cuts in commingled reservoir production and pipeline streams.It uses Fourier transform infrared spectrometry (FT-IR) on crude oils and works even if the constituents exhibit minute compositional differences.The quantitative analysis uses the IR spectrum band between 3,150 cm-1 and 2,750 cm-1. This region provides characteristic oil "fingerprints" whose shape is directly related to composition.The method can be used as a rapid and inexpensive monitoring tool for applications such as production allocation in commingled reservoir streams and pipelines, multilayer hydrocarbon reservoir management, reservoir compartmentalization, ...
