Abstract:
1. A method of analyzing a multiphase fluid flowing through a tubular, the multiphase fluid comprised of a plurality of constituents, the method comprising the steps of: flowing a multiphase fluid through a first tubular; separating a sample multiphase fluid flow from the multiphase fluid flowing through the first tubular; flowing the sample multiphase fluid flow through a second tubular; and determining at least one property of the sample multiphase fluid flow using at least one multivariate optical element (MOE) calculating device, the at least one MOE calculating device positioned along the second tubular; and wherein the group of constituents includes at least one of the groups of constituents selected from the group consisting of: C1-C4 hydrocarbons, C1-C8 hydrocarbons, C1-C4 hydrocarbons, C4-C5 hydrocarbons, C4-C100+ hydrocarbons, asphaltenes, and SARA.
