Abstract: The complex challenges and cost of intervention in acquiring representative subsea fluid sampling has necessitated an optimised novel approach to compositional fluid tracking to improve estimation of the local fluid properties for facility design optimisation and operations of subsea production systems. This enables computation of the local thermodynamic and hydrodynamic equilibrium in a pipeline flow simulation that accurately takes into account the fluid compositional changes in space and time, and continuously calculates physical properties based on the in-situ hydrocarbon and aqueous compositions. The present paper demonstrates confidence in the application of compositional fluid tracking with transient multiphase dynamic flow model on subsea fluid sampling and allocation of each well production.
