Asphaltene Phase Behavior Study


Develop a PARA fluid characterization capable of simulating the PVT and Asphaltene phase behavior of a hydrocarbon fluid. This study is a precursor to the Asphaltene Formation Damage Study.


An Asphaltene Phase Behavior Study involves a sequence of tests and computer simulation leading to the development of a PVT-tuned PARA (Paraffin-Aromatic-Resin-Asphaltene) EOS fluid characterization and simulation of the fluid's ADE (asphaltene deposition envelope). The flowcharts below give a summary of the steps required to:


  • Obtain representative bottom-hole fluid samples


  • Perform PARA (Paraffin-Aromatic-Resin-Asphaltene) Analysis, PVT Study, and Flow Assurance Diagnostic Study


  • Develop a PVT-tuned PARA EOS fluid characterization


  • Simulate the fluid's P-T Diagram


  • Tune asphaltene phase behavior model


  • Simulate the fluid's ADE
