Asphaltene Phase Behavior Study

Objective:

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.

Description

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
