Wax Phase Behavior Study

Objective:

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

Description

A Wax 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 WDE (wax deposition envelope) and Oil Gelling Envelope (OGE). 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 wax phase behavior model

• Simulate the fluid's WDE

• Simulate the fluid's Oil Gelling Envelope (OGE)
