Pipeline Flow Modeling
Ammonite Corrosion Engineering staff and associate engineers, inspectors and technicians have multiple years of experience in corrosion assessment, flow modeling, and integrity management.
Modeling and Assessment Capabilities
- Steady state modeling of hydraulic and thermal conditions.
- Single phase and multiphase modeling of Dry Gas, Wet Gas, Acid Gas, Gas Condensate, Light Oil, Heavy Oil, Water, Emulsion and Steam systems.
- Diagnosis and analysis of flow problems and provision of data for use in integrity and corrosion assessments of pipe and well condition.
- Equation of state calculations. The creation of phase envelopes for system fluids will reveal bubble points which can expose locations to acidic attack when CO2 and H2S are released from the liquids phase.
- Calculations of liquid and gas shear stresses on the pipe wall in fast moving systems. This helps to determine if inhibitor treatments will have sufficient contact with the metal surface.
- In multiphase operations; determination of flow regime and areas of liquid holdup to help predict potential corrosion areas.
- Assessment of temperature profile and potential degradation mechanisms that may result.
- Assessment of erosion potential if there are fast moving fluids, or if solids are present.
- Flow type determination and hydrate prediction.
Pipeline Flow Analysis
Through our parent company, OEL Projects Ltd., we can analyze pipeline flow regimes (steady state and transient) to determine flow types including liquid hold-ups (stagnant regions), slugging, dispersed flow and others. Knowledge of flow types assists in selecting corrosion inhibitors and determining pigging schedules.
