Corrosion driven by carbon dioxide (CO₂) and hydrogen sulphide (H₂S) remains one of the critical integrity challenges in oil and gas production and transmission systems.
When combined with multiphase flow, water chemistry, and operational variables, these acidic gases create a highly aggressive and complex environment capable of severe degradation of carbon steel infrastructure.
To support engineering assessment and integrity decision-making, we have developed a multiphase CO₂/H₂S corrosion prediction model (O&G-Corrology®) tailored for production and transmission systems.

The O&G-Corrology® integrates:
* CO₂ and H₂S corrosion rate prediction for carbon steel.
* Advanced multiphase flow modelling to capture flow-driven effects.
* Aqueous chemistry calculations (pH, ionic strength, speciation).
* Consideration of chlorides, O₂, oil wetting, water cut, and scale effects.

This comprehensive approach enables engineers to quickly assess:
* Corrosion risk.
* System aggressiveness.
* Operational sensitivity.
* Integrity management strategies.
