Modelling Iodine Production Using Coupled Geochemistry in CMG GEM

Iodine production from subsurface brine reservoirs is governed by a complex interplay of fluid flow, gas solubility, and geochemical reactions. 

Using CMG’s GEM simulator, a fully integrated workflow was developed to:

• Model iodine production from brine systems 
• Capture gas dissolution effects (CH₄, CO₂) 
• Simulate mineral reactions controlling iodine release 
• Evaluate water injection and recycling strategies 

Outcome: A predictive framework that enables operators to optimize iodine recovery, reduce uncertainty, and better manage reinjection strategies.
