Waterflood History Match Tracer Design

• Goals
• History match primary and waterflood production
• Only match production after 1970
• Earlier production records not available
• Adjust reservoir size and area heteregeneities
• Vary Dykstra Parsons coefficients to obtain
  correct permeability field
• Vary layering to match breakthrough times

Waterflood History Match Tracer Design

• Goals
• Design tracer to understand layering in detail
  predict
• Minimum and maximum breakthrough times
• Concentration profiles
• Tracer volumes
• Sampling schedule

Waterflood Tracer Design - Conclusions

• Primary and recent waterflood history matched
• Tracer design created
• Model will be updated after tracer breakthrough
  to
• Optimize waterflood recovery
• Minimize water production
