Exploration Efficiency Tier Criteria

Well Success Ratio
Well Success Ratio = Number of Successful Explorations / Number of Explorations

This ratio indicates the percentage of exploration wells that resulted in a successful discovery.

Tier 1 - High Hit Rate/High Number of Fields
  • Number of Fields or Discoveries > 100
  • Well Success Ratio > 30%
Tier 2 - High Hit Rate/Low Number of Fields
  • Number of Fields or Discoveries < 100
  • Well Success Ratio > 30%
Tier 3 - Low Hit Rate/High Number of Fields
  • Number of Fields or Discoveries > 100
  • Well Success Ratio < 30%
Tier 4 - Low Hit Rate/Low Number of Fields
  • Number of Fields or Discoveries < 100
  • Well Success Ratio < 30%
