How to use this app:
Give your scores to DHI observations and you will get back-of-the-envelope R-ratio (hydrocarbon/nonhydrocarbon probabilities) plus Revised Pg according to Bayesian update.

DHI scheme in relation with R values:
  • - No DHI, R = 0;
  • - Low Grade, R = 1;
  • - Moderately Strong, R=2;
  • - Strong, R=3.

  • Typically, high grade DHIs (R: 2-3) have a technical success rate > 50% with commercial success ~30%
