Quantifying Subsurface Uncertainty – Facies Classification and Petrophysical Regression Examples

Presented by Kushwant Singh (VGS & Associates)


Uncertainty or risk is conveyed by predictions sets and intervals rather than single predictions.
Conformal prediction specifies a coverage which specifies the probability that the outcome is covered by the prediction region.
For facies classification, we get prediction sets – for numerical regression, we get prediction intervals (P90-P50-P10, etc.)
