Configuration

📊 Porosity Uncertainty

AI Model model used for AI prediction + P10/P50/P90 uncertainty Select Porosity Log porosity/density/neutron logs from LAS file Depth Range filter chart by min / max depth from LAS file

Depth Unit:

–

Porosity Curve Range optional X-axis range for uncertainty plot; leave blank to use default auto range

Curve Display:

–

Default keeps the current porosity scale. Example: 0 to 0.25 fraction, or 0 to 25%.

📊 Saturation Uncertainty

AI Model model used for AI prediction + P10/P50/P90 uncertainty Select Saturation Log resistivity logs from LAS file Depth Range filter chart by min / max depth from LAS file

Depth Unit:

–

Saturation Curve Range optional X-axis range for uncertainty plot; leave blank to use default 0–1 scale

Curve Display:

–

Default keeps the current saturation scale. Example: 0 to 0.6 fraction, or 0 to 60%.

Porosity Uncertainty: P10 / P50 / P90

Depth vs Porosity — P10 (dotted, optimistic), P50 (solid, best estimate), P90 (dashed, conservative)

Saturation Uncertainty: P10 / P50 / P90

Depth vs Water Saturation — P10 (dotted, low Sw), P50 (solid, best estimate), P90 (dashed, high Sw)
