Monte Carlo Volumetrics

Estimate in-place volumes using Monte Carlo simulation in Excel. Define input distributions, account for parameter correlations, and generate probabilistic outputs without external software.

‍

Key features

Distribution setup

Define distribution type and input ranges for key volumetric parameters (area, thickness, NTG, porosity, saturation, formation volume factor).

‍

Parameter correlation

Apply positive or negative correlations between variables using a correlation matrix.

‍

Output analysis

• P10, P50, P90 estimates
• Distribution charts
• Cross-plots between variables
• Correlation heatmaps
