Wellbore Genius

Physics Validation Suite

Runs 4 reference scenarios through the well solver and compares each metric against an expected value within an explicit tolerance.

All reference scenarios pass within tolerance.

4/4 scenarios • 12/12 metric checks

Batch run from CSV

CSV must include columns: depthFt, fluidDensityPpg, surfaceTempF, geothermalGradientFperKft, surfacePressurePsi, depletionPsi. Optional columns: label, youngsModulusPsi, poissonRatio, toughnessPsiSqrtIn, sigmaMinPsi, payZoneHeightFt. Each row is run through the well solver and merged with its outputs in the downloaded results.

Upload a CSV or click Run sample to see how the batch runner formats its results and statistics.

Uncertainty analysis (Monte Carlo)

Specify a range and distribution for each input. Each Monte Carlo draw is run through the well solver; the panel reports P5/P10/P50/P90/P95 confidence intervals and histograms for hydrostatic pressure, bottomhole temperature, and bottomhole pressure.

Samples

Random seed

Parameter	Mean	Min	Max	Distribution
Depth (ft)
Fluid density (ppg)
Surface temperature (°F)
Geothermal gradient (°F/kft)
Surface pressure (psi)
Depletion (psi)

Adjust ranges above and click Run to sample.

Optimization wizard

Searches the input ranges with Latin Hypercube or Sobol' low-discrepancy samples, scoring each draw against your objectives. Lower score = better. The convergence plot tracks the best score found so far; the table lists the top candidate parameter sets.

Output constraints (hard min/max)

No hard constraints. Add one to discard candidates whose output falls outside a required range (e.g. BHP must stay below frac pressure).

Parameter ranges (6 — 6 varied, 0 locked)

Lock	Parameter	Mean (locked value)	Min	Max
	Depth (ft)
	Fluid density (ppg)
	Surface temperature (°F)
	Geothermal gradient (°F/kft)
	Surface pressure (psi)
	Depletion (psi)

Locked parameters are pinned to their mean during optimization; only unlocked parameters are sampled within their min/max range.
