Pseudosteady-State Dimensionless Pressure Drop for Horizontal Well

P_D=2\pi t_{DA}+0.5\ln\left(\frac{A}{4(L/2)^2}\right)+0.5\ln\left(\frac{2.2458}{C_{Ah}}\right)+1.385

Analysis inputs

The same base values feed sensitivity, Monte Carlo, contour, and surface analysis.

Vary selected inputs by low/high percentage and rank impact.

Low %High %

Run sensitivity analysis to render a Plotly tornado chart.

Runs in a Web Worker using Latin Hypercube sampling.

VariableDistributionIterations

Run Monte Carlo to render the histogram and summary statistics.

Vary two inputs and render both 2D contour and 3D surface views.

X variableY variable

Build a grid to render Plotly contour and 3D surface charts.
