Wellbore Genius

Cross-well pressure interference tomography

Inverts multi-well pressure-gauge histories into a voxelised 3D permeability field via Theis superposition + Levenberg-Marquardt with Tikhonov smoothness. Ships preloaded with a synthetic sand-channel demo; overwrite the observations to invert real gauge data.

Wells & interference pairs (demo)

W1 pulses at 700 bbl/d; W2/W3/W4 observe Δp. Truth field has a high-permeability (80 mD) channel through the mid-y row.

W1: (200, 200, 30) ft · q=700 bbl/d

W2: (1800, 200, 30) ft · observer

W3: (200, 1800, 30) ft · observer

W4: (1800, 1800, 30) ft · observer

W1→W2: 12h=-1.46psi, 36h=-1.31psi, 96h=1.43psi, 240h=0.95psi, 480h=3.40psi
W1→W3: 12h=-0.28psi, 36h=-0.10psi, 96h=-0.48psi, 240h=2.95psi, 480h=7.93psi
W1→W4: 12h=-0.73psi, 36h=-1.03psi, 96h=0.81psi, 240h=0.69psi, 480h=1.93psi
