Formation database

Store the rock you actually treat — porosity, permeability and fracture gradient. Mark one active and the pressure advisor and physics dashboard use its gradients and rock physics instead of hardcoded defaults.

Add a formation

Porosity, permeability and fracture gradient are required. Leave the overburden gradient blank and it is derived from porosity through the bulk-density mixture law; leave Poisson's ratio or tensile strength blank to keep the platform default.

Formation name

Basin / field (optional)

Porosity (fraction)

Permeability (mD)

Fracture gradient (ppg)

Pore gradient (ppg, optional)

Top depth (ft, optional)

Base depth (ft, optional)

Overburden gradient (psi/ft, optional)

Poisson's ratio (optional)

Tensile strength (psi, optional)

Notes (optional)

Bulk density 2.520 g/cc → overburden gradient 1.093 psi/ft when no explicit value is stored. Permeability 5.00e-4 mD (tight leak-off) is recorded for provenance and does not alter pressures.
