Salt Cavern Leaching Simulation (2D)

This 2D companion trades the 3D version's process-plant camera for a readable vertical cross-section of the cavern itself. Thirty depth layers sit beneath an impermeable cap-rock band; fresh water enters through a movable tubing shoe and dissolves the rock-salt bed fastest in the layers just above the injection point, where the water is still nearly fresh, while a nitrogen blanket you can raise or lower shields everything above it from contact and keeps the roof intact. Each layer's local salinity climbs toward the 26.3% saturation point as it dissolves, which self-limits further growth — exactly the effect operators use to steer a real cavern's final shape by moving the tubing string and blanket depth over the life of the well.
