Foam Column Density
Calculate foam column pressure and pumpability
The Foam Column Density calculator evaluates foam accumulation above the pump and determines if conditions allow effective pumping.
| Field | Description |

| Equivalent Gas free Liquid Above the Pump (ft) | Clear liquid height above pump |
| Field | Description |
|---|
| Oil API Gravity (°API) | Oil gravity |
| Water Specific Gravity | Water density relative to fresh water |
| Field | Description |
|---|
| Oil Rate (bbl/day) | Oil production rate |
| Water Rate (bbl/day) | Water production rate |
| Output | Description |
|---|
| Foam above the pump (ft) | Height of foam column |
| Hydrostatic Pressure of Foam Column (psi) | Pressure from foam |
| Average gradient of foam column (psi/ft) | Foam density gradient |
| Pressure Gradient of Foam at the Pump (psi/ft) | Local gradient at pump |
| Output | Description |
|---|
| Gas Free Fluid Specific Gravity | Combined fluid density |
| Gas Free Fluid Gradient (psi/ft) | Clear fluid pressure gradient |
| Minimum Pumpable Fluid Gradient (psi/ft) | Threshold for pump operation |
| Output | Description |

| Percent of Gas Free Fluid Gradient (%) | Foam impact indicator |
Visual gauge showing percent liquid (0-100%) with pumpability indicator:
- Pumpable - Sufficient liquid density
- Not Pumpable - Too much gas/foam for effective pumping
- Diagnose gas lock conditions
- Evaluate need for gas separator
- Assess foam treatment requirements
- Determine if well can pump effectively
