Hydrostatic pressure
Calculate static liquid-column pressure using true vertical height.
Inputs are sent to the server for this calculation without being saved or added to the URL. Saving a scenario stores it only in this browser.
Formula and assumptions
Assumes a static, constant-density liquid column and standard gravity. Use the vertical height of the actual liquid column, not measured bore length. All total pressures are gauge pressures. Friction, gas, temperature-dependent density, pore/fracture pressure and operational suitability are not assessed.
Δp = ρ × 9.80665 × TVD / 100000; p(g) = p_surface(g) + ΔpMethod references
