Hydrostatic Pressure Calculator
Hydrostatic pressure is the base of every well-control calculation. Enter mud weight and TVD to get bottom-hole hydrostatic pressure and gradient.
Formulas
Field units
P (psi) = 0.052 × MW (ppg) × TVD (ft)Metric units
P (bar) = 0.0981 × SG × TVD (m)Worked example
GIVEN
- MW = 10 ppg
- TVD = 10,000 ft
WORKING
- P = 0.052 × 10 × 10,000
Hydrostatic = 5,200 psi
FAQ
Does hole angle matter?
No — only TVD matters. Use measured depth only for volume calculations.
