Hydrostatic & Kill-Weight Calc

Hydrostatic head at any depth in either unit system — and the kill weight that balances a given formation pressure.

Method & assumptions
Ph = 0.052 × MW(ppg) × TVD(ft) — SI: ρ·g·h ÷ 1000 (kPa)

0.052 is the field constant (psi per ppg·ft). Kill mud weight balances formation pressure without a safety margin here — add your company trip/kill margin on top.

Engineering aid only — verify results against the applicable code edition and the equipment datasheet before committing to a design.
