Oilfield & Mining Calculators
Free calculators and field references for oilfield, drilling, and mining engineers. Casing burst pressure, drill string weight, blast-hole pattern, pit slope, weir flow — imperial or metric, no signup.

Tip
Every calculator supports imperial and metric, shows a worked
example, and ties to the API / NACE reference tables. Burst pressure
uses the API 5CT / 5C3 internal-yield factor (0.875) — not raw Barlow.
Always cross-check against mill-certified MTRs.
Weak or no signal on every land rig pad
Sign the kill sheet before it goes on the DDR
Oil & Gas Toolkit runs kill-mud, ECD and pump output from SIDPP and TVD, shows the math, and prints a kill sheet. No signal, no login. Pay once.
CalcSpec tools are estimators for qualified drilling engineers, mining engineers, and geotechs. Results do not replace API / NACE standards, mill-certified MTRs, a licensed professional engineer's stamp, or site-specific geotechnical investigation.
