This article covers all formulas that are used while well control situations on the drilling rig ( Check also: Drilling rigs Types).

Pressures Formulas

HYDROSTATIC PRESSURE (all depths TVD):

Constants:

- PPG x FT x .052 = PSI,
- SG x FT x .433 = PSI,
- SG x MT x 1.42 = PSI,
- PPG x MT x .171 = PSI,
- SG x MT x .098 = BARS,
- PCF x FT x .0069 = PSI,
- SG x MT x .1 = kg/cm2
- SG x MT x 9.8 = kPa,
- Kg/m3 x MT ÷ 102 = kPa,
- PPG x MT x 1.176 = kPa,
- PPG x FT x .358
