USEFUL CALCULATIONS Hydrostatic Heads Approx. hydrostatic head (kPa) = weight (kg) / liter (L) x depth (m) x 9.81 Approx. hydrostatic head (psi) = 0.052 x weight (lbs) / volume (US gal) x depth (ft) True hydrostatic head = gradient (psi/ft) x true vertical depth API Gravity & Specific Gravity (SG) SG = 141.5 / (131.5 + API) API = 131.5 – (141.5 / SG) Pressure gradient = SG x 0.433 (psi/ft) Pressure gradient = SG x 0.206 (kPa/m) BHP of gas column = surface pressure x gas correction factor Drawdown = static BHP - flowing BHP Productivity index (PI) = BPD / drawdown Fresh Water Facts Density = 8.33 lbs/US gallon (998.18 kg/m3) Gradient = 0.433 psi/ft (9.795 kPa/m) Specific gravity = 1 API gravity = 10 Temperature Calculations °F = (°C x 1.8) + 32 °C = (°F – 32) x 0.5555 Weight of Steel Stem Bar Weight pounds per foot = (diameter squared x 8) / 3 Weight lbs/ft = (OD2 in2 x 8) / 3 Weight kilograms per meter = (diameter squared) / 162 Weight kg/m = (OD2 mm2) / 162
