Oil / Synthetic Fluids
• Metric Conversions
MgCl 2 (g/L) = MgCl 2 (lb m /bbl) × 2.85714
H 2 0 (mL/L) = H 2 0 (gal/bbl) × 23.8086
MgCl 2 (ppm) = % Wt MgCl 2 × 10,000
Cl – (ppm) = MgCl 2 (ppm) × 0.7442
Formulas
• Salt (lb m /bbl water) = Volume increase factor × MgCl 2 (lb m /bbl)
• Specific Gravity
1.00038 + 7,95497 (10 -3 ) (% Wt MgCl 2 ) + 4.38583 (10 -5 ) (% Wt MgCl 2 ) 2
• Volume Increase Factor
0.999074 + 1.58008 (10 -3 ) (% Wt MgCl 2 ) + 7.66303 (10 -5 ) (% Wt MgCl 2 ) 2
• Aw
