Cement Slurry Design Calculator

Calculate cement slurry density, yield per sack, water requirement, and total sack count for primary and squeeze cementing operations.

Inputs

Cement Specific Gravity (SG)

Class G/H: 3.14-3.20

Water-to-Cement Ratio (gal/sk)

Class G neat: 5.2 gal/sk

Slurry Volume Required (bbl)

Additive SG (if used)

Set to 1.0 if no additives

Additive Concentration (% BWOC)

By weight of cement

Equations

Slurry yield: Y = (V_water + V_cement + V_additive) / 42 [bbl/sack]

Slurry density: ρ = (lb_cement + lb_water + lb_add) / (gal × 8.33) [SG]
