Formula 4.23

Density of brine (completion and workover fluids)

Input(s)

$\rho_{m}$: Density of Brine at ambient Surface Pressure and Temperature (lbm/gal)

$C_{t e}$: Coefficient of Thermal Expansion or Volume Expansion Factor (dimensionless)

$T_{m}$ : Ambient Temperature of Brine-Density Measurement $\left({ }^{\circ} \mathrm{F}\right)$

$T_{s}$: Standard Reference Temperature $\left(70^{\circ} \mathrm{F}\right)$

Output(s)

$\rho_{s}$: Density of Brine at Standard Reference Temperature $(\mathrm{lbm} / \mathrm{gal})$

Formula(s)

$$ \rho_{s}=\rho_{m}\left[1+C_{t e}\left(T_{m}-T_{s}\right)\right] $$
