# Estimating volume of steam injection (steam-drive)

## Input(s)

$$C_{w}$$: Specific Heat Capacity of Water (BTU/LBM F)

$$T_{s b}$$: Temperature of Steam at Boiler Outlet $$\left({ }^{\circ} \mathrm{F}\right)$$

$$T_{a}$$: Ambient Temperature $$\left({ }^{\circ} \mathrm{F}\right)$$

$$f_{s b}$$: Fraction of Steam at Boiler Outlet (fraction)

$$T_{i d h}$$: Injection Temperature Down Hole $$\left({ }^{\circ} \mathrm{F}\right)$$

$$T_{i}$$: Injection Temperature $$\left({ }^{\circ} \mathrm{F}\right)$$

$$f_{s d h}$$: Fraction of Steam Down Hole (fraction)

$$L_{v d h}$$: Latent Heat of Vaporization Down Hole (BTU/lbm)

$$L_{v b}$$: Latent Heat of Vaporization at Boiler Outlet (BTU/lbm)

## Output(s)

Ws, eq: Volume of Steam injected, as Water Equivalent (BBL/d)

## Formula(s)

$\text { Ws, eq }=\left(2.853 * 10^{-6}\right) * \frac{\mathrm{C}_{\mathrm{w}} *\left(\mathrm{~T}_{\mathrm{sb}}-\mathrm{T}_{\mathrm{a}}\right)+\mathrm{f}_{\mathrm{sb}} * \mathrm{~L}_{\mathrm{vb}}}{\mathrm{C}_{\mathrm{w}} *\left(\mathrm{~T}_{\mathrm{idh}}-\mathrm{T}_{\mathrm{i}}\right)+\mathrm{f}_{\mathrm{sdh}} * \mathrm{~L}_{\mathrm{vdh}}}$
