Cumulative heat injected for steam drive - Myhill and Stegemeier

Input(s)

$w_{i}$: Mass Rate of Injection of Steam into Reservoir (lb/d)

$c_{w}$: Average Specific Heat (BTU/lb K)

$\Delta \mathrm{T}$: Temperature Differential $(\mathrm{K})$

$f_{s d h}$: Steam Quality (fraction)

$L_{v d h}$: Latent Heat of Steam (BTU/lb)

Output(s)

$Q_{i}$: Heat Injection Rate (BTU/d)

Formula(s)

$$ \mathrm{Q}_{\mathrm{i}}=\mathrm{w}_{\mathrm{i}} *\left(\mathrm{c}_{\mathrm{w}} * \Delta \mathrm{T}+\mathrm{f}_{\mathrm{sdh}} * \mathrm{~L}_{\mathrm{vdh}}\right) $$
