Ideally balanced water + dead oil 1D waterflood model without gravity and capillary effects.

where
\displaystyle s= E_D = \frac{s_w - s_{wi}}{1-s_{wi}-s_{or}} | water → oil displacement efficiency |
q | sandface injection rate, assumed equal to sandface liquid production rate |
\phi(x) | reservoir porosity |
A(x) = h \, L_D | cross-section area available for flow |
h(x) | reservoir thickness |
L_D(x) | rerservoir width = reservoir length transversal to flow |
\displaystyle f = \frac{1}{1+M_{ro}/M_{rw}} | in-situ fractional flow function |
relative oil mobility | |
M_{wo} = k_{rw}(s_w)/\mu_w | relative water mobility |
