where
water → oil displacement efficiency | |
sandface injection rate, assumed equal to sandface liquid production rate | |
reservoir porosity | |
cross-section area available for flow | |
reservoir thickness | |
reservoir width = reservoir length transversal to flow | |
in-situ fractional flow function | |
relative oil mobility | |
relative water mobility |
In many practical applications (for example, laboratory SCAL tests and reservoir proxy-modeling) one can assume constant porosity and reservoir width:

where
dimensionless time | |
dimensionless distance between injector and producer | |
reservoir length along -axis | |
mobile reservoir pore volume |
