Ratio of current Water injection rate to current Liquid production rate :
{\rm PRR} = \frac{q^{\downarrow}_{WI}}{q^{\uparrow}_L} |
It is normally calculated for the whole field or its sector and represents one of the key Production Analysis metrics.
Unlike VRR, the PRR does not have a direct correlation with reservoir pressure maintenance and is mostly used as engineering tool for a trackable target in field operations.
Most Reservoir Engineers make their analysis in VRR categories and then translate them into PRR so that Production Technologists can follow up.
