The historical Production rate / Injection rate from/to the target pay maybe not accurate both due to metrological inaccuracy and thief water production/injection.
The ratio between the adjusted and historical Production rate / Injection rates called Production/Injection Adjustments Coefficients:
\displaystyle \alpha^{\uparrow}_O = \frac{q^{\uparrow}_{O, \ \rm adj}}{q^{\uparrow}_{O, \ \rm hist}} | Oil production rate adjustment coefficient |
\displaystyle \alpha^{\uparrow}_G = \frac{q^{\uparrow}_{G, \ \rm adj}}{q^{\uparrow}_{G, \ \rm hist}} | Gas production rate adjustment coefficient |
\displaystyle \alpha^{\uparrow}_W = \frac{q^{\uparrow}_{W, \ \rm adj}}{q^{\uparrow}_{W, \ \rm hist}} | Water production rate adjustment coefficient |
\displaystyle \alpha^{\downarrow}_G = \frac{q^{\downarrow}_{G, \ \rm adj}}{q^{\downarrow}_{G, \ \rm hist}} | Gas injection rate adjustment coefficient |
\displaystyle \alpha^{\downarrow}_W = \frac{q^{\downarrow}_{W, \ \rm adj}}{q^{\downarrow}_{W, \ \rm hist}} | Water injection rate adjustment coefficient |
