One of the Steady-State Diagnostics methods based on plotting pressure integral vs cumulatives
It shows unit slope for SS flow regime:
P(t) = J^{-1} Q(t) |
where
constant productivity index |
Although it is equally applicable to both producers and injectors, due to pressure data availability in practical cases the hall plot sought the most of its applications for water injectors.
