| 1 | Assess flowrate across the pulsing unit (from QZI log),bottom-hole pressure and formation pressure . |
| Assuming that recent PLT is available, both flowing and shut-in survey |
| 2 | Calculate productivity index |
| LaTeX Math Block |

| J = \frac{q_t}{p_e - p_{wf}} |

| 3 | Calculate pulsing flowrate across target formation during PCT |
| LaTeX Math Block |
|---|
| q_t(t) = J \cdot (p_e - p_{wf}(t)) |
| Assuming that formation pressure did not change much between PLT and PCT survey |
