where is running through wells with formation pressure tests and rates
For the steady state flow in finite reservoir the relationship between Boundary-average formation pressure and Field-average formation pressure is going to be:
p_r = p_i + \frac{q_t}{2 \pi \sigma} \Bigg[ \ln \frac{r_e}{r_w} -0.5 \Bigg] |
