Average reservoir pressure over the drainage volume :
p_r = \frac{1}{V_e} \iint_{A_e} p(x,y,z) dV |
For the Steady State Radial Flow in finite reservoir the relationship between Boundary-average formation pressure and Drainarea formation pressure is going to be:
p_r = p_i - \frac{q_t}{4 \pi \sigma} |
|
For the Pseudo-Steady State Radial Flow in finite reservoir the relationship between Boundary-average formation pressure and Drainarea formation pressure is going to be:
p_r(t)= p_e(t) - 0.75 \cdot \frac{q_t}{2 \pi \sigma} |
