Elastic capacity of aquifer to expand into oil reservoir or gas reservoir due to pressure depletion:
(1) | B = \frac{\theta}{2\pi} \cdot A_e \cdot h_a \cdot \phi_a \cdot c_t |
where
\theta | Central Angle of net pay area ↔ aquifer contact |
A_e = \pi \, r_e^2 | net pay area |
h_a | aquifer effective thickness |
\phi_a | aquifer porosity |
c_t=c_r +c_w | aquifer total compressibility |
c_r | aquifer pore compressibility |
c_w | aquifer water compressibility |
(2) | B = 1.119 \cdot A_e \cdot h_a \cdot \phi_a \cdot c_t |
where
