Formation permeability in transversal to vertical direction.
(1) |
k_h = \sqrt{k_x^2+k_y^2} |
|
(2) |
k_x = k_h \cdot \cos \alpha |
|
(3) |
k_x = k_h \cdot \sin \alpha |
|
(4) |
\tan \alpha = \frac{k_y}{k_x} |
|
For laterally isotropic reservoir :
(5) |
\tan \alpha = 1 \quad \Leftrightarrow \quad k_h = k_x = k_y |
