UCS = 6105 e(M ´ 1.31e^–7)

6105 is in psi.

1.31 is in 1/psi.

M is P-wave modulus in psi.

This is an empirical formula based on core data correlated to well logs in the Browse Basin, northwest Australia. The sandstones were well lithified and consolidated with core porosity ranging between 5 and 12 percent, resulting in UCS > 12,000 psi.
