Problem

A vertical wellbore has encountered a fault plane at a depth of 4300 ft, which has a dip angle of 230; the cohesion and friction angle of the fault plane are 0.5 MPa and 250 respectively. The total vertical and horizontal (isotropic) stresses, at the point of interception, are 30 MPa and 15 MPa correspondingly. Ignoring the effect of wellbore stress redistribution, what is the maximum allowable mud weight in order to prevent fault reactivation?
