Hello everyone,
I have a question. When we have a
Vertical Wellbore & Anisotropic conditions and rock is saturated.
Immediately after drilling, what would be excess pore pressure?

Would it be positive around the hole?
Why its not zero?
would it be negative?

Or its dependent on sign of mean strength increment Delta P?
Why would it be dependent on mean strength increment? whats the reason?
