Abstract
A method of predicting wellbore stability is provided and includes: creating a parameterized model of a wellbore in laminated formation, the parameterized model including a plurality of laminated formation and wellbore related parameters; considering measurement data to determine the laminated formation and wellbore related parameters; updating the parameterized model by adopting the determined laminated formation and wellbore related parameters; and applying the updated parameterized model to derive a solution of wellbore stability.
