First Claim
1. A method of conducting a drilling operation, comprising:
- drilling a borehole;
predicting a value of a first parameter relating to the drilling of the wellbore using a Geomechanical Model;
estimating a value of a second parameter from measurements taken by a sensor;
updating the Geomechanical Model based at least in part on the estimated value of the second parameter;
predicting in real time a second value of the first parameter using the updated Geomechanical Model; and
altering a drilling parameter for drilling the borehole based on the predicted second value of the first parameter.
