Abstract
Apparatus and method of conducting a drilling operation are provided. One embodiment of the method includes drilling a borehole, predicting a value of a first parameter relating to the drilling of the borehole 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 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.
