    摘要: A method and apparatus for estimating a rock strength profile of a formation is disclosed. A tool having a testing surface is conveyed into a wellbore in the formation. The testing surface is propelled to impact the formation at a plurality of depths in the wellbore. A measurement of hardness of the formation is obtained from a rebound of the testing surface from the formation at the plurality of depths. The rock strength profile of the formation is estimated using the obtained measurements of hardness at the plurality of depths. A parameter for drilling the wellbore can be affected using the estimated rock strength profile.

    摘要: 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.
