1. An apparatus for use in drilling an oilfield wellbore, comprising:

  • (a) a drill disposed on a distal end of a drillstring;

    (b) a plurality of sensors disposed in the drillstring, each said sensor making measurements during the drilling of the wellbore relating to a parameter of interest;

    (c) a processor adapted to process the measurements for creating answers indicative of the measured parameter of interest; and

    (d) a downhole analyzer including a neural network operatively associated with the sensors and the processor for predicting behavior of the drillstring.
