  • Method and apparatus for prediction control in drilling dynamics using neural networks
    Patent number: 6732052
    Abstract: The present invention provides a drilling system that utilizes a neural network for predictive control of drilling operations. A downhole processor controls the operation of the various devices in a bottom hole assembly to effect changes to drilling parameters and drilling direction to autonomously optimize the drilling effectiveness. The neural network iteratively updates a prediction model of the drilling operations and provides recommendations for drilling corrections to a drilling operator.
    Type: Grant
    Filed: September 28, 2001
    Date of Patent: May 4, 2004
    Assignee: Baker Hughes Incorporated
    Inventors: Robert P. Macdonald, Volker Krueger, Vladimir Dubinsky, John D. MacPherson, Dmitriy Dashevskiy

  • Drilling system with integrated bottom hole assembly
    Patent number: 6206108
    Abstract: The present invention provides a drilling system that utilizes an integrated bottom hole assembly. The bottom hole assembly contains sensors for determining the health of the bottom hole assembly, borehole condition, formation evaluation characteristics, drilling fluid physical and chemical properties, bed boundary conditions around and in front of the drill bit, seismic maps and the desired drilling parameters that include the weight on bit, drill bit speed and the fluid flow rate. A downhole processor controls the operation of the various devices in the bottom hole assembly to effect changes to the drilling parameters and the drilling direction to optimize the drilling effectiveness.
