  • Mechanical specific energy drilling system
    Patent number: 8833487
    Abstract: A mechanical specific energy downhole drilling assembly having a bottomhole assembly including drill pipe and a drill bit, a weight on bit and torque sub for sensing torque, weight on bit and revolutions per minute of the drill bit; a command and control sub for receiving input from the weight on bit and torque sub for determining instantaneous mechanical specific energy of the downhole drilling assembly and an anti-stall tool responsive to real time mechanical specific energy information from the command and control sub to adjust the weight on the drill bit to maximize rate of penetration of the drill bit.
