AbstractAn Apparatus Is Used With A Drilling Assembly For Drilling A Borehole. The Drilling Assembly Has An Impact Device Linked To A Drill Head. The Impact Device Is Powered By A First Fluid Under A First Pressure To Impart A Percussive Force To The Drill Head. The Percussive Force Is A Function Of The First Pressure. A Thruster Of The Drilling Assembly Is Also Linked To The Drill Head. The Thruster Is Powered By A Second Fluid Under A Second Pressure To Impart A Thrust Force To The Drill Head. The Thrust Force Is A Function Of The Second Pressure. Additionally, A Rotator Of The Drilling Assembly Is Linked To The Drill Head. The Rotator Is Powered By A Third Fluid Under A Third Pressure To Impart A Torque To The Drill Head. The Torque Is A Function Of The Third Pressure.; The Apparatus Includes A First Pressure Sensor Communicating With The First Fluid To Output A First Electrical Signal That Is A Function Of The First Pressure. A Second Pressure Sensor Communicates With The Second Fluid To Output A Second Electrical Signal That Is A Function Of The Second Pressure. A Third Pressure Sensor Communicates With The Third Fluid To Output A Third Electrical Signal That Is A Function Of The Third Pressure. A Position Sensor Outputs A Fourth Electrical Signal That Is A Function Of Depth Of The Drill Head Relative To A Reference Location. A Device Monitors The First, Second, Third And Fourth Signals. The Device Produces Respective Graph Traces Of Functions Of The Percussive Force, The Thrust Force, The Torque And The Depth.
