Abstract
Rate of penetration (ROP) measurement system () has sensor apparatus on a drill rig detecting drilling advancement. Sender () transmits to a receiver (), optionally via a reflector (). An electronic sub () can include the sender (), receiver () or reflector (). Reflector () reflects signals to the receiver (). Distance measurement or space mapping can use LIDAR/laser and MEMS mirror. Releasable attachment to the drill rig can be by magnet (). Atmospheric or barometric pressure can be detected and pressure change can be used to determine distance moved. WOB, RPM, torque and time rate of progress can be measured and combined with distance moved measurements to assess wear on a drill bit. Near real time ROP measurement can be calculated and displayed () and/or reported (). Drilling efficiency and premature drill wear or change in rock can be determined.
