Early detection and anti-collision system |
| abstract |
An apparatus mechanically connected to a drill bit can include a bottom hole assembly having an MWD system, magnetic sensors, and a short range communications system. The short range communications system can be in electrical connection with the magnetic sensors. A method can include supplying a bottom hole assembly that includes an MWD system. The MWD system can have navigation sensors and acceleration sensors, magnetic sensors, and a short range communications system. The bottom hole assembly can be mechanically connected to a drill bit and the magnetic sensors can be within 10 feet of the bit. The method further includes measuring a magnetic field with the magnetic sensors and communicating the measurement of the magnetic field from the magnetic sensors to the MWD system through the short range communications system. |
