Unmatched expertise in well intercepts

With over 300 well intercepts drilled over a four-decade track record of success globally, the WellSpotTM active magnetic ranging service from Halliburton achieves an industry high success rate.

The WellSpot system is used to precisely position wellbores when access to the target wellbore is not available. The WellSpot system uses a wireline receiver and excitation source. A current is injected into the formation and a distinct magnetic field is produced on the target well. This magnetic field is then analyzed by the receiver providing a distance and direction (magnetic/ gravity/gyro) to the target up to 200 ft (61 m) away.
