Compensation of magnetic influence in a MWD system |
| abstract |
The present disclosure provides a downhole tool that includes a magnetometer and a nuclear magnetic resonance (NMR) sensor. One or more compensating magnets are provided on the tool to cancel or offset the effect of the magnetic field of the magnets of the NMR sensor on the magnetometer measurements made during drilling of a wellbore. The compensating magnets may have the same magnetic field characteristics as the sensor magnets and may be made of the same material. |
