Abstract

The invention is related methods for nuclear magnetic resonance measurements; the methods include the steps of applying a first static magnetic field to polarize the sample; radiating a radio frequency pulse onto the sample. Subsequently, applying a second magnetic field such that when combined with the first static magnetic field; a third static magnetic field is produced. Finally, during the application of the second static magnetic field or after removing it, the NMR signal emitted by the sample is measured. Finally, the methods can be used for making nuclear magnetic resonance measurements in wells.
