Abstract:
Nuclear magnetic resonance (NMR) tools, logging systems, and methods for measuring NMR properties of earth formations in a region of interest are provided. The NMR tool includes an antenna assembly, a magnet assembly, a compensating assembly, and a motion sensor. The antenna assembly is operable to generate a radio-frequency magnetic field and the magnet assembly is operable to generate a static magnetic field. The motion sensor is operable to generate readings for lateral motion of the antenna and magnet assemblies. The compensating assembly contains at least one electromagnet and is operable to reduce variation of the static magnetic field in the region of interest due to the lateral motion during NMR measurements based on the readings for the lateral motion.

Claim (Index 29):
A logging system, comprising:\n a conveyance; and a nuclear magnetic resonance (NMR) tool for use in a wellbore and coupled to the conveyance, the NMR tool comprises:\n an antenna assembly comprising an antenna winding at least partially disposed around a soft magnetic core comprising an upper axial end opposite a lower axial end, the upper and lower axial ends are axially aligned by a common axis; \n a magnet assembly comprising an upper end magnet spaced apart from the upper axial end of the soft magnetic core and axially aligned with the common axis and a lower end magnet spaced apart from the lower axial end of the soft magnetic core and axially aligned with the common axis; and \n a compensating assembly comprising an upper electromagnet disposed between the upper end magnet and the upper axial end of the soft magnetic core and a lower electromagnet disposed between the lower end magnet and the lower axial end of the soft magnetic core, the upper and lower electromagnets are axially aligned with the common axis; \n wherein the antenna assembly and the magnet assembly produces a static magnetic field in a volume within a subterranean region; and \n wherein the compensating assembly reduces or increases the static magnetic field that has a changed field due to lateral motion of the antenna and magnet assemblies.
