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 20):
A method for obtaining nuclear magnetic resonance (NMR) data in a wellbore, comprising:\n introducing an NMR tool into the wellbore, wherein the NMR tool comprises:\n an antenna assembly operable to generate a radio-frequency magnetic field; \n a magnet assembly operable to generate a static magnetic field; and \n a compensating assembly comprising at least one electromagnet; \n producing a static magnetic field using the magnet assembly; measuring well logging data via the NMR tool; moving the NMR tool through the wellbore; and reducing the effect of lateral motion of the antenna and magnet assemblies on the NMR data by operating the compensating assembly.
