ABSTRACT:
Saturation pulse sequences are designed to ensure complete saturation of nuclear spins for dual wait time measurements and saturation recovery measurements in the case of axial motion of a downhole NMR logging tool. Frequency and/or phase modulation may be used. An auxiliary saturation coil may be used.
