Abstract
The present invention decreases the time needed between collection cycles of a NML tool located in a wellbore penetrating an earth formation by zeroing the effect of prior-in-time residual polarization via a surprising change in the operating parameters, viz., generating the next-in-time polarizing field with a slow-rising turn-on segment for scattering precessing components of residual polarization thereabout. Result: cyclic NML logging speed can be greatly improved.
