nj: any drilling fluid, usually oil-base or invertemulsion muds, whose continuous phase dose not co9nduct electricity, e.g.oil. The spontaneous potenial and normal resistivity can not be logged, although such other logs as the induction, acoustic velocity etc

n: schlumberger wireline tool that used for microinduction sensor to measure the variations of formation conductivity. Applications include determination of stuctural dip when non-conductive mud is in use and borehole geometry.
