The 9540 tool is a multi-parameter resistivity tool primarily used for
oil/gas and water well logging. The tool records four different
parameters simultaneously in one pass of the borehole.
The four parameters are the following: spontaneous potential,
laterolog, deep and medium induction conductivity. The induction
curves are corrected for skin effect, and then converted to resistivity.
This tool is capable of recording a true resistivity (Rt) of the formation
with the deep induction having a 152.4 cm (60 in.) depth of
investigation.
