9540 Dual Induction Laterolog 2009 All Rights Reserved-Century Wireline Services
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.
