The Multi-Parameter E-Log tool is a multi-parameter resistivity tool primarily used for water well logging and monitoring wells. The tool records ten different parameters simultaneously in one pass of the borehole. The ten parameters are the following: natural gamma, spontaneous potential, single point resistance, 16 in. normal resistivity, 64 in. normal resistivity, 48 in. lateral resistivity, fluid resistivity, temperature, delta temperature, slant angle (tilt) and azimuth (bearing). Slant angle, bearing, and natural gamma are optional.
