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.
