This    three-coil    slim    hole    induction    tool    was designed       to       provide       conductivity       and converted   resistivity   logs   in   open   boreholes   or PVC/plastic    cased    holes    with    casing    sizes 5.08     cm     (2     in.)     or     greater.     The     probe measures   the   rock   conductivity   in   borings   and wells   within   a   zone   of   25.4   to   127   cm   (10   to   50 in.)   from   the   well,   but   is   not   sensitive   to   the borehole   fluid,   casing,   or   grouting   materials. The   tool   can   also   be   used   in   air   filled   holes   to measure      the      conductivity      response.      In addition,   the   tool   also   simultaneously   records natural   gamma   ray   in   API   units   or   CPS   for determination   of   clay   content   and   radioactivity measurements.
