The   Natural   Gamma,   Neutron   logging   tool   is   designed   for   open   and cased   hole   use.   In   open   holes   the   neutron   log   may   be   converted   to porosity   units   based   on   a   limestone,   sandstone   or   dolomite   matrix.   The tools   small   diameter   makes   it   useful   for   logging   Natural   Gamma   and Neutron   through   drill   rods   in   cases   where   the   hole   is   to   unstable   to   be logged   open   hole.   Natural   Gamma,   X-Y   Inclinometers   and Azimuth   are optional.
