GROUND WATER BRANCH TECHNICAL MEMORANDUM NO. 72.04

Subject:  PUBLICATIONS - Application of geophysical logging to
                         ground-water studies in southern
                         Saskatchewan

The subject report is a brief summary of the logging methods in
general use in ground-water investigations.  Figures 2 and 3 of
this report are especially valuable because they compare response
of caliper, gamma ray, spontaneous potential, single and multiple
point resistivity, neutron, and gamma-gamma logs in the same
holes.  The color coding which carries the lithology across the
illustration makes the response of the various logs to lithologic
changes especially easy to follow.

The Borehole Geophysics research group in Denver and the Ground
Water Branch have a few additional copies of this report, which
are available on request.
