Natural Gamma Neutron Logging Tool 2009 All Rights Reserved-Century Wireline Services
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.
