Abstract
The disclosure relates to a well logging method which is capable of providing an indication of salinity and water fraction of the production fluid of a borehole. This indication of borehole parameters may be obtained through the use of a conventional gamma ray logging system that detects gamma rays produced by isotopes created from neutron activation of oxygen, sodium, and chlorine that may be present in the production fluid. A logging sonde is passed twice through a portion of interest in the borehole at two different logging speeds. The fluid velocity relative to the sonde may be determined using these two logging speeds and a displacement distance which reflects the time required for a detector associated with the sonde to reach fluid activated by neutrons produced by the sonde. From these measurements and knowledge of the flow cross-section and parameters of the sonde, the fraction of water in the production fluid and the salinity of the water may be determined for each portion of interest of the borehole.
