[ Production Logging Tool ]


Excerpt

Сased-hole logging tool assessing the borehole production or injection flow profile: the amount of fluid going out to the reservoir or in the borehole via each perforation zone or tuning/casing leaks. 

The corresponding logging service is called PLT survey.


The tool includes multiple sensors to assess the flow velocity and fluid type and correlate the tool location with OH logs (see table below).
