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).Navigation tools 1 GR Gamma Ray 2 CCL Casing Colar Locator 3 INCL Trajectory Deviation Flow Rate Measuring & Flow Indicating tools 4 FBS Full-Bore Spinner 5 CFS Continuous Flow Spinner 6 ILS In-Line Spinner 7 HEX Thermal Anemometer 8 USF Ultrasonic Flowmeter 9 SNL Spectral Noise Log Borehole fluid hold-up tools 10 TEMP Fluid Temperature 11 PRES Fluid Pressure 12 RHORF Fluid Density 13 RHOUF Ultrasonic density 14 DIFP Pressure gradient 15 COND Fluid Conductivity 16 CAP Fluid Capacitance 17 IRG Infra-red Gas Hold-up Borehole cross-section tool 18 XYC XY Caliper Conveyance tools 19 RC-3 3-arm Roller Centralizer 20 RC-4 4-arm Roller Centralizer 21 BSС BowSpring Centralizer
