Features VIGOR Battery Control Unit 43C (BCU43C) is developed for power supply to complete the logging when the logging instrument is conveyed by slick line or by tubing for production logging. The different BCU43C cartridges have different capacities, and will provide power for different logging instrument string with different requirement for current, and the logging time will also have differences. Everytime when use the BCU43C, operator should record the current value and working time, and evaluate the rest capacity to see if it could satisfy the next logging operation before RIH.
