Memory battery holder (MBH) for slickline motor power and memory tools
The type MBH018 Memory Battery Holder houses a motor battery pack used, for example, with the Multifinger Imaging Tool or memory Diverter Basket Tool. This listing focuses on the Memory Battery Holder as a downhole power module for memory-mode and motorized tool combinations where surface power cannot be provided.
Operating principle from the existing copy: data from the logging sensors is transmitted via the Tool Bus to the memory tool at the top of the string and stored in nonvolatile flash memory chips under the control of a downhole processor. The tool can support standard CNPS memory tools and record readings from every sensor at up to 10 sets per second.
Published MBH specification figures on this page include pressure (max) 105 MPa, temperature (max) 150°C, lithium chloride battery pack, open-circuit voltage 19.5 VDC, capacity 6 amp·hr, length 495 mm, diameter 43 mm, weight 3.6 kg, corrosion-resistant material throughout, end threads 13/16″ 12 UN2A GO (top/bottom), and end connectors Fischer triax / single-conductor 4 mm socket. Application stated: to power tool motors on slickline or where motor power cannot be provided from surface; interfacing with standard CNPS Memory Telemetry Tools.
Key applications
- Powering tool motors on slickline when surface power is unavailable
- Memory Battery Holder supply for Multifinger Imaging Tool strings
- Memory Diverter Basket Tool and related memory telemetry combinations
- Recording sensor sets via the Tool Bus into nonvolatile flash memory
What to confirm with CNPS
- MBH018 (or alternate) fit to your memory / motorized tool string
- Pressure / temperature envelope versus the published MBH figures
- Connector and thread compatibility with your telemetry tools
