Memory Production Logging

Memory Production Logging

Memory Logging Tools, which are available in CNPS Standard Memory or Ultrawire configurations, can be run on slickline or coiled tubing to acquire and store data from PL and Inspection tools.


A Memory section is programmed and downloaded using an IBM compatible Notebook Computer via an interface. Once powered by a high capacity Lithium battery within a separate battery holder (MBH), data is acquired and stored in accordance with a user defined ‘profile’. This controls the sensors logged and the sampling rate. CNPS MEMLOG software is supplied with all memory tools, providing a graphical interface for programming and downloading the tool, together with capabilities for merging memory tool data with depth-time files from the CNPS Depth-Time Recorder.



Data from the logging sensors is transmitted via the Tool Bus to the memory tool at the top of the string. Data is stored in nonvolatile flash memory chips under the control of a downhole processor. The tool can support all the standard CNPS memory tools and record readings from every sensor at up to 10 sets per second.
