Tool Lifetime DataThis invaluable data is internally logged by the NDM for both sensor lifetime and the last downhole run.

When connected to the Internet, the Internet, downloaded data is automatically added to your company’s private “HUB" account. Full historical tool records saved in the cloud available from cloud available from any web browser.

NDM records and accumulates downhole environmental data into segmented temperature ranges. In this way the exact temperature exposure for the tools are can be fully understood and documented.

Shock and vibration exposure are also segmented into increasing severity buckets. This allows users to know how much

stress the tool has experienced laterally, axially, and torsionally.

As NDM is all of your MWD Electronics - life time maintenance management becomes easy.

Environmental Logging

NDM has unprecedented logging capabilities with a large memory fast dump.
