Sondenerneuerung

Sondenerneuerung refers to the process of modernizing or renewing the acoustic logging tool (so-called “sonde” in German) used in the exploration for petroleum and natural gas deposits. This tool is deployed in a borehole to collect data about the properties of the surrounding rock formations.

The basic principles of sound wave generation and analysis have remained the same, but the Sondenerneuerung involves upgrades to the tool's electronic and mechanical systems, as well as its measurement technology. This upgrade aims to ensure that the tool continues to provide accurate and reliable data, contributing to more efficient and effective exploration processes.

In this context, additive manufacturing techniques have been applied during Sondenerneuerung to produce replacement parts for critical components of the logging tool. This manufacturing approach enables the creation of parts with complex geometries and specific properties tailored to meet the demanding requirements of the tool's operation.

Furthermore, the Sondenerneuerung may involve testing and validation procedures to ensure that the modified sonde adheres to standard protocols and requirements. This involves reviewing specifications, testing measurement data generated by the tool, and comparing it with expected results or verified empirical data from previous loggings.

By introducing these advances, petroleum and natural gas exploration and production much more information about rock formations than before and enable fracturing drilling and crack determination.
