UHT Pulsed Neutron Tool – Maximum Performance in Extreme Temperatures

The demands on modern logging technologies continue to increase—especially under extreme temperature conditions. The UHT (Ultra High Temperature) Pulsed Neutron Tool by PNN Plus sets a new benchmark by combining durability, precision, and operational simplicity.

Proven Success in High-Temperature Field Operations

A recent deployment by our partner clearly demonstrates the tool’s exceptional capabilities:
Operating continuously for 6 hours at 200°C, the tool maintained stable and reliable performance throughout.

The recorded data highlights:

  • The internal temperature of the monoblock increases only gradually
  • Even after 6 hours, the internal temperature approaches but does not exceed 100°C
  • Effective thermal insulation protects sensitive components

Additionally, the diagrams show the accurate response of the probe to downhole conditions, ensuring high-quality data acquisition.

Simplicity as the Key to Reliability

Unlike many complex solutions on the market, the UHT tool is built around a streamlined and robust design philosophy.

Key Advantages of the Simple Design

  • Increased reliability under extreme conditions
  • Reduced risk of failure
  • Easier maintenance and handling
  • Elimination of unnecessary components without compromising data quality

Field experience confirms:
Simplicity outperforms complexity, especially in high-temperature environments.

Efficient Operation and Handling

The tool is designed with practical usability in mind:

  • Rugged and easy to operate
  • No need for complicated handling procedures
  • Ideal for demanding field environments

Compared to competing systems requiring highly specialized personnel and complex preparation, the UHT tool offers a significantly more efficient solution.

Integration with Advanced Software and Analysis

The full potential of the tool is realized through integration with modern systems:
