CTN™ Compensated Thermal Neutron Sensor
The CTN™ sensor provides accurate porosity, fluid type and lithology information for real-time decision making and wireline replacement applications. Porosity is computed from the near/far detector count rate ratio with robust environmental corrections applied for hole size, standoff, mud weight, mud salinity, formation salinity, pressure and temperature. When combined with the ALD™ azimuthal lithodensity or BAT™ bi-modal acoustic sensors, the CTN tool logs can also be used to detect and evaluate gas-bearing formations, and to determine lithology and porosity in complex mineralogy formations.
Applications
- Porosity measurement
- Gas detection
- Reservoir fluid typing
- Lithology evaluation
- Real-time evaluation
- Wireline replacement
SOLAR™: this sensor also exists in the high temperature/high pressure version. Please refer to the SOLAR datasheet for exact specifications.
