ProTherma™ Geothermal PTS Tool
Provides production logging and formation measurements in either surface readout or memory mode, in high pressure and ultra-high temperature environments
Applications
- Geothermal and steam injection well surveys
- Monitor well performance
- Reservoir management
Features and Benefits
- Operating temperatures up to 662°F (350°C) makes it suitable for geothermal and high-temperature wells
- Provides comprehensive data by measuring pressure, temperature, flow rate, formation gamma ray, and casing collars, essential for detailed well analysis
- Capable of operating in both memory and surface readout mode, offering operational flexibility
Tool Description
The Weatherford ProTherma geothermal PTS tool is a production logging tool that provides pressure (using precision quartz pressure sensor) temperature, flow rate, gamma ray, and casing collar measurements in either memory or surface readout mode in ultra-high-temperature environments.
