IntelleX™ Ultra-Fast Gauge Tool
Monitors rapid pressure changes during downhole explosive operations
Applications
- Well stimulation
- Perforating (dynamic/static underbalance monitoring or perforation efficiency)
Features and Benefits
- Ultra-Fast Sampling: Able to switch to high-speed sampling within 100 microseconds, enabling precise capture of rapid pressure transients, crucial for analyzing explosive operations
- Flexibility: Programmable with various trigger events, enabling customization for different applications and optimizing data collection
- Versatility: Combines slow- and high-speed sampling capabilities, making it suitable for a wide range of downhole applications, including well stimulation and perforation monitoring
Tool Description
The Weatherford IntelleX ultra-fast gauge tool is a battery-powered instrument designed to record pressure, temperature, and acceleration data at extremely high sampling rates in order to capture pressure transient events typical of downhole perforating operations.
