Multi Drop Gauge Systems
RFT™ Downhole Gauge Systems (300 °C Rated) RFT™ (Resonant Frequency Transducer) gauges are qualified for continuous operation up to 300 °C, providing high-accuracy pressure and temperature measurements for geothermal reservoir characterization, injectivity testing, production diagnostics, and long-term monitoring.
Key capabilities include:
Continuous high-temperature operation up to 300 °C
High-resolution pressure and temperature measurement with excellent long-term stability
Minimal drift in high-pressure, high-temperature environments
Proven performance in permanent geothermal installations
Seamless integration with distributed sensing and surface acquisition systems
High Denisty Temperature Monitoring
PEP™ (Precise Engineered Polymer) systems are high-density, conductor-based thermocouple assemblies designed for continuous temperature monitoring up to 300 °C in extreme downhole environments.
PEP™ systems are used extensively in high-temperature reservoir monitoring applications, providing reliable, depth-distributed temperature measurements where fiber-based or electronic sensing alone may be insufficient or where redundancy is required.
Key advantages include:
High-density temperature measurement along the wellbore
Continuous operation up to 300 °C
Robust polymer encapsulation engineered for thermal cycling and mechanical loading
Proven reliability in long-term, permanent geothermal installations
Complementary deployment alongside DFOS and RFT™ systems
PEP™ thermocouple systems provide precise thermal profiling for reservoir performance evaluation, injectivity monitoring, heat sweep analysis, and completion diagnostics.
Acquisition Systems & Advanced Data Processing
Distributed Temperature Sensing (DTS) Thermal profiling for inflow/outflow identification, heat-sweep monitoring, and reservoir performance evaluation.
Distributed Acoustic Sensing (DAS) Real-time insight into flow dynamics, fracture activity, and mechanical integrity along the entire wellbore.
Distributed Acoustic Sensing (DSS) Real-time insight into atrina nd mechanical dynamics, fracture activity, and mechanical integrity along the entire wellbore.
PSSP-AI™ (Precise Signal Stream Platform – AI)
PSSP-AI™ is a cutting-edge, physics-based machine-learning platform delivering advanced, real-time quantitative flow intelligence at 1 m resolution along the full wellbore. The platform provides phase-specific flow characterization (water and gas), velocity profile indexing, and continuous insight into downhole mechanical and hydraulic behavior through real-time completions monitoring—presented in an easily digestible operational format.
