ROC Permanent Downhole GaugesCable termination (field-pressure testable)PCB/hybridMechanical arrangement, including sealsPressure/temperature quartz transducer


HPHT Environments: ROC Permanent Downhole GaugeQuartz sensor-based design High accuracy (0.02% FS) High resolution (<0.01psi/sec) 30,000 psi / 200°C (390°F) Hybrid micro circuit design Smaller footprint Improved vibration resistance Increased reliability Design qualification completed System reliability > 90% @ 5 yrs @ 180°C 3”


ROC Hybrid AdvantagesLong-term reliability at extreme temperatures Excellent heat dissipation over traditional downhole electronics Improved thermal shock resistance Improved physical shock and vibration resistance Compact size


Qualification Testing CompletedElectronic Circuit Testing Verified functionality from 0°C to 220°C Telemetry Performance Determined telemetry performance at 35,000ft cable length Noise Tolerance Testing Confirmed telemetry performance in high noise environment HALT Testing Lifetime testing including combined environment testing Weld and Seal Testing Testing of seal performance at elevated pressure and temperature QALT Testing Determine lifetime estimates as a function of temperature
