Metris Extreme
HPHT permanent pressure and temperature gauge
Overview
Metris Extreme gauges are available in bottom-gauge (lower image) and multidrop (upper image) variants.
Applications
The gauges provide continuous PT measurements. Acquired data are used for
- long-term production, injection, and reservoir monitoring in real time
- production allocation and management
- production and injection optimization
- well productivity, pressure transient, and decline analysis
- workover and intervention planning
- improved field development via identification of interwell connectivity and optimization of offset well placement and completion design
- reservoir model improvement and validation
- artificial lift optimization
- hydraulic fracture monitoring.
The ability to multidrop these compact gauges on one monoconductor cable simplifies intelligent completion deployment.
Benefits
Enabling real-time evaluation and prompt corrective actions for enhanced well production
Metris Extreme gauges use quartz sensors for high-quality measurements in the tubing or annulus. Robust electronic technology and stringent qualification procedures ensure an extended lifetime and flawless performance.
The telemetry used by the gauge and surface acquisition unit is immune to external electrical noise and electromagnetic field interference (e.g., from ESP power cables or motor drives). Among other advantages, it enables multidropping up to 8 dual-sensor gauges (i.e., 16 sensors) on a single monoconductor cable and eliminates limitations on the distance between gauges.
Features
For extra reliability, the gauges are equipped with Intellitite™ downhole dual-seal dry-mate connectors. Incorporating a retainer system and two fully redundant metal-to-metal seals, this premium connector is fully pressure testable using a microleak detection system. The lower connection is V0-qualified per ISO 14998 and the gauge metallurgy is H2S resistant per NACE MR0175/ISO 15156.
FAQs
What makes Metris Extreme gauges a superior product?
These permanent gauges are engineered to deliver stable PT
measurements at downhole conditions, a quality that is essential
for long-term reservoir and production monitoring. Performance is
validated in a controlled test cell, where drift stability is measured at
simulated reservoir PT conditions. Every gauge is calibrated in-house
at an SLB manufacturing center to maximize performance.
The gauges are also subjected to power on-off cycles and temperature cycling to simulate the most demanding operating conditions. They are qualified for a lifetime in excess of 20 years at maximum pressure and up to 400 degF. Repeated shock and vibration testing at rigorous levels ensures that they meet the environmental qualifications for production and injection wells. Qualifications meet or exceed the Advanced Well Equipment Standards (AWES) recommended practice for the qualification of downhole instrumentation and sensors. Metris Extreme gauges transmit 32 system health tags to surface at regular intervals for diagnostic and prognostic system health monitoring.

How can you protect these gauges during deployment and long-term production?
Our solid gauge mandrel provides a protective recess for Metris system gauges. It is available in various grades of metal to ensure characteristics equivalent or superior to the tubing, and it can be installed in sweet to severely corrosive environments.
Mandrels are rated for various working pressures according to tubing weight and material grade. They have no inherent weak points or highly stressed areas because they are machined from a single block (billet) with no weld seams. These solid gauge mandrels are designed and manufactured to API Spec 5CT for collapse pressures, burst pressures, tensile strengths, and drift. They are custom cut with premium connections; tong space and thread recut lengths are provided as requested.
