WellWatcher Permanent Monitoring Systems

Point and distributed measurements in real time

WellWatcher permanent monitoring systems integrate the most advanced permanent downhole measurement technology with surface acquisition and data communication systems to allow remote monitoring of wells and reservoirs in real time. Pressure, temperature, density, and flow rate data are transmitted to remote locations via satellite, the Internet, or cable.

The data provide long-term reservoir and production monitoring without the cost of well interventions, helping you optimize well productivity and hydrocarbon recovery by identifying trends throughout the producing life of your well or field.
