BGES provides reliable permanent subsurface pressure and temperature monitoring options for optimal reservoir and/or water zone measurements.
The permanent monitoring system is installed in the well as an integral part of the completion. Its durable components are able to withstand extreme temperature conditions for long-term applications.
Downhole sensors include:
Piezo – cost-effective and rugged Quartz – high accuracy Piezometer – high temperature Thermocouple – high temperature multi-point RTD – precise temperature monitoring
Appl ica t ions Pressure/temperature monitoring for SAGD
plants (Injector / Producer Monitoring) CO2 storage caverns or other types of storage
wells Coalbed methane for fluid level monitoring and
pump protection Observation, production or injection wells Aquifer monitoring
Various high-temp monitoring applications — up to 6 points of temp monitoring with a single 0.25” line
Features & Benef i ts Permanent real-time downhole monitoring system can transmit 24x7 real-time pressure and temperature data to your desktop via DCS, SCADA
