Introducing our innovative permanent reservoir monitoring system. The SageWatch Subsurface Surveillance System provides real-time pressure and temperature data for many applications. Its unique design allows for simultaneous monitoring of unlimited points within a single wellbore with any casing size.
The SageWatch™ Subsurface Surveillance System is a proven method for gathering long and short term data for a wide base of applications. Through a better understanding of reservoir parameters, connectivity, field drainage, and stimulation processes, SageWatch™ creates high-level value through a better understanding of reservoir parameters.
Installed Outside the Casing
It can monitor reservoir activity only, internal casing activity only, or a combination of the two. It is cemented into place to provide isolation between zones.
Applications have progressed beyond monitor-only wells. The system can also be installed for completion wells and those monitored with the real-time downhole P/T gauges in place. Multiple monitoring points can also be ported to read internal pressures at any point along the wellbore.
It is installed permanently behind pipe and conveyed as an integral part of the casing string. All communication and power lines run along the outside of the casing to the surface. Once cemented into place, the P/T gauges are connected to the reservoir through perforations allowing for continuos real-time, undisturbed data.
Benefits of this system include:
- Reservoir definition, establishing true perm, identifying crossflow
- Well spacing optimization
- Verifying injection pressures, migration
- Identification of unusual geology
- Modeling verification and calibration
- Offset fracturing
- Downhole fracture monitoring
- Ability to run in conjunction with fiber optics
Installed Inside the Casing
It can monitor individual sections within the wellbore. Isolation is achieved through hydraulic or swellable packers.
Even during drilling, stimulation, and production, data will be collected. Each individual monitoring point along the wellbore is isolated giving true individual points of data. Powered from the surface, this method collects data which can be accessed locally or transmitted wirelessly via any typical field SCADA system.
Additional benefits of this system include:
- Can be run in small or large casing
- Can take advantage of old vertical wells
- Can be installed above areas of collapsed casing
- Provides data to monitor close proximity new wells
