Fibre optic, seismic and sensor arrays, and carriers
Severn Subsea Technologies has many years experience of developing remote monitoring systems including:
Fibre optic sensing
Real time field management, bi-directional control and monitoring, fiber-optic systems capture and transmit distributed temperature profiles with fiber optics reliably, accurately, and in real time to identify the time, location, and reason for changes in flow.
Sensor Array Systems
Multiple tools can form an array for the monitoring of a particular area in real time, digital sensor array system obtains reservoir data across the sandface of subsea wells in real time to monitor and characterize flow profiles. Electromagnetic induction enables wireless communication and power transmissions between the upper and lower completions.
Long-term stable, accurate measurements. integrate the most advanced permanent downhole gauges with surface data communication to allow remote monitoring of wells and reservoirs in real time. Pressure, temperature, and flow rate data are transmitted to remote location via satellite, Internet, or cable.
Severn Subsea Technologies (SST) offers a range of multi-component seismic sondes for both short and long term deployment applications.
The seismic sondes use the latest digital technology presented the capability of producing seismic arrays with a full 200°C capability for extended deployment downhole. The type of sensor will depend upon the application but will typically range from geophones through to very sensitive, high temperature accelerometers.
Seismic Sensor Carriers
Severn Subsea Technologies also offers ruggedised carriers used to house and deploy fibre optic accelerometer based seismic sensing tool. The SST sensor sonde carrier enables safe and easy multi-station seismic array installations in well tubing or casing.
