Guardian: real-time seismic processing

Passive microseismic monitoring is used to improve safety and decision-making during drilling, tunneling and subsurface injections.

For those applications, a fast response time between data acquisition and action is required, with a typical maximum of two hours delay.

OCTIO Environmental is using Guardian as an integrated solution to process seismic data and provides the information required for decision-making within that time range.

• Noise removal algorithms
• Microseismic event detection and location
• Alarm handling, including alarm push on smartphones
• Integration of well measurements and environmental information
• History line for navigation through microseismic events
• Integrated visualizaton of all data types
• Log interface for easy communication between interested parties

Microseismic events recorded during 240 hours at the Oseberg oilfield.
