Focused Seismic Monitoring (FSM) is to monitor the reservoir in smaller, more focused areas than conventional time-lapse surface seismic would normally cover (Thompson, 2008). During 2008 a FSM field trial was carried out with the aim of achieving an insight into installation, acquisition and imaging procedures such that time-lapse seismic could be imaged in ‘near time’. Two 5km long multi-component seismic array cables, each containing 100 seismic sensor stations, were installed on the Snorre field and were connected to the Snorre A platform via an existing fibre tail. A data interrogation unit and data QC unit were installed on the platform and networked to a dedicated onshore support centre (OSC) and imaging cluster.

The pilot demonstrated ‘real time’ data transfer and quality control and imaging in ‘near time’.
