Reservoir Monitoring – An Overview
Monitoring using repeat seismic surveys can measure changes in reservoir pressure and fluid content, identify flow barriers and untapped reserves, and help to optimise hydrocarbon recovery schemes including the placement of injection and production wells.
The technique, known as “4D” or “time-lapse” seismic, involves acquiring several 3D seismic surveys at different times, ideally beginning before production has started and at intervals thereafter. Differences in the seismic response between surveys can indicate changes in the reservoir.
These differences can be extremely subtle, and are easily masked by differences between surveys caused by other factors such as differences in receiver position. Permanently installed seabed arrays help to minimise these spurious differences to more accurately measure changes in seismic response. Unlike towed-streamer solutions,
seabed arrays record the full multi-component seismic wavefield, which can reveal considerably more about a reservoir.
The Fosar system from Stingray is a highly efficient and cost-effective seismic PRM solution that reduces system uncertainties, minimises installation and operational risk, and facilitates seismic on demand for enhanced reservoir management.
