Summary:
We present a case study of fast turn-around processing and analysis of time-lapse seismic data
acquired using the Life of Field Seismic (LoFS) permanent receiver array. We combine a
small computer cluster, a broad band connection to the offshore facilities and script-base
processing software into an automated workflow from acquisition to interpretation. This
results in delivery of time-lapse processed volumes to the interpreters within a week after last
shot. By automating the generation of time-lapse difference volumes and extractions, we
deliver fast-track interpretation of the main time-lapse effects within hours of data arrival in
Stavanger. These main time-lapse effects are captured in graphic files, which are all
automatically linked in HTML documentation. This automation and standardization has
allowed moving the main workload of the geophysicist from of data manipulation to
interpretation and integration of the collected data.
