Continuous seismic surveillance of Valhall Field

Abstract

Since the permanent seismic system was installed over Valhall Field five years ago, 11 surveys have been collected—each designed, acquired, and recorded with a high repeatability and efficiency. The time-lapse (4D) data have been processed using a consistent and fast workflow that generates results within weeks. The fast turnaround ensures that information is relevant and has maximum impact on short- and long-term management decisions.
