Abstract

Summary

In 2015, the Valhall field benefited from a rejuvenated multi-component seismic processing sequence from a large OBC survey (permanent LoFS array supplemented with extra-seabed cables) covering the full field. These new high-resolution compressional and converted reflectivity pictures were decisive in understanding the structural framework, the distribution of sands units and the presence of gas in the overburden. Combining the updated overburden description with an extensive effort of reviewing the wells history will reduce risks for future wells and P&A, while demonstrating the value of long-term seismic strategy and integrated multi-disciplinary approach.
