Shell’s Experience with 4D Seismic Monitoring and new Directions

4D seismic monitoring has become a near standard practice within Shell for field <br>management. We find that conventional seismic survey techniques need to be updated <br>for improved seismic repeatability, which is the key to being able to see small field <br>production related changes. Seismic surveys with sparse sea-bed receivers is one way we <br>expect to get better, faster and affordable results whenever needed.
