High Resolution Interpretation of Broad Bandwidth 3D Seismic Data for Shallow Geohazards

Safe drilling operations require robust and timely identification of geohazards. Broad bandwidth 3D seismic data can help achieve this if appropriate interpretation is performed. By exploiting the recent developments in global interpretation algorithms and utilising quantitative interpretation techniques the benefits of broad bandwidth 3D seismic can be more fully leveraged. To this end the use of global interpretation algorithms is demonstrated on a broad bandwidth 3D seismic dataset and is used to perform stratigraphically consistent identification of geohazards. This analysis is complimented by a fault identification attribute that uses dip information and cross-plotting of AVA/AVO attributes to automatically map potential geohazards. Much of this analysis can be automated enabling more time to be spent analysing identified geohazards. Overall, our motivation for sharing this work is to keep shallow geohazard identification techniques up-to-date.
