Abstract

Summary

We show here a novel velocity model building approach using the Beam-derived wavelet attributes through a 3D PSDM case study in the UK northern North Sea. There are several advantages by using the Beam-derived wavelet attributes to update the velocity model compared with the conventional method. The most important experience acquired from this project is the velocity model building lifecycle is significantly shortened without compromising the quality. Additionally, this Beam approach has its unique flexibility in pre-conditioning and post-processing seismic data, e.g. demultiples, as well as resolving local velocity anomalies. It is also demonstrated how the pre-BCU challenge was tackled in this project.
