Fast Cycle Time Broadband Seismic for Exploration

Abstract

As commitment seismic for exploration permit WA-477P, Shell acquired a 3D broadband seismic survey utilising variable depth streamers and a multi-level airgun source. The application of this combined technology for the first time in Australian waters was intended to attenuate seismic ghosts inherent in conventional seismic surveys. The successful deployment of the method has brought new insights into the processing and interpretation of broadband seismic that raise challenges in providing the deliverables necessary for exploration turnaround cycle time. By tailoring the processing workflow, while investigating and testing new algorithms, products were available to meet exploration requirements to mature prospects for early decisions.
