Mitigating Impact of Wave-Height on Ultra-High Resolution Seismic Data Processing

What is it about?

We present a case-study from the North Sea, where we address the challenges of ultra-high-frequency seismic data and show that carefully parameterized workflows can deliver high-resolution near-surface images crucial to de-risking the placement of infrastructure such as wind farms.

Why is it important?

Ultra-high frequency marine datasets are acquired to enable sub-metre resolution of seismic imaging for placement of infrastructure such as wind farms. These seismic datasets can be processed using modified versions of conventional towed-streamer signal-processing and imaging workflows, with attention to challenges that are unique to such acquisition settings. Such challenges include the impact of wave height on ghost reflections and uncertainty in source and streamer depths, which adversely affect image resolution.
