Abstract
Summary
Many papers over the past few years have delved into the challenges, and subsequent rewards, of better determining the frequency content of our broadband seismic data. In this paper we will use a broadband dataset -acquired and processed - from the Northern Danish Central Graben to highlight a practical workflow that optimally extracts usable broadband wavelets for inversion purposes. Furthermore, low-frequency phase uncertainty was addressed during inversion testing yielding a surprisingly significant effect on the inversion result.
