Avo Inversion and Processing of Ultra-High Resolution Seismic for a Windfarm Application
Authors: K.H. Karkov, E. Dalgaard, A.T. Diaz, H. Duarte, H.J. Hansen, S. Hviid, N.C. Høegh van Gilse, L. Krogh, S. Kuppens, G. Salaün and F. Correia Summary The development of offshore windfarms has increased worldwide. A thorough understanding of the subsurface geotechnical conditions for foundation design and installation is still more important as turbines are […]

An ultra-high-resolution 3D marine seismic system for detailed site investigation
Authors: O. Monrigal, I. de Jong and H. Duarte ABSTRACT Currently, marine ultra-high-resolution 3D surveys tend to be characterized by signal frequency ranges of 0–600 Hz and bin sizes of the order of 3 to 6 metres. This may be acceptable in industry geohazard studies for top-hole well drilling, but it does not have sufficient […]

Advanced processing for UHR3D shallow marine seismic surveys
Authors: H. Duarte, N. Wardell and O. Monrigal ABSTRACT Traditionally, commercial ultra-high-resolution 3D multichannel seismic surveys have used sources with relatively low-frequency content (up to 600 Hz) with corresponding relatively low resolution. The new generation of multi-tip sparkers, however, utilising negative discharge technology, is able to produce repeatable high-frequency signals (above 2.5 kHz) with the […]
