The Ultracube: Revitalising Vintage Surveys
Fig. 1. Location Map showing input 3D surveys.
Twenty years ago 3D seismic data was widely considered an expensive technology and was generally applied to relatively limited survey areas, most often for field appraisal and development. .. read full article
Azimuthal Anisotropy – A New Interactive Approach Leads To More Accurate Imaging
Fig. 1. Illustration showing abrupt change of average azimuth from NATS acquisition (in reality adjacent sail line spreads overlap - not shown here for aesthetic reasons).
Over the last few years, it has become common practice to account for vertical or tilted transverse anisotropy (VTI/TTI) during the migration process. This takes account of the .. read full article
