A Clearer Image
Four new large-scale MultiClient products in our northern Europe data library are built with 100% GeoStreamer data. Each GeoStreamer PURE survey is a single contiguous dataset on the same grid, fully merged and depth processed with state-of-the-art workflows, delivering subsurface images with clarity, accuracy and reliability that is only possible with true broadband acquisition.
The PGS Full Waveform Inversion (FWI) solution uses diving waves, refractions and reflections together to deliver deep velocity model updates in a stable manner without relying on very long offsets. Conventional FWI high wavenumber artifacts and cycle skipping problems are avoided by using a combination of a clever imaging condition and elegant regularization within the inversion scheme.
Wide-tow seismic acquisition is popular in the current oil and gas market as it maps areas faster, and time is money. Unfortunately, it has severe drawbacks in shallow areas. With separated wavefield imaging it is now possible to enjoy the efficiency of wide-tow in any water depth.
