Modern broadband seismic data provides new insight into the Eocene-Miocene syn- to early post-rift sections of the East Java Sea (North Madura) and South Makassar Basin. Previous subsurface imaging...

A recent industry workshop in Oslo addressed the burning issues in marine seismic acquisition, including the benefits and challenges of ocean bottom seismic (OBS) methods; source solutions to emit...

The authors explain the key steps and technologies in the successful reprocessing of a legacy-sparse 3D OBC survey over the Kashagan oil field and demonstrate how it dramatically improved the quality...

The accuracy of velocity model and the amplitude reliability of an image are extremely important for a successful exploration project. By using a simultaneous inversion workflow based on a vector...

New and innovative survey design solutions for marine towed streamer acquisition were recently introduced by Widmaier et al. (2019). One of the key technical elements was the concept of wide-tow...

This paper will focus on a data driven approach for reservoir properties estimation of a recently acquired and processed multi-azimuth multisensor survey in the prolific South Viking Graben, Norway.

Offshore Newfoundland has promising hydrocarbon potential along the shelf and slope areas as proven by PGS Ultima.

The continuous wavefields method allows the simultaneous operation of multiple sources in a seismic experiment and efficient separation of the wavefields emitted by different sources. This method...

Overcoming cycle-skipping in Full-Waveform Inversion (FWI) is important for the automation of this technology and key for its success to build high-resolution velocity models.

Least-squares migration (LSM) images the subsurface through an inversion process and seeks the reflectivity model that best explains the measured data.
