In efforts to further improve final migrated images we have developed a new methodology for post-migration multiple removal in the migration depth domain. The typical input for the prediction phase...

We present a case study of enhanced imaging of wideazimuth data from the Gulf of Mexico utilizing recent technologies; and we discuss the resulting improvements in image quality, especially in...

A data driven 3D true azimuth surface related multiple elimination (SRME) technique can be quite effective in removing surface related multiples for both narrow azimuth (NAZ) surveys as well as wide...

The Benin Ultradeep seismic survey was acquired by TGS in 2009. 2D migrated seismic data shows the boundary between oceanic and stretched continental crust occurs at a transform fault zone. Up to 4...

Chukchi and East Siberian Seas region represents one of the most remote and poorly studied areas of East Arctic. Wrangel Island is located between East Siberian and Chukchi Seas and composed of...

Wrangel Arch represents the extensive (more, than 500 km) ~ E-W trending oshore basement high, separating the well-known shelf depressions: North and South Chukchi (Hope) sedimentary basins, lled...

A new salt velocity model building methodology is proposed which allows effective testing of different salt interpretation scenarios. In this methodology, we combine the strength of efficiency from...

We present a case study of an anisotropic prestack depth migration (APSDM) project which used high-resolution, shallow tomography and anisotropic model building for a large depth migration project in...

This study is based on the series of field works on Bel kov Island (Eastern Laptev Sea region) and Khatanga Bay area (Western Laptev Sea region). It is widely known, that the Laptev Sea region is one...

It is widely accepted that the key to successful sub-basalt imaging in the Atlantic Margin region is to generate as much low frequency energy as possible. Whilst recent acquisition in the...
