Large areas of the south western Barents Sea remain unexplored. An integrated approach to the understanding of the south western Barents Sea is presented in order to determine prospectivity and risk...

To identify and define a complex salt body with rugose top and base is essential in building an accurate velocity model for premium quality depth imaging. We present a few real data examples from...

Russian Eastern Arctic shelf, including Laptev Sea, represents one of the most promising offshore areas for hydrocarbon discoveries. Nevertheless, due to the absence of offshore wells, sparse grid of...

We have developed a new methodology for predicting and removing multiples in the migration depth domain based on wavefield extrapolation and attribute based subtraction. The input for the prediction...

The sedimentary basin development of the Barents Sea has been influenced by the formation of three Large Igneous Provinces (LIPS): The end-Permian (ca. 250 Ma) Siberian Traps, the Early Cretaceous...

To attain the benefits of simultaneous shooting in marine data acquisition, either the simultaneous sources have to be placed far apart to minimize the interferences from one another or sufficient...

The continental margins off mid-Norway and NE Greenland share a common geological history leading up to breakup in earliest Eocene. The geology offshore NE Greenland is poorly understood due to a...

A constrained propeller ship noise removal technique for OBC data has been developed. The constraints include the ship lane information, global linear fitting to determine the ship movement, and the...

The conventional zero-lag crosscorrealtion imaging condition of reverse-time migration is subject to strong migration artifacts. This paper studies wavefield decomposition method under relatively...

Wrangel Island is located between East Siberian and Chukchi Seas and composed of metamorphic Wrangelian Complex and overlying Silurian, Devonian, Carboniferous, Permian and Triassic sedimentary...
