Extensional rise and fall of a salt diapir in the Sørvestsnaget Basin, SW Barents Sea

C Perez-Garcia, PA Safronova, J Mienert… - Marine and petroleum …, 2013 - Elsevier
Regional extension which initiates and promotes the rise of salt diapirs can also make
diapirs fall once the supply of salt from its source is restricted. New observations on the 3D …

Improved salt imaging in a basin context by high resolution potential field data: Nordkapp Basin, Barents Sea

C Stadtler, C Fichler, K Hokstad, EA Myrlund… - Geophysical …, 2014 - earthdoc.org
The seismic imaging of salt diapirs in the Nordkapp Basin gave rise to considerable
problems in defining their shape and volume. Independent information was added by …

Accurate interpretation of salt structures plays an important role in hydrocarbon exploration.
Over the years, several methods have been applied to mapping salt structures, including …

[HTML][HTML] Probabilistic approach to Gramian inversion of multiphysics data

MS Zhdanov, M Jorgensen, M Tao - Frontiers in Earth Science, 2023 - frontiersin.org
We consider a probabilistic approach to the joint inversion of multiphysics data based on
Gramian constraints. The multiphysics geophysical survey represents the most effective …
