A combination of 3D pre stack and post-stack time-migrated seismic data was used to examine salt structures, stratigraphy, and hydrocarbon potential in the BES 2, 100, 200 and BMES 1, 2, and 9 blocks of the Espirito Santo Basin, Brazil. Salt structures display a proximal to distal basinward transition from salt rollers, to vertical diapirs, to diapirs with overhangs and alloch-thonous tongues, and finally to salt canopies. The original autochthonous salt thickness increases following a similar proximal to distal basinward gradient.

Deformation, driven by a combination of gravity gliding and gravity spreading, has been a relatively continuous process in...
