FSB2012 3D GeoStreamer®

Unprecedented resolution of intra- and sub-basalt stratigraphy
Website Map for Survey MC3D-FSB2012
Acquired in two seasons, this high quality broadband dataset provides 3D coverage across this key exploration region with excellent sub- and post-basalt imaging. Good pre-stack fidelity and provides coverage over the Cambo, Tornado & Suilven discoveries.
A major Cretaceous to early Paleogene rift event was followed by extensive volcanism in the latest Paleocene. The main reservoir units are Paleocene sub- and intra-basaltic sandstones along the NE-trending Rosebank structural trend, generated by inversion tectonics in the Eocene.
The MC3D-FSB2012 GeoStreamer dataset delivers an invaluable tool for sub-basalt interpretation. Thanks to a very high signal-to-noise ratio and a broad bandwidth, unprecedented resolution of the intra- and sub-basalt sand bodies can be observed and reliable elastic attributes can be extracted.
