Q162013 3D GeoStreamer

Derisk future exploration and extend production of existing fields
Website Map for Survey MC3D-Q162013
Covering the Brae-Miller Province in the South Viking Graben, this survey extends westwards onto the Crawford Spur (East Shetland Platform) and eastwards into the Gudrun Sub-Basin.
The South Viking Graben was formed during the Late Jurassic rifting. The largest fields relate to the syn-rift Brae-Miller complex. Prospectivity extends on the Crawford Spur, with existing discoveries in the Triassic-Jurassic. Additionally, Paleocene potential also exists in the Gudrun Sub-Basin.
This GeoStreamer dataset is an invaluable tool to derisk future exploration, whilst providing the key dataset to extend production of existing fields. It also provides greater insight into the structural history and prospectivity of the area.
