Frogtech Geoscience Releases New North Atlantic and North Sea SEEBASE®, Providing New Perspective for Underexplored Paleozoic Reservoirs
CANBERRA, Australia, May 28, 2017 /PRNewswire/ -- Today, Australian geoscience company Frogtech Geoscience released the North Atlantic Regional SEEBASE® Study and GIS, a new comprehensive regional study of basement architecture in the North Sea and the North Atlantic conjugate margins of Norway, Greenland, UK and Ireland.
The unique SEEBASE model visualises basement topography at the geologically complex Baltica-Avalonia-Laurentia collisional triple junction. The basement focused analysis overcomes the challenge of interpreting basement beneath basalt and/or salt on seismic data, showing that the deepest North Atlantic depocentres are floored by shallow mantle below hyperextended crust.

Basin trends in the prospective North Atlantic and North Sea were directly controlled by pre-existing Caledonian structures and reinforced during the Variscan Orogeny. Paleogeography in reconstructed space shows North Sea basement platforms as barriers between contrasting marine and non-marine clastic depositional environments in the Early to Mid-Paleozoic. Reef complexes developed above these Caledonian-cored platforms, forming important yet underexplored Paleozoic reservoirs.
The study leverages Frogtech Geoscience's proprietary potential field geophysics interpretation process that includes detailed integrations of gravity and magnetic data, basement terranes and composition, and iterative tectonic and reconstructed paleogeographic analysis, to produce the SEEBASE depth-to-basement and present-day basement heat flow model.
