July 2014: North Atlantic

The PlateDEF study for the North Atlantic covers the conjugate margins of West Greenland and Europe. Phase I of the study was completed in 2012 and covered the Northeast Greenland and Norwegian margins. Phase II extends the area south and is important for anyone interested in the western offshore UK, including the hyperextended basins of the West of Shetlands and the Rockall Trough. The study also includes the Jan Mayen microcontinent, Norwegian shelf, and East Greenland.

PlateDEF Multi-Client Studies

Pre-commitments now available for Q4 2016:
Nova Scotia-Morocco/Newfoundland-Iberia

GeoArctic has significant experience in the development of deformable plate models in this region. As early as 2003 GeoArctic produced a proprietary deformable plate model for a consortium of oil companies exploring the Orphan Basin, offshore Newfoundland. In 2012 GeoArctic produced a deformable plate model for the Irish and Newfoundland Governments. This helped to contribute to the success of the 2015 license round, which poduced record interest in the deep water areas of the Porcupine and Rockall basins. The new PlateDEF study will cover the Nova Scotia-Morocco and Newfoundland-Iberia conjugate margins. Armed with new data and our advanced modelling techniques we are now taking another look at the region. The new study will be fully integated with all other regional PlateDEF studies. Preliminary results will be available in the summer of 2016 and will be important for anyone evaluating the upcoming offshore Newfoundland license round in 2016.

Jan 2016: Circum-Arctic and Barents Sea

The PlateDEF plate model for the Circum-Arctic is based on years of work in the area, reinterpretation of all relevant public domain data, new gravity and structural modeling and, with permission, new interpretions of high quality seismic data from ION-GX Technology. Among other things, the model sheds light on the timing and diection of opening of the Arctic basins, the nature of the Alpha-Mendeleev ridge and the role of transform zones in the transfer of extension. It also highlights the influence of distant Arctic tectonics on the Barents Sea. The model will be invaluable for anyone with licenses awarded in the Norwegian 23rd round and for the evaluation of future license rounds in the area.

Feb 2014: Baffin-Labrador-West Greenland

The PlateDEF model provides new insights into the complex interaction between rifting, strike-slip fault zones, and Cenozoic compression. The timing of breakup, and the extent of hyper-extended crust and mantle exhumation in the ocean basins, have been re-defined as a result of the study. Modelling the northward propagation of the rift system shows a progressive development of structures which influence deposition and potential trap integrity. Mapping the geometry and connectivity of the rift basins helps to assess the critical marine connections to the Arctic and Atlantic oceans.
