Value to Sponsors

  • Recalibration of the stratigraphy and evaluation of petroleum systems of the Central & North Atlantic Ocean conjugate margin.
  • Timely opportunity to leverage a carefully selected array of 35 wells: COST – Continental Offshore Stratigraphic Test plus commercial wells and DSDP-ODP-IODP sites, recommended by EGI corporate members.
  • Both in-house and affiliate scientist expertise and partnerships with 12 international institutes.
  • Unique world class capability in high resolution chronostratigraphy via composite standards calibrated to the 2012 time scale, and novel analytical techniques in petroleum geochemistry (e.g., HAWK pyrolysis).
  • ArcGIS delivery platform.
  1. Multi-disciplinary age and paleoenvironmental interpretation: Annotated graphic correlation charts for each study well.
  2. Chronostratigraphic cross-sections: illustrating regional chronostratigraphy and distribution of biofacies.
  3. Integrated sedimentology data and paleofacies maps for key time horizons relevant to major source rock intervals.
  4. Source rock characterization for richness, maturity, kerogen type, and kinetics
  5. Source (kerogen) type, depositional environment, and petroleum systems integration
  6. Anhydrous pyrolysis kinetic values for elected source intervals
  7. Progression onshore on conjugate margins in terms of uplift amount/ uplift rate and timing using apatite fission track analysis. This is key to understanding sediment pathways and provenance.

EGI in collaboration with industry sponsors and 12 identified research partners will generate new data and utilize a vast array of DSDP-ODP-IODP, COST (Continental Offshore Stratigraphic Test) and commercial well data to synthesize the stratigraphy and petroleum systems of the Central and North Atlantic Ocean. This will be done by an iterative process of revising existing age models and paleoenvironmental interpretation, followed by rigorous petroleum systems analyses and integration of new data generated by this research project. A key component of this project will be the integration of an extensive EGI database of over 10 previous studies carried out in the region and the inclusion of well data from multiple governmental bodies (e.g., United States Geological Survey) in the synthesis.

The main impact of this project lies in re-evaluating DSDP-ODP-IODP data comprising multiple vintages and inconsistent standards over the years, into an updated time scale (Geologic Time Scale 2012), combined with novel analytical techniques in petroleum geochemistry (e.g., HAWK pyrolysis instrumentation). The track record established in Region 1 (South Atlantic) will expand into Region 2 (Central and North Atlantic) with an efficient skills, workflow and dataset, that will assist sponsoring companies in multiple license round bids in the Central and North Atlantic Margin.

Significant license rounds have been announced within the forthcoming 1-6 years by various governments, who in many cases, operate a tax of royalty regime. This research project is therefore a timely opportunity to leverage critical well data and analysis in advance of evaluating new acreage in the region.

The world-class data combined with EGI’s formidable expertise in chronostratigraphy and geochemistry will enable an informed integration of the carefully selected Central and North Atlantic Ocean basins on a robustly linked ArcGIS platform.

Sector I: Central Atlantic Ocean

Delimited by the Sierra Leone Fracture Zone in the south, and the Newfoundland Azores Fracture Zone (NAFZ) in the north. Includes conjugate margins of the east coast of the USA and West Africa (Morocco to Senegal).

Sector II: North Atlantic Ocean

Delimited by the NAFZ in the south, and the Davis Strait/Greenland Iceland Faroe Rise in the north. Including key areas of offshore eastern Canada (Scotian Margin, Newfoundland & Labrador Sea) and its conjugate in the Rockall/Porcupine Trough, Iberia and Bay of Biscay, this is a subsequently rifted segmented of Jurassic age dominated by Upper Jurassic (Kimmeridgian) source rocks.
