This October 2015 issue of the RECORDER focuses on the Atlantic conjugate margins. Most of the basins of the margins of Eastern Canada are still under-explored despite ongoing production in some basins since the 1990’s. Exploration activity in Eastern Canada has recently been invigorated by Statoil and Husky’s success in the Flemish Pass Basin and by deep-water success in other Atlantic margins.
In 2014, the 4th Atlantic Conjugate Margins Conference was held in St. John’s Newfoundland. It brought industry personnel and academic researchers together to present their ideas on the stratigraphy and structural framework of the basins of the Atlantic margins†. The papers in this issue were inspired by themes and presentations at the conference. Selected papers address crustal thinning in the Orphan Basin, source rock potential of the Scotia Basins and the integration of rock physics with geopressure analysis.
The first article, “Evidence for Hyper-extended Continental Crust in the East Orphan Basin from Seismic Reflection Data and Potential Field Forward Modelling and Inversion” by Dr. J. Kim Welford of the Department of Natural Resources, Government of Newfoundland and Labrador, and Deric Cameron, James Carter and Dr. Richard Wright of Nalcor Energy Oil & Gas, provide us with new insight on the Flemish Pass/Orphan Basin where a thin crust underlies an area of Cretaceous fan deposition. The research inverted new gravity data and compares the results with modern, broadband seismic data.
The second article, “Source Rocks and Petroleum Systems of the Scotia Basins” by Ricardo L. Silva, Carlos Wong and Prof. Grant Wach of the Dalhousie University Basin and Reservoir Laboratory, presents source rock research in Eastern Canada which is the central element of any petroleum system and, most often, a key risk when exploring new frontier areas.
The third article, “Exploration in Frontier areas and Deep-Water Settings: Integration of Disciplines and Universality of Rock Properties” by Dr. Alsing Selnes of Selnes Geoscience Consulting, Dr. Alex Edwards, Dr. Sam Green of Ikon Science present some insights arising from the regional rock physics project off Newfoundland that was funded by Nalcor Energy Oil & Gas Inc. They show how universal rock physics models can be used to predict the elastic properties of both shales and sands of different ages and depths if uncertainties can be constrained and integrated into the models. These models utilize well data off Newfoundland and Labrador and compare them with data from analogues in Norway. The ultimate application of this approach is in frontier basins where well control is sparse.
Commercial discoveries such as Bay du Nord in the Flemish Pass are propelling an industry renaissance in the multi-disciplinary studies of plate tectonics, petroleum systems, and source rock mapping. Research activity is also accelerating on both sides of the Atlantic. Since 2007, the North Atlantic Petroleum Systems Assessment (NAPSA) has guided and supported researchers in Ireland and Eastern Canada to improve our knowledge of the petroleum systems of the Atlantic Margins. New data on both sides of the Atlantic have provided researchers with new insights and facilitated regional studies in plate reconstruction, source rock geochemistry, regional geopressure and rock physics trends. Results of these studies are helping industry to de-risk their exploration programmes.
New industry investment and new research studies have resulted in resurgence of exploration activity for Eastern Canada, as more and more companies are awakened to the future potential of this vast, under-explored area.

About the Author(s)
Deric Cameron began his career in gravity and magnetic acquisition in Northern Labrador with Excel Geophysical Inc., after graduating from Memorial University of Newfoundland with a BSc in Geophysics in ‘96. From there he moved into seismic data processing of foothills data with CGG and Arcis, before moving to the exploration plays in the Western Canadian Sedimentary Basin and foothills of Alberta and BC with Devon. He later began working on the deep Devonian and carbonate reefs of NEBC with Petro-Canada, during his time with Devon and Petro-Canada he pursued his MSc from the University of Calgary, graduating in 2007. After graduating, he moved onto development and exploration projects with Petro Canada based on the East Coast of Canada, and then onto his current role of east coast exploration at Nalcor Energy. Deric has over 19 years of experience with a background in gravity and magnetics, seismic processing and advanced interpretation of stratigraphic and structural plays, both on shore and off shore.
Deric is a member of the CSEG, SEG and the EAGE and is a registered Professional Geoscientist in Newfoundland and Labrador (PEGNL).
Ian Atkinson has over 30 years of experience as a petroleum geophysicist with exploration discoveries in Western Canada, Africa, and the Middle East regions.
He is Chief Geophysicist and R&D Manager with Nalcor Energy - Oil and Gas Inc. His responsibilities include:
i. technical review of prospect evaluations and basin models;
ii. assessment of new venture opportunities; and
iii. management of research and development projects.
He is a member of the SEG and the EAGE and is a registered Professional Geoscientist in Newfoundland and Labrador (PEGNL). He sits on a number of university/government petroleum R&D strategy advisory committees. In addition, he is a member of the Executive Committee of NAPSA (an international R&D association created in 2005 to study the petroleum systems of the North Atlantic basins).
His research interests include seismic data inversion, reservoir characterization, autonomous robotics and artificial intelligence.
