Continental Margin of Eastern Canada

Geochemistry and Exploration Significance of Crude Oils from the Eastern Canadian Shelf

GeoMark has completed an investigation of the geochemistry of oils and condensates from the eastern continental shelf of Canada. The study focuses on the Labrador Shelf (Saglek and Hopedale basins), Newfoundland Shelf/Grand Banks area (East Newfoundland and Jeanne d‘ Arc basins), and the offshore Nova Scotian Shelf (Sable and South Whale subbasins).

This study involved the analysis of 122 oils and from the eastern Canadian shelf, 41 samples from the Atlantic continental margin of Great Britain (Porcupine Basin and West of Shetlands area), and a single sample from the Baltimore Canyon (offshore New Jersey). The non-Canadian samples are added to contrast and compare the chemistry of similar age sources on opposing margins of the proto-Atlantic Ocean.

Each oil was characterized by an analytical program that included bulk compositional data, quantitative analysis of aromatic and saturate (terpanes and steranes) biomarkers, and determinations of stable isotope compositions of the saturate and aromatic hydrocarbon fractions. Rigorous comparison and classification of geochemical data were accomplished using cluster and principal component analyses.
