Summary:
The Carson, Bonnition and Salar Basins offshore Newfoundland and Labrador, Canada comprise and area of approximate 150,000 km2 situated southeast of the oil prolific Jeanne d’Arc Basin. Previous exploration rounds in the 1970s and 1980s were unsuccessful at discovering hydrocarbons in the basins; however, renewed exploration efforts are ongoing in the region with recent 3D seismic acquisition, an exploration license acquired in 2015 and a land sale scheduled for 2019. Recent 2D seismic acquisition by TGS and PGS, as well as fluid inclusion studies, updated biostratigraphic reports and multibeam and seabed coring programs have enhanced our understanding of the region. This area is a branch of the North Atlantic Mesozoic rift network which experienced two main periods of rifting – Late Triassic to Mid Jurassic and subsequent reactivation in the Late Jurassic-Early Cretaceous. The multiple rift phases and salt diapirism have led to multiple structural, stratigraphic and combination play types. The Kimmeridgian has not been encountered in this region and is an unproven source rock. Other potential source rocks include Middle Jurassic, and Cenomanian-Turonian as seen at the ODP 1276. The regional studies and recent 2D seismic data are providing positive indications of an active petroleum system in the region.
