Reglonal geophysical studies and mapping over the Grand Banks region of the Newfoundland offshore area have been carried out by C-NOPB for the last few years. A series of geophysical maps of regional markers has been constructed in the area between lat. 44-50 degrees N and long. 46-50 degrees W. The regional maps have been compiled from in-house C-NOPB mapping using seismic sections and the well data and maps submitted by the industry. Study and mapping covered: Carson-Bonnition, Jeanne d'Arc, Flemish Pass, and NE Newfoundland-Orphan basin. Bathymetry, time structure, isopachous, isochronous, gravity, and stratigraphic sequence maps were constructed at a scale of 1:250,000. The package of geophysical maps available from the C-NOPB office provides a framework for both regional and pros ect identification and should be useful in a wide range of studies. As a result of C-NOPB geophysical regional studies, a map showing hydrocarbon prospectivity of the Grand Banks has been constructed. This map shows where the reservoir and mature source rocks are most likely to occur along with the major plays.
