Abstract

The Hibernia Formation is a stacked siliciclastic sequence of interbedded sandstone and shale up to one kilometer thick that was deposited across the Jeanne d'Arc Basin. It represents coarse-grained progradation into the Jeanne d'Arc Basin during the second half of east-west oriented extension of the North Atlantic Rifting phase. Published literature regarding deposition of the Hibernia Formation has been focused on the Hibernia oil field, located along the western basin margin, or as broad, generalized regional studies across the entire Jeanne d'Arc Basin. No publications exist regarding the depositional environment of the Hibernia Formation along the eastern basin margin in the vicinity of the Terra Nova, Hebron, and Ben Nevis oil fields. This thesis presents the available data in the region surrounding the Terra Nova oil field and aims to refine the depositional model of the Hibernia Formation. -- Three dimensional seismic data and fifty-one wells compose the raw data used in this study. Three wells have recovered core, totaling 150 meters over three zones, however these wells are all located in the northern half of the study area. Together the geophysical and geological data were combined to vertically subdivide the Hibernia Formation into ten depositional intervals that can be correlated across the study area. These depositional units record variations in rate of sedimentation and depositional direction as well as fluctuations between progradational and retrogradational trends. The Hibernia Formation is finally summarized as a series of block diagrams illustrating changes between successive units and overall evolution of the Hibernia Formation.
