Submarine fan and deltaic depositional systems of Late Paleocene and Early Eocene age contain important hydrocarbon reservoirs in the Bruce-Beryl Embayment. Early Eocene submarine fans form the main hydrocarbon reservoirs in the Forth/ Gryphon Oilfields and Frigg Gasfield and other significant oil discoveries have been made in these and in Late Paleocene fans. Large volumes of heavy oil are also reservoired in the Late Paleocene and Eocene deltas. This case study documents the sequence-stratigraphic evolution of the submarine fans and their coeval deltaic systems, places them in their subregional context and briefly reviews the main Tertiary play types. The interpretations presented here are based on a large well (170 wells), core (3 km+) and seismic database (including 3D surveys). The integration and biostratigraphic calibration of this data have led to the development of a robust sequence-stratigraphic scheme which, tied to seismic data, has allowed the more precise definition of play fairways and provided a consistent and well constrained framework within which a large number of Tertiary prospects have been evaluated.
