Title: Stratigraphic Traps in Paleocene Sands in Balder Area, North Sea: ABSTRACT

Author(s): J. F. Sarg, L. J. Skjold

Article Type: Meeting abstract


End_Page 985------------------------------

The Balder oil field in blocks 25/10 and 11 in the Norwegian sector of the North Sea contains 25° API oil in a Paleocene deep-water sandstone reservoir. The sands were deposited from high concentration, high-energy turbidity currents as a complex of channelized sand lobes which formed a small fan. Depositional topography and subsequent submarine erosion created a geometric closure on the upper surface of the fan. Oil is stratigraphically trapped by this closure. Recognition and definition of this mounded surface on seismic records and the development of a sedimentary model has made it possible to drill successful appraisal wells after disappointing initial drilling results.
