The nature of the Brent delta, North Sea : a core workshop

Since 1984 the Hydrocarbons· Research Group of the British Geological Survey has run a series of core workshops to illustrate the reservoir rocks of the UK North Sea. These workshops have made extensive use of the unique archive of North Sea core material stored at the BGS/D.En core store in Edinburgh. This workshop will provide the opportunity to examine the sediments of The Brent Group, the principal hydrocarbon reservoir in the northern North Sea. "Hands-on" examination of the core is encouraged, as is full discussion of the concepts and ideas presented at the workshop. The sequences illustrated all lie within the East Shetland Basin (Fig 1). To the west lies the East Shetland Plataform, where Tertiary strata rest on Devonian or older rocks, and to the east lies the NNE-SSW trending trough of the Viking Graben with its thick Hesozoic-Tertiary fill. . Both N-S and NE-SW faults cut the Jurassic in the East Shetland Basin. They are normal faults which bound a number of tilted blocks whose geometry has a crucial influence on the location of hydrocarbon traps.
