Petroleum geology of the proven hydrocarbon basins, offshore Norway
Authors A.M. Spencer, Ø. Birkeland and J.-O. KochThe Norwegian continental shelf stretches for over 3000 km from 56°N to 82°N and covers an area of more than 1.4 million km2 of which Svalbard and its shelf cover about 300000 km2 (Fig. I). To the north and west the shelf area is limited by the 1500m isobath and the water depth is generally less than 500 m. There are three main petroleum provinces: the North Sea, the Haltenbank area offshore mid Norway and the Hammerfest Basin in the southwest Barents Sea (Fig. 2). In this article we aim to give a brief overview of these areas, describing the hydrocarbon play types developed. Readers interested in further details can consult the selected references quoted in the bibliography (e.g. Glennie 1990).

Seismic reservoir monitoring over the Oseberg field
Authors S.E. Johnstad, R.C. Uden and K.N.B. DunlopThe Oseberg field is located in the Norwegian North Sea in blocks 30/6 and 30/9, approximately 140 km northwest of Bergen (Fig. 1). The field was discovered in 1979, and came onstream in December 1988. The Oseberg field comprises three major eastward tilted fault blocks called Alpha, Gamma and Alpha North (Fig. 2). The reservoir rocks are found within the Brent group, where the Oseberg formation is the main reservoir (Fig. 3). The total Brent group thickness is 40-200 m. Seal is provided by the Heather formation and the Cretaceous limestones and shales.
