The Draugen oil field lies in block 6407/9 in the Haltenbanken oil and gas province. The field is located 150 km off the coast of Norway and 200 km south of the Arctic Circle, in water depths of 240 to 280 m.
The Draugen field was discovered in 1984 by well 6407/9-1. Five additional exploration/appraisal wells and 2D seismic assisted in delineating the reservoir
The field is hosted by a low-relief north-south-trending anticline measuring some 20 by 6 km. The reservoir lies at a depth of 1600 m subsea and has an oil column of 40 m. The main reservoir is the Late Jurassic Rogn Formation sands, interpreted as a shallow marine sand bar. A separate, smaller accumulation has also been proved in Middle Jurassic Garn Formation sands in the western part of the field.
The estimated STOOIP is 180 million standard m3. Recoverable reserves are estimated at 67 million standard m3 of oil and some 3 billion standard m3 of associated gas.
The field will be developed with a concrete gravity base structure and offshore loading. The initial development plan calls for six oil producers and six subsea water injectors. The platform will be installed in the summer of 1993, with first oil shortly thereafter. The planned plateau production rate is 14,300 standard m3 of dry oil per day.

The success of Memoir 14 and the worldwide interest shown for data on giant fields prompted AAPG to schedule a symposium on giant fields at the end of each subsequent decade. The 1968-78 symposium was held in Houston, Texas, April 1-4, 1979, and the papers were published in AAPG Memoir 30, December 1980.
The Stavanger Conference "Giant Oil and Gas Fields of the Decade: 1978-1988" was held in Stavanger, Norway, September 9-12, 1990, and is a continuation of the Giants of the Decade series.
Scientific studies and projections of future world energy demand indicate that although alternative-energy fuel sources must be actively pursued and developed, there also must be adequate petroleum supplies to bridge the gap. For the international petroleum industry, the years covered by this conference, 1978-88, were complex. They were years of boom and bust. The world's energy consciousness was boosted sharply by the effects of the 1979 Iranian revolution and the resulting embargo, which sent world oil prices to record heights. Global petroleum exploration soon surged, leading to the industry's all-time drilling high in 1981. Then came the oil price collapse in 1985, and the following years were characterized by falling oil prices and drastic budget cuts for exploration and development.
Although exploration dropped sharply during the latter part of the decade, there was a steady flow of giant oil and gas field discoveries. Using the giant field designation criteria of 500 million bbl of oil recoverable for fields in Asiatic Russia, North Africa, and the Middle East,
