The discovery of Ekofisk oil field was announced in December 1969. The discovery was a turning point for oil exploration in the North Sea as it gave hope to the oil industry. Although the exploration in the North Sea was triggered by the discovery of the giant gas field, Groningen, but the effort in search for commercial oil rapidly declines after drilling over 200 exploratory well. Since then, most of the oil companies consider exploration in North Sea is infeasible or even impossible as the environmental conditions in the North Sea was harsh due to the strong gale-force wind, treacherous water depth and high tidal waves. Those who endured the misgivings of others prevailed and discovered Ekofisk oil Field.
