Discovery of East Frigg
East Frigg was a satellite of Frigg which lay in 110 metres of water 18 kilometres from the main field. The production licences were numbered 024 and 026 for blocks 25/1 and 25/2 respectively, awarded in the second licensing round in 1969, and 112 for block 25/2 awarded in 1985.
Neptune 7 spudded the East Frigg wildcat on 4 August 1973, and a 56-metre-thick gas-bearing layer was encountered at a depth of 1 915 metres beneath the drill floor. The bit then entered a seven-metre-thick oil zone.
The gas-oil interface lay at exactly the same depth as on Frigg. A preliminary production test yielded a flow of 638 000 scm of gas per day. Reserves in the field were put at nine billion scm.Third licensing roundYom Kippur and oil crisis
