The discovery of the Ekofisk field in 1969 was a turning point for Phillips Petroleum, the oil and gas industry, and the nation of Norway.
In 1969, Phillips Petroleum Co. was in the doldrums. Earnings were in a slump, management had laid off more than 1,000 employees, and dry holes were hurting the bottom line. Company geologists were excited about prospects in the North Sea, but the company and its partners had drilled a number of dry holes offshore Norway in a two-year span.
After careful consideration, Phillips and the Ekofisk licensees fulfilled their commitment and drilled the last hole. That decision culminated in the first commercial oil well in the Norwegian sector of the North Sea and the first giant oil field in Western Europe. The discovery helped shore up Phillips’ reserves and turned Norway into a wealthy oil-producing nation.
1962
Phillips Petroleum applies for exclusive rights to explore for oil and gas in the waters off Norway — the first company to approach Norwegian authorities about the possibility of finding oil and gas in Norwegian waters.
1969
First commercial discovery
On Aug. 21, the company spuds what is meant to be its last well in the Norwegian North Sea. To avoid the risk of an uncontrolled blowout, the well is plugged, and work resumes 1,000 meters away. An oil reservoir is penetrated on Oct. 25. On Dec. 23, Phillips Petroleum informs the Norwegian government that it has discovered oil. Ekofisk is a giant discovery, originally estimated to contain more than 3 billion barrels of recoverable oil.
1971
First oil is produced in June by subsea wells to the Gulftide jack-up rig, with the oil loaded into tankers.
Prime Minister Trygve Bratteli commemorates first production with a visit to Ekofisk.
Norway officially becomes an oil-producing nation. Since Ekofisk was discovered, Norwegians have pumped billions of kroner of oil and gas from the Norwegian Continental Shelf.
Safeguarding Norway’s oil wealth
The Government Pension Fund Global, now worth approximately $1 trillion, was set up in 1990 to give the government maneuvering room in fiscal policy should oil prices drop or the national economy contract. It also serves as a tool to manage the financial challenges of an aging population and an expected drop in petroleum revenue. The fund was designed to be invested for the long term, but in a way that made it possible to draw on when required. Despite its name, the fund currently has no formal pension liabilities.
1973
Ekofisk 2/4 Q comes into use as an accommodation platform. Gulftide ceases production late in the year and is removed from the field. The Ekofisk storage tank is towed to the site.
International oil crisis Members of OPEC institute a boycott in October of countries that had supported Israel in the Yom Kippur War, leading to global shortages. This boosts oil prices by 70%, followed by a further 130% jump in December. They climb from around $2.80 per barrel before the crisis to roughly $10.50 when the crisis is over in 1974.
1974
Ekofisk 2/4 A and B platforms come on stream. Ekofisk 2/4 FTP (field terminal platform) and the southern flare stack become operational.
1975
The Ekofisk 2/4 P pumping platform and the Norpipe oil pipeline to the U.K., with the 36/22 A and 36/4 A booster platforms, become operational. Offshore loading ceases.
1977
Processing facilities on the Ekofisk tank and the northern flare stack start operation. The Tor, West Ekofisk and Cod fields are tied back to the new Ekofisk 2/4 R riser platform. Gas is piped through a new Norpipe line via the B-11 and H-7 compressor platforms to Emden in Germany.
Bravo blowout In April, during overhaul of well B-14 on Ekofisk 2/4 B, well control fails due to an incorrectly installed downhole safety valve. After eight days and several attempts, the blowout is stopped, without injury to personnel or permanent damage to the environment.
1978
The Ekofisk 2/4 H hotel platform becomes operational.
1979
The Albuskjell, Edda and the Eldfisk Complex are tied back to the Ekofisk Complex.
1980
Alexander L Kielland accident On March 27, the Alexander L. Kielland accommodation rig capsizes near the Edda platform in the Greater Ekofisk Area during a storm, killing 123 people in what would be the most serious industrial accident in Norwegian history.
This incident and the Ekofisk Bravo blowout result in increased attention to health, safety and the environment. Acts and regulations are strengthened, and equipment, procedures and training are prioritized.
1982
The Amoco-operated Valhall field produces to a new riser platform, Ekofisk 2/4 G, which is linked by a bridge to the Ekofisk tank.
1983
The Ekofisk 36/22 A booster platform is shut down.
1985
The Statpipe gas pipeline is tied to the Ekofisk Complex via the 2/4 S riser platform.
1987
All steel platforms at the Ekofisk Complex are jacked up six meters to compensate for subsidence in the seabed. To increase reservoir pressure and boost production, the water injection platform Ekofisk 2/4 K is put on stream, a huge engineering accomplishment.
1989
Ekofisk 2/4 T (tank) barrier is installed.
1991
The Ekofisk 2/4 W bridge support on the southern flare stack is turned into a water injection unit.
New carbon tax The introduction of a Norwegian carbon tax prompts the oil industry to take a number of steps to reduce greenhouse gas emissions from the NCS. Norway had always imposed strict environmental regulations on petroleum production and transport. The carbon tax reinforces the attention paid by the industry to environmental practices and strengthened Norway’s position as one of the world’s cleanest petroleum producers.
1993
The Embla field starts production through a tie-in to Ekofisk via the Eldfisk Complex.
1996
The new Ekofisk 2/4 X drilling and wellhead platform comes on stream.
1998
Phase II begins at the Ekofisk Complex. The Ekofisk 2/4 J processing platform comes on stream. Ekofisk 2/4 G, 2/4 P, 2/4 R and 2/4 S, West Ekofisk 2/4 D, Cod 7/11 A, Albuskjell 1/6 A and 2/4 F, Edda 2/7 C and the process plant on the Ekofisk tank cease. The Ekofisk West, Cod, Albuskjell and Edda fields close down.
2000
Eldfisk 2/7 E water injection platform comes on stream, the beginning of water injection in the Eldfisk Complex.
2001
Conoco and Phillips Petroleum announce their merger.
2002
ConocoPhillips is established with headquarters in Houston and a European and Norwegian head office in Tananger, Norway. The first center for integrated operations — a drilling center on land — opens in Tananger.
2005
The Ekofisk 2/4 M wellhead and process platform is installed as part of the Ekofisk Area growth project.
2006
Decommissioned facilities and tank topsides are removed at Edda and Ekofisk 2/4 T (tank).
2011
Stortinget (the Norwegian parliament) approves two major new development projects, Ekofisk South and Eldfisk II.
2012
The integrated energy company splits its activity into two independent companies, the upstream ConocoPhillips and the downstream Phillips 66.
2013
The development project Ekofisk South is completed, with start-up from the Ekofisk 2/4 Z wellhead platform and the 2/4 VB seabed installation for water injection. A new field center and accommodation platform, Ekofisk 2/4 L, replaces the old Ekofisk 2/4 H.
2015
The Eldfisk II development project is completed with the opening of the integrated platform Eldfisk 2/7 S at the Eldfisk Complex. The Tor 2/4 E platform ceases production.
2018
The Ekofisk 2/4 VC subsea water injection installation is in operation.
2019
ConocoPhillips celebrates 50 years since the discovery of Ekofisk, Norway’s first oil field.
Lykkeland
The popular Norwegian television series Lykkeland (State of Happiness in English) reflects the impact Ekofisk has had on the country. Before it came into being, the producer and writer were looking for a historical event that was pivotal in creating modern Norway. They chose Ekofisk. For a younger generation of Norwegians, the series has been an eye-opener.
The eight-part drama, which won Best Screenplay at Cannes Series Festival and has been purchased by the BBC, is set in the summer of 1969 in the small Norwegian coastal town of Stavanger. International oil companies have been drilling for years, but nothing commercial has been found. Phillips Petroleum, however, is contracted to drill a final hole — and on Christmas Eve 1969 the gas flare at the oil rig Ocean Viking is lit. The Ekofisk field has been discovered, and everything is about to change.
“The story is about the oil that came to Norway,” said series writer Mette Bølstad. “In a way, it’s about the beginning of modern society.”
Communication & Government Affairs Manager Stig Kvendseth, along with other ConocoPhillips employees, consulted on the television project. “It’s a good visual picture of Norway in 1969,” Kvendseth said. “The series visualizes in a dramatic way how Stavanger changed as a result. When Americans came, they brought new traditions.”
