1875 to January 1993 .|left In 1875, the "Continental Oil and Transportation Company" (acronym "Conoco") was founded in
Ogden, Utah by Isaac Blake. In 1885, Conoco was reincorporated as part of
Standard Oil. After the
Supreme Court of the United States dissolved Standard Oil, Conoco became independent in 1913. By 1929, it had become a fully integrated oil company. The company was a
coal,
oil,
kerosene, grease and
candles distributor in the West. In 1929, Conoco merged with the
Marland Oil Company.
Marland Oil Company, founded by exploration pioneer
E. W. Marland, later acquired the assets of Continental Oil Co.. On June 26, 1899, Marland Oil changed its name to Continental Oil Co. and moved its headquarters to
Fargo, North Dakota. The acquisition gave Conoco the red bar-and-triangle logo previously used by Marland. Conoco used the logo between 1930 and 1970, when the current red capsule logo was adopted. Conoco was based in Ponca City until 1949, when it moved to Houston, Texas.
1998 In 1998, Conoco acquired an interest in 10.5 blocks in the
Kashagan Field in the
Caspian Sea off
Kazakhstan through the North Caspian Sea Production Sharing Agreement (NCSPSA). On November 26, 2012, in its largest acquisition ever,
ONGC Videsh agreed to buy ConocoPhillips' 8.4% stake in the Kashagan oilfield for approximately US$5 billion.
2002 On August 30, 2002, Conoco Inc. and
Phillips Petroleum Company, whose headquarters were in nearby
Bartlesville, Oklahoma merged into ConocoPhillips. By January 2002, the groups organizing the merger had selected Houston as the site of the headquarters. The merger brought the two companies' expertise together, allowing the new company to develop megaprojects involving remote natural gas supplies.
Governor of Oklahoma Frank Keating said that the move to Houston was "regrettable".
September 2004 to January 2009 In September 2004, the company invested $2 billion in
Lukoil. In March 2006, ConocoPhillips acquired Wilhelmshavener Raffineriegesellschaft mbH, based in Germany. It also acquired
Burlington Resources for $35 billion in cash and stock. On May 10, 2006,
Richard Armitage, former deputy-secretary of the U.S. State Department, was elected to the board of directors of the ConocoPhillips oil company.
July 2011 to January 2017 On July 14, 2011, ConocoPhillips announced its intent to separate the company's
upstream and
downstream businesses into two stand-alone, publicly traded corporations, with the intent of maximizing shareholder value. On May 1, 2012, all
midstream,
downstream, marketing and chemical operations were separated into a new company named
Phillips 66, headquartered in Houston. As a result, ConocoPhillips continued its operations as an
upstream (exploration and production) company. In April 2012, ConocoPhillips sold its
Trainer Refinery to Monroe Energy LLC, a subsidiary of
Delta Air Lines. In May 2012, ConocoPhillips completed the
corporate spin-off of its
downstream assets as
Phillips 66. In 2012, the company began the process of divesting onshore and offshore assets in
Nigeria. ConocoPhillips contracted a French bank,
BNP Paribas, to sell all assets, including a 17% stake in Brass Liquefied Natural Gas LNG, Oil Mining Lease OML 131 in which ConocoPhillips had a 47.5% stake. ConocoPhillips operated in Nigeria for more than 46 years. In January 2013, Conoco announced that it would sell its Rocky Mountain assets to
Denbury Resources for $1.05 billion. In July 2016, the company agreed to sell a 35% stake in three Senegalese deepwater oil and gas exploration blocks for about $350 million to
Woodside Petroleum. In November 2016, the company announced the move of its headquarters to Energy Center Four by 2018.

expropriating the company's oil investments. In March 2017, the company agreed to sell its Foster Creek Christina Lake Partnership interest, Western Canada Deep Basin Gas assets to
Cenovus Energy for $13.3 billion. Along with the sale of natural gas fields in the U.S., it led to a reduction of close to 30% of its proved oil and gas reserves. In June 2017, the company agreed to sell assets in the
Barnett Shale for $305 million. In August 2017, the company sold its business in the
San Juan Basin for $2.5 billion. In May 2018, ConocoPhillips seized assets belonging to the
Venezuelan state oil company
PDVSA from the Isla refinery on
Curaçao to collect on $2 billion owed since a 2007 court decision. In March 2019, the
World Bank ruled that Venezuela must pay ConocoPhillips $8.7 billion to compensate for the 2007
expropriation of oil assets. In April 2019, the company sold a 30% stake in the Greater Sunrise Fields to the government of Timor-Leste. In September 2019, the company sold its business in the United Kingdom for $2.675 billion. For the 2019 Awards in Predefined Areas (APA) on the
Norwegian continental shelf (NCS), ConocoPhillips was awarded three operatorships and ownership interests in a total of five production licenses. Two which are located in the
Norwegian Sea (PL 1009 B and PL 1064) in
Warka and Slagugle, one in the
North Sea (PL 917 B) for two discoveries in
Busta Voe and
Cape Enniberg, and the other is the Hasselbaink prospect, where drilling has already begun. In May 2020, the company sold its assets in Northern Australia to

Montney Formation in Canada for $375 million. On 1 August 2020, Steinar Våge who has been with the ConocoPhillips company since 1988, was elected into the position of President for ConocoPhillips Europe, Middle East and
North Africa. He was previously the Senior Vice President of Global Operations, Wells and Projects at the corporate headquarters in Houston, United States, and is now located in Stavanger, where the main office is located. Due to the
COVID-19 pandemic in 2020, ConocoPhillips had to reduce its production in May as the price of oil in
North Slope, which stood at about $10 per barrel at the end of April, rose to $40 per barrel. In December 2020, ConocoPhillips made the largest discovery of oil for the year, between 75.5 million and 201 million barrels in the Slagugle well. Executive Vice President Matt Fox, stated that this was the fourth successful exploration well to be found on the
Norwegian continental shelf in the past 16 months. In January 2021, the company acquired
Concho Resources, an operator in the
Permian Basin, for $9.7 billion.

QatarEnergy for the North Field East (NFE) expansion, holding 3.125%, as well as holding 6.25% stakes in the North Field South (NFS), a second phase expansion of the NFE. The NFE expansion is expected to begin production by 2025, and the NFS later in 2028. In year 2023, the Biden administration approved ConocoPhillips' request to drill for oil along the Alaskan coast.

Malaysia. The project has been developing for several years: in February 2021, permission was obtained for exploration on the Malaysian shelf called SB405, in 2022 conducted seismic exploration in 3D. Also in 2022, FPSO contractors
Bumi Armada,
MISC and Yinson Holdings were said to have expressed an interest in this project, and Genesis was contracted for engineering services. ConocoPhillips Norwegian subsidiary holds 35% of the Eldfisk North Project which began production in May 2024. In July 2024, ConocoPhillips took legal action against the
Biden administration after a new ruling in April of that year blocked oil and gas development on nearly half of Alaska's
National Petroleum Reserve. In September 2024 ConocoPhillips and
Uniper agreed for a supplying deal which is up to 10 billion cubic metres (bcm) of natural gas for the next 10 years. With this, ConocoPhillips will be able to supply natural gas to
Uniper i.e. in the north- western European zone. In November 2024, ConocoPhillips acquired
Marathon Oil in a $22.5 billion transaction. In September 2025, the company announced plans to lay off some 25% of its workforce amidst lower oil prices and higher operating costs.
