The company-history website supplies a variant with a red field and white devices.
The company website dates Continental Oil & Transportation to 25 November 1875 at Ogden, Utah, and its merger with Marland Oil to 1928, creating Continental Oil at Ponca City. Lloyd’s gives differing sequences: a 1920 Marland formation followed by Continental Oil in 1929, later revised to an amalgamation of the two companies in 1875. The Conoco Inc. name was adopted in 1979. Merger with Phillips Petroleum on 30 August 2002 created ConocoPhillips.
Conoco belonged to Standard Oil Trust in 1885–1913 and to E.I. Dupont de Numours from 30 September 1981 until its independent flotation on 22 October 1998. Shipping interests included Conoco Ltd., Conoco Europe and Conoco Shipping; the latter managed Conoco’s vessels. World Wide Transport is recorded as an associate. Conch Methane Tankers was a joint venture with Shell-Royal Dutch. Early vessel names began with Conoco.
