Conoco Inc. was an American oil company founded in 1875 as the Continental Oil and Transportation Company. Based in Ogden, Utah, the company was a coal, oil, kerosene, grease and candles distributor in the West. Marland Oil Company (founded by exploration pioneer E. W. Marland) later acquired the assets (subject to liabilities) of Continental Oil Company, for a consideration of 2,317,266 shares of stock. On June 26, 1929, Marland Oil changed its name to Continental Oil Company and moved its headquarters to Ponca City, Oklahoma. 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.
