By 1929, it had become a fully integrated oil company.<ref name="company">{{cite web| url=https://www.corp-research.org/conocophillips |title=ConocoPhillips and Phillips 66: Corporate Rap Sheet |work=Corporate Research Project}}</ref> The company was a [[coal]], [[oil]], [[kerosene]], grease and [[candle]]s distributor in the West.

In 1929, Conoco merged with the [[Marland Oil Company]].<ref>{{cite web |url=https://www.okhistory.org/publications/enc/entry.php?entry=MA026 | title=Marland Oil Company |work=Oklahoma Historical Society}}</ref>

[[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.<ref>{{cite web |url=https://aoghs.org/this-week-in-petroleum-history/may-2-2/ |title=This Week in Petroleum History, April 29 – May 5 |work=American Oil & Gas Historical Society}}</ref> Conoco was based in Ponca City until 1949, when it moved to Houston, Texas.
