Company Profile

  • Vendor Name: Conoco
  • Headquarters: Houston, Texas
  • Year Established: 1875
  • Area Served: Worldwide


Conoco Inc. was known as the Continental Oil and Transportation Company, which founded in Utah in 1875. Marland Oil Company acquired the company and in 1929, changed the name to the Continental Oil Company. (The original Conoco logo used from 1930-1970 was actually Marland Oil Company’s logo.)

Conoco was an important supplier to the U.S. government during World War II and became a worldwide corporation after the war ended. The company became a subsidiary of DuPont in 1981. That same year, Seagram Company Ltd. tried to take over Conoco, but failed and instead became DuPont’s largest shareholder by 1995.

In 1998, Conoco and DuPont separated and Conoco went public under the name Continental Oil Company. It acquired Gulf Oil’s Canadian operations in 2002 and merged with Phillips Petroleum Company that same year to form what is now ConocoPhillips. Despite the new name, the company still offers a Conoco gas card.
