United Refining Company can trace its beginnings back to 1902 when nine other oil refineries operated in the Warren, Pennsylvania area. The company was organized by a small group of businessmen who wanted to provide a new source of lubricating oils. A year later, increasing business made it prudent to install stills and other equipment to process crude oil from local wells. In the years that followed, United continued to expand its refinery, transportation and marketing network to its present form. Following is a list of the most significant corporate activities from the beginning days to the present era:

  • In 1912, United participated in a pipeline project that linked Warren with the producing areas of West Virginia to assure crude supply for the refinery.
  • In 1923, United sold its interest in the West Virginia Pipeline Company and purchased two lines extending from Warren to Bradford, Pennsylvania. A purchasing office and field organization were established in Bradford and construction of gathering lines was begun.
  • In 1929, United formed the Emblem Oil Company for the retail marketing of gasoline and other petroleum products in northwestern Pennsylvania and western New York under the “Keystone” brand name.

  • In 1971, United constructed and placed into operation a 78-mile 12-inch crude oil pipeline that connected the Warren Refinery with a common carrier pipeline system at a terminal in West Seneca, New York. The Rochester, New York terminal was also acquired at this time.
