Following the strike at Spindletop, Cullinan partnered with Arnold Schlaet to form the Texas Fuel Company in Beaumont with funding from an investment group run by former Texas governor James S. Hogg and other investors. In 1905, as the new company rapidly expanded its operations, it moved its corporate headquarters to Houston.
