Oil Capital of the World

The title of "Oil Capital of the World" is often used to refer to Tulsa, Oklahoma, or Kilgore, Texas which is also historically recognized as the "Oil Capital of the World" for its central role in the East Texas Oil Field, the largest oil field in the contiguous United States during the 1930s boom. Houston, Texas, the current center of the oil industry, more frequently uses the sobriquet “The Energy Capital of the World.”
