5. East Texas Oil Field: The World’s Largest (1930)
In October 1930, Columbus M. “Dad” Joiner and A.D. “Doc” Lloyd discovered the East Texas Oil Field with the Daisy Bradford No. 3 well in Rusk County. This vast reservoir spanned approximately 43 miles long and 12.5 miles wide, extending into parts of Upshur, Gregg, Rusk, Smith, and Cherokee counties. By mid-1931, daily production reached 303,750 barrels, making it the largest oil field in the world at that time. The discovery led to a significant migration of workers and investors, transforming the region’s economy and contributing to the global oil market’s volatility (tshaonline.org).
