Sun Oil Company’s well, No. 1 Allen Jameson, was staked in September 1946 and struck oil on November 17. Intermittent drilling had gone on in Coke County for 30 years, but this discovery began a county-wide oil boom. Drilled by the Dallas firm of Roberts & Hawkins, the well hit pay dirt at 6,230 feet in fossil-bearing limestone 280 million years old. In a 24-hour test it flowed 168 barrels. Coke County recently ranked among the top quarter of oil-producing counties in Texas, with its 18 fields exceeding 6.4 million barrels annually.
