From the Annals of the Wildcatters – In 1928, Carl G. (the Big Swede) Cromwell drilled the world’s deepest oil well. Cromwell was the drilling superintendent of the Texon Company. Texon was working the rapidly expanding field on University of Texas land in Reagan County. He also acquired his own leases and became known as an honest, generous, free-spirited wildcatter. In association with company engineer Clayton W. Williams, Cromwell experimented in drilling deeper than the average 3,000 feet. In 1926 Williams located a site and Cromwell’s crews began work. In late November 1928, because of mounting expenses and problems, Cromwell was directed to shut down. Instead, he disregarded orders, went into hiding, and kept drilling. On December 4, the well came in at 8,525 feet. It was the deepest oil well in the world for another three years.
