Oil exploration and production in this area was minimal until April 17, 1919, when the Bob Waggoner Well No. 1 blew in at 4,800 barrels per day. It was the first well in what became known as the Northwest Extension Oilfield, comprised of approximately 27 square miles on the former S. Burk Burnett Wild Horse Ranch. R.M. "Bob" Waggoner's well led to a boom, and the area was suddenly thick with oil derricks. The hastily organized tent cities of Thrift, Springtown, Morgan City, Waggoner City, Bridgetown and Bradley's Corner supported the industry. Today, sparsely sited pump jacks continue to draw oil, but in far smaller quantities than the early wells of Wichita County. (2006)
