The earliest record of a permit for an oil well in Avoyelles Parish is June 19, 1920 for the Bordelon well near Goudeau. Only four wells were permitted in Avoyelles in the 1920s, with two near Cocoville and one near Fifth Ward, In 1933 the Haas oil field was discovered south of Bunkie which set off an oil boom in this part of the parish. The Haas field still produces oil today. In the 1960s, there were several wells permitted during a second oil boom for the parish. In the 1970s, much of the parish was leased for the Tuscaloosa Trend which did not fan out. In 2009, drilling began in the deeper Austin Chalk formations, with exploration of the Tuscaloosa Shale coming soon.
