Oil field workers are shown here following the discovery of the Richardson No. 1 well in the Smackover Pool in Union County on July 29, 1922. The south Arkansas oil boom began on January 10, 1921, when the Busey No. 1 well came in near El Dorado (Union County). The boom peaked in 1925 with 3,483 producing wells.
