Ezell Oil Field and the East El Dorado Oil Field define the industrial character of this Union County landscape, where energy extraction meets a dense network of rural settlements. Small communities like Smithville, Perdue City, and Old Union are scattered among the timber and creeks, connected by roads such as Champagnolle Rd and Industrial Rd. The terrain is deeply marked by local history, evidenced by numerous burial sites including Zion Watch Cemetery, Beulah Springs Cemetery, and the Free Union Cemetery. Waterways like Bogay Creek and Cany Creek thread through the production zones, while the Nick Springs Lookout Tower stands as a prominent landmark near the Nick Springs Oil Field. This survey captures the complex intersection of Arkansas petroleum history and established family lands just east of the regional hub.
