Although South Dakota has modest production with proved oil reserves mainly located in Harding County, South Dakota also remains largely under-explored. Harding County produces the bulk of the state’s crude oil and natural gas, mostly from traditional vertical wells. Fall River County also has a history of exploration and production. Oil production in South Dakota has been fairly steady for decades.
