Wells reporting Smackover Formation tops are indicated by a black point, and extend from Texas to Florida. Formation top depths measured in 6,764 wells range from 1,394 to 23,554 feet.
The Smackover Formation has been a prolific source of petroleum. The 1922 discovery of the Smackover oil field, after which the Smackover Formation is named, resulted in a sizeable oil boom in southern Arkansas.
In addition to being a petroleum reservoir, as of 2015, the brine from the Smackover Formation is the only source of commercial bromine in the United States.[3]
A 2022 report estimated that the lithium brine in the formation has "sufficient lithium to produce enough batteries for 50 million electric vehicles."[4]
