The Trenton Field located in east-central Indiana (fig. 1) was America’s first giant oil field and the focus of an oil and gas boom that started in the late nineteenth century (Rupp, 2017). Thousands of wells were drilled to fuel industries that were attracted to the region by this abundant energy resource. Unregulated drilling that wasted much of the resource led to the rapid decline in production in the Trenton Field in the early twentieth century. While significantly depleted, the field still contains active oil and gas wells. The greatest concentration of wells is centered in Wells and Grant Counties, but the field extends south into Decatur County (fig. 1) where wells are still producing small quantities of gas from the Trenton Limestone (Ordovician). Some of these wells are less than a mile from the eastern boundary of Bartholomew County.
