. The field was discovered in 1876, but the size and magnitude of the field was not known until the 1880s. The field was the largest natural gas discovery up to that time, containing over 1 cubic foot (2.8316847E-10 km³) of natural gas. The field also contained the first giant oil reserve discovered in the United States with an estimated 1 Goilbbl of oil. The discovery began the Indiana Gas Boom

.

Almost all of the natural gas was removed from the field by 1910, but only about 10% of the oil was removed at that point. The lack of pressure caused by the removal of the gas led to complete stop of oil production, even though an estimated 900 Moilbbl of oil remained in the field. Beginning in the late 20th century, oil production resumed at a slow pace after advances in artificial lift

Artificial lift

Artificial lift refers to the use of artificial means to increase the flow of liquids, such as crude oil or water, from a production well. Generally this is achieved by the use of a mechanical device inside the well or by decreasing the weight of the hydrostatic column by injecting gas into the...
