A PETROLIFEROUS HISTORY OF KENTUCKY AND VICINITY, PRE-DRAKE TO BIG SINKING
To put Kentucky into perspective, this history begins with Evans's 1755 map, "Middle British Colonies in America," which shows the occurrence of resources important to settlers: salt springs, coal, rapids, and gentle river courses. In pre-Drake Kentucky, wells supplied oil for lamps and medicine; cannel coal was distilled to lamp oil; gushers made worldwide news; and a geological survey took note of oil and gas springs. These events are related to others in Ohio, Ontario, Pennsylvania, and West Virginia, and provide the foundation on which the modern petroleum industry was built.
Kentucky's oil industry grew steadily from the formative pre-Drake years to the discovery of the Big Sinking Field, Lee County, the state's only giant oil field, which has produced more than 100 million barrels of oil to date. Big Sinking was discovered in 1918, but the history of petroleum in the area begins in 1852 when explorers searching for coal to fuel local iron furnaces accidentally discovered oil. The development of the Big Sinking Field provided the financial base for Kentucky's largest private energy company, Ashland Oil.
