A famous fountain in the Groznyi oil field in the northern Caucasus, which began to flow in August 1895, was estimated to have thrown up during the first three days 1,200,000 poods (over 4,500,000 gallons, or about 18,500 tons) of oil a day.
The Appalachian oil field extends northward from West Virginia and Pennsylvania into Cattaraugus, Allegany and Steuben counties.
Extending from the south-west corner of the state through Greene, Washington, Allegheny, Beaver, Butler, Venango, Clarion, Forest, Elk, Warren, McKean and Tioga counties is the Pennsylvania section of the Appalachian oil-field which, with the small section in New York, furnished nearly all of the country's supply of petroleum for some years following the discovery of its value for illuminating purposes.
Lima is situated in the centre of the great north-western oil-field (Trenton limestone of the Ordovician system) of Ohio, which was first developed in 1885; the product of the Lima district was 20,575,138 barrels in 1896, 15,877,730 barrels in 1902 and 6,748,676 barrels in 1908.
Once an oil field is emptied, there is no more oil that will 'grow' there as it's the decomposing mass from the past.
