Trenton Limestone Of Northwest Ohio

NATURAL GAS was secured in the Trenton limestone near Findlay, Hancock County, in 1884, and oil in the following year. Drilling was rapid so that the production increased by leaps and bounds; in 1896, it exceeded 25,250,000 bbl., the maximum for the field. Since that time, the yield has decreased steadily and in 1921 was only 1,447,243 bbl. The territory extends as an arc of a circle from near the western end of Lake Erie southwest into Indiana, which it enters in Adams and Jay Counties. Sixteen counties are listed in Ohio but five of them combined had a new production of only 264 bbl. and they might well be omitted. Progress in the Trenton limestone field of northwest Ohio in 1923 is shown in Table 1.
