Data collected from the Ohio Department of Natural Resources for natural gas and oil activity in Ohio has shown a virtual increase in four stages of the process, from the number of wells with permits, number of wells in the process of being drilled, number of wells with drilling completed, number of wells producing and percent of activity in the each of 21 counties in relation to the total number of well sites.

To date, 21 counties in northeastern and southeastern Ohio have been discovered by the gas and oil industry because they are setting on top of the Marcellus and/or Utica shale formations. Both are important geologic formations because they hold large reserves of natural gas. Experts say the Marcellus in Ohio covers a very thin strip along its eastern border. But, the state is positioned to cash in on the Uticas bounty of wet gas, which covers about at least half of the state. Wet gas contains the components for both natural gas and oil production.

In June of 2012, when the first GAS&OIL magazine was published, 19 counties had 237 wells (combined) in at least one stage of the process. Listed by drilling activity and the number of well sites in each county in June: Carroll, 78; Columbiana, 34; Jefferson, 25; Monroe, 21; Harrison, 12; Belmont, 10; Stark, 10; Mahoning, 9; Guernsey, 7; Noble, 7; Portage, 7; Tuscarawas, 5; Muskingum, 3; Coshocton, 2; Trumbull, 2; Knox, 2; to Geauga, Ashland, Medina and Wayne with one site for a total of 237 wells in various stages of the process.

As of Sept. 9, 2012, the number of counties increased to 21 with the addition of Holmes and Wayne counties (with no previous well sites) bringing the total number of well sites in at least one stage of activity to 375, a 58 percent increase since the magazines first issue.

Current number of wells and percent (increase or decrease) in each of the 21 counties from June 2012 to Sept. 9, 2012:

Carroll, 139 well sites, 78 percent increase

Columbiana, 51 well sites, 50 percent increase

Harrison, 33 well sites, 175 percent increase

Jefferson, 28 well sites, 12 percent increase

Guernsey, 24 well sites, 242 percent increase

Monroe, 17 well sites, 23 percent decrease

Stark, 13 well sites, 30 percent increase

Mahoning, 13 well sites, 44 percent increase

Noble, 12 well sites, 71 percent increase

Belmont, 12 well sites, no increase or decrease

Portage, 10 well sites, 42 percent increase

Tuscarawas, 7 well sites, 40 percent increase

Coshocton, 5 well sites, 150 percent increase

Muskingum, 3 well sites, no increase or decrease

Trumbull, 2 well sites, no increase or decrease

Knox, 2 well sites, no increase or decrease

Geauga, 1 well site, 100 percent increase (no previous activity)

Ashland, 1 well site, 100 percent increase (no previous activity)

Medina, 1 well site, 100 percent increase (no previous activity)

Wayne, 1 well site, 100 percent increase (no previous activity)
