In 1900, there were 8,000 wells within 50 miles of Marietta, producing a million barrels of oil per month. The greater number of these wells were within 25 miles of the city itself. Many of Marietta's historic homes and buildings were constructed from oil profits. Fast forward to 2012 and this region of Ohio may once again see a boom in oil and gas exploration. A few years ago we began hearing about the Marcellus Shale and horizontal drilling. There has been a lot of press coverage of drilling in Pennsylvania, New York and West Virginia. Drilling is also occurring in Ohio in counties to our north.
