The County Binders include drilling reports for section of townships in various counties. They include date, name of drilling company, location of drilling, types of layers the company drilled through, types of minerals, oil, and other materials found, depths at which materials were found, and thickness of the material found, as well as other information. The County Binders are filed in alphabetical order by the name of the county, and then by township name within each county.
