ODNR uses cutting-edge technology to locate abandoned mines

The Ohio Department of Natural Resources is ramping up its efforts to locate and address orphaned gas wells in Wayne County and across the state through advanced aerial magnetic surveys using drone technology. The initiative aims to improve public safety and environmental protection by identifying and plugging abandoned wells that could pose serious risks.

Orphaned gas wells are abandoned or unplugged natural gas wells that no longer have a responsible owner or operator to provide maintenance to the well.

Over time many wells drilled during earlier periods of natural gas exploration have been left behind as companies go out of business or cease operations, leaving these wells unattended. Without proper sealing and monitoring, orphaned gas wells pose environmental and safety risks.

“These abandoned wells can pose significant dangers due to their hidden or poorly marked locations,” Wayne County Administrator Patrick Herron said. “Beyond physical injury risks, abandoned wells can serve as direct pathways for surface contaminants to reach underground aquifers, jeopardizing local water supplies that could lead to health issues. Additionally, some wells may emit harmful gases or create unstable ground conditions, leading to structural damage or sinkholes.”

Aerial magnetic surveys are a method used to detect and map underground anomalies by measuring variations in the Earth’s magnetic field from the air. The technology can identify magnetic anomalies that indicate the presence of steel casings and other well components beneath the surface. This approach allows for a more efficient and comprehensive mapping of orphaned wells.

Once identified, the ODNR plugs these wells to eliminate hazards. Residents can report potential orphan wells for investigation by ODNR staff through the form on the ODNR website at www.ohiodnr.gov.
