Abandoned & Orphan Well Program

It is estimated that hundreds of thousands of oil and gas wells have been drilled in Pennsylvania since 1859. Although operators are responsible for plugging wells when oil and gas production is no longer economic, there remain thousands of wells in the state that have no identifiable responsible party to complete this work.

DEP's Abandoned and Orphan Well Plugging Program was established under the authority of the Oil and Gas Act to plug oil and gas wells with no responsible party. If not addressed properly, wells have the potential to cause health, safety or environmental concerns.

If you discover a well on your property, DEP is available to ensure that it has been properly identified and that any potential environmental issues are addressed. You can contact DEP by calling one of our district offices:
