Osage Nation speeds up orphan well cleanup as federal oversight recedes

The Osage Nation’s Department of Natural Resources is accelerating its pace of plugging orphaned oil and gas wells across its reservation in northeastern Oklahoma following a significant shift in federal oversight. The Nation’s DNR has plugged approximately 160 wells since the program began, with 70 to 80 completed this year alone, while inspecting thousands more across the reservation’s approximately 1,470,559 acres.

A key change occurred in March when the Bureau of Indian Affairs’ Orphan Wells Plugging Office revised its tribal grant guidelines, determining that orphan wells without responsible parties fall outside federal jurisdiction. Previously, the BIA’s Osage Agency approved every plugging permit filed by the Nation and reviewed applications for compliance with environmental and historical preservation regulations, a process that could extend 120 to 130 days. Under the new framework, the Nation can proceed with orphan well plugging with minimal BIA involvement, reducing permitting timelines to one to two weeks.

The acceleration addresses longstanding criticism of the program’s sluggish start. An Interior Department Inspector General report from February found that as of the end of 2024, the Nation had completed only 14 of 290 planned Phase 1 wells. Contributing factors included staffing shortages at the BIA’s Osage Agency, which operated under a federal hiring freeze with minimal field personnel available to verify permit applications. The Nation has since submitted 217 permits, with the agency approving 90 by late January.

While the reduced oversight streamlines operations, challenges remain. DNR personnel continue coordinating with the BIA to verify whether wells have responsible parties and confirm the status of associated leases. Many of the orphaned wells have been inactive for decades, with inaccurate historical records complicating remediation efforts. Department officials report discovering new wells regularly during fieldwork and encountering wells plugged to standards now considered inadequate, sometimes requiring extensive cleaning and cement work that can take from days to months per site.
