The BLM's onshore oil and gas program manages oil and natural gas extraction nationwide, bringing in billions of dollars to the U.S. Treasury from productive wells. But what happens if the wells we manage are no longer productive or maintained? This is the question that the Federal Orphaned Well Program is designed to answer. The program seeks to remediate orphaned wells on Federal Lands, as well as support efforts to do so from State and Tribal entities’ plugging programs.
Orphaned wells are oil and gas wells that no longer have a responsible operator to plug and reclaim the surrounding land. When no responsible party exists, the BLM steps in to secure funding and resources to plug the wells, using funds from operators' bonds and legislative programs to contract and clean up abandoned project sites. In these cases, the BLM works with operators to ensure idle wells are either brought back into production or plugged before they become orphaned.
Left unattended and unplugged, inactive oil and gas wells are environmental hazards that jeopardize public health and safety, as well as pose risks to wildlife. Emissions of noxious gases such as methane threaten to contaminate groundwater; unattended drill sites can lead to flooding and sinkholes. To prevent these dangers, the BLM works with contractors to identify, prioritize and plug orphaned wells.
According to the U.S. Environmental Protection Agency, oil and gas well plugging is a multi-step process. Before the actual plugging can begin, specialists must inspect and prepare the site, removing any existing infrastructure and production tubing. Teams then pump strong plugging materials with low permeability, such as cement, deep into the inactive wells. The placement of underground plugs at the oil and gas production zones and water aquifers seals off emissions and prevents contamination. Assuming the plug passes necessary pressure tests, and no adjustments are needed, the well is then capped, and activities begin.
