Capping wells, particularly non-performing or abandoned oil and gas wells, is considered a form of environmental cleanup. This process, also known as well plugging or well abandonment, involves sealing the well to prevent the release of hydrocarbons, methane, or other pollutants into the environment. Capping wells helps to:

• Prevent Groundwater Contamination: By sealing off the well, it prevents any potential contamination of groundwater from residual oil, gas, or chemicals.
• Reduce Methane Emissions: Methane, a potent greenhouse gas, can escape from abandoned wells. Capping these wells helps to reduce these emissions, contributing to climate change mitigation.
• Restore Land: The process of capping wells often includes surface restoration, which can help return the land to its natural state, making it suitable for other uses.

Thus, capping wells is a crucial environmental practice aimed at mitigating the negative impacts of inactive or abandoned wells on the environment.
