Avoiding Environmental Remediation Through “Temporary” Closure

This study examines the environmental impacts of temporary closure of inactive oil and gas wells and explores the real options available to operators, such as reactivation or abandonment. It assesses the risks of gas migration and drinking water contamination, as well as the management of Naturally Occurring Radioactive Material (NORM). The research draws on the works of Brennan and Schwartz (1985), Paddock Siegel and Smith (1988), Dixit and Pindyck (1994), Slade (2001), Mason (2001), Moll (2001), Moel and Tufano (2002) to evaluate the economic costs and benefits associated with each option.
