Pollution, management, and mitigation of idle and orphaned oil and gas wells in Alberta, Canada

Abstract

Alberta has extensive non-renewable energy resources which contribute to the Canadian economy. A downturn in oil and gas energy prices in 2014 contributed to increased idle and orphaned wells, posing potential environmental and human health risks, as well as an economic burden on the province of Alberta. Idle and orphaned wells contribute to local adverse environmental and human health effects from soil and groundwater contamination to greenhouse gas emissions. With increasing numbers of idle and orphaned wells, current monitoring measures, including regulation and cost to identify well leakage, are insufficient. Current policy measures to manage idle and orphaned well environmental liabilities were found to be inadequate to cover cleanup costs. With oil and gas prices showing no signs of rebound, these idle and orphaned well liabilities need to be addressed. This paper discusses potential environmental risks that idle and orphaned oil and gas wells pose, compares Alberta’s current monitoring and policy initiatives to those in other provinces as well as the USA, and recommends future management strategies to mitigate the issue.
