This report reviews and discusses potential research topics associated with the abandonment of oil and gas wells, referred to as orphan wells. Orphan wells are of interest and importance as there are hundreds of thousands of them across Canada, with the responsibility for these sites falling to each province or territory. Of particular relevance to CanmetENERGY Devon are issues surrounding the reclamation of well sites, and the contaminants that may enter the soil and ground water from the wells. This report focuses upon specific contaminants including hydrocarbons, salt, herbicides and sterilants, with a review of current research and information regarding remediation. The information in this report will be used to initiate new research proposals and activities at CanmetENERGY to better address risk assessment practices and the remediation of orphan well sites. The primary focus of the research needs identified relates to the understanding of soil and groundwater contamination and how to remediate contamination.
