Richard Hammack discusses the December special section in The Leading Edge – orphaned and abandoned wells.
When we think about the environmental challenges we face, orphaned and abandoned wells might not be the first thing that comes to mind. However, as this episode reveals, the issue is far more widespread and impactful than many realize. Richard expertly navigates us through the subtle yet critical distinctions between orphaned and abandoned wells, unraveling the complexities of these seemingly dormant structures that dot landscapes worldwide.
The episode offers a fascinating exploration of innovative detection methods, from airborne magnetic sensors to the precision of drone technology, revealing how over 90% of steel-cased wells can be located. In contrast, wooden-cased and casing-removed wells present a formidable challenge.
Listeners will be taken to the historical oil fields of Pennsylvania, where wooden casings from the Civil War era elude magnetic detection, and to the vast terrains of Wyoming, where the quest to find these environmental hazards is equally urgent. The discussion also addresses the potential impact of the Infrastructure Investment and Jobs Act (U.S.) on future endeavors to address these wells.
Richard Hammack is the Research Group Leader at the U.S. Dept. of Energy-National Energy Technology Laboratory in Pittsburgh, PA, USA.
