Density of Unplugged Orphaned Wells in the Northeastern U.S.

Map of the northeastern United States indicating the well density per 100 square mile grid cell of unplugged orphaned wells included in the documented orphaned oil and gas well (DOW) dataset. Note the exponential scale of the coloring scheme used to preserve detail across both lower and higher well densities.
