Produce or Plug (2000). Published in 2000, and funded by the United States Department of Energy, Produce or Plug, presented an update of its 1992 and 1996 studies of orphan and idle wells and presented policy makers with a snapshot of the state of orphan and idle wells in the nation.
One of the most important figures to come out of the study is the number of wells each state has on its waiting list to be plugged. In 1992 the states reported there were 21,155 wells to be plugged. That number had grown to 37,754 in 1996. The 2000 study showed that states are expected to plug 42,403 wells.
