BLM Completes Plugging of Legacy Wells at Umiat
BLM Alaska completed plugging of three legacy wells and removal of wellheads from three additional legacy wells at Umiat in the National Petroleum Reserve in Alaska (NPR-A) in April 2015.
Umiat Wells 1, 3, and 11 were plugged and wellheads removed. In addition, wellheads were removed at Umiat Wells 4, 8, and 10, which had been plugged previously. All well casings were cut off below ground level and buried beneath a mound of gravel and soil. All six wells had been drilled by the U.S. Navy from the mid-1940s to the early 1950s.
