The US Bureau of Land Management’s Rock Springs, Wyo., field office has launched a 30-day public scoping period prior to beginning an environmental assessment of Anadarko Petroleum Corp.’s proposed expansion of Patrick Draw field.
Anadarko is considering development of up to 125 new oil, carbon dioxide, and expansion wells in the area roughly 30 miles east of Rock Springs, the BLM field office said in an Oct. 30 notice.
It said that the field is located in a checkerboard pattern of mixed ownership covering 32,781 acres of primarily federal and private land with some state acreage. Patrick Draw field includes the Monell and Arch units, which were developed in the late 1950s to early 1960s and presently support 128 producing wells.
The new proposal includes a combination of vertical and directional drilling of 105 oil wells, 18 carbon dioxide injector wells, and two water injection wells to be developed during the next 9 years, the notice said. The planned project anticipates 160 acres of maximum surface disturbance, with the life of the wells projected to be roughly 30 years, it said.
Comments will be accepted until Nov. 30, the notice indicated.
