SOUTHERN UTE INDIAN TRIBE: Fugitive Methane Recovery from Coal Outcrops

Oil and Gas Sector

This project is located on the Southern Ute Indian Reservation, along the steeply dipping Hogback monocline of the San Juan Basin in southwestern Colorado. The coal seams crop out along the monocline, and methane escapes to the atmosphere from this outcrop. Wells were placed in a picket line formation close to the outcrop in order to reduce the amount of methane seepage to the atmosphere. Carbon credits are generated for capturing the methane that would have otherwise escaped to the atmosphere. Koveva helped with the optimization of methane captured from these wells.
  • Optimize methane production from picket line fence methane capture wells.
  • Investigate any changes in methane (e.g. flow and compositions) that are produced from the picket fences.
  • Transfer production know-how to the Southern Ute Indian Tribe.
  • Tie the production into existing gathering lines.
