The plant is associated with Kinder Morgan's SACROC business in the Permian Basin, which produces some 50,000 barrels of oil per day via enhanced oil recovery, a technique that injects carbon dioxide underground to force more oil out. The company also sells carbon dioxide to third parties.

The company could not provide a timeline for restart plans because an investigation into the cause of the incident was still underway.
