Kansas-based Tallgrass Energy has announced that both its Cheyenne Connector pipeline and Rockies Express Pipeline (REX) Cheyenne Hub Enhancement Project have now begun commercial service. Tallgrass and DCP Midstream each hold a 50% interest in the 70-mile Cheyenne Connector, which flows natural gas supplies from processing facilities in the DJ Basin in southern Weld County, Colo., to the REX Cheyenne Hub south of the Wyo., border. There, the REX Pipeline connects and intersects with numerous other pipelines—including several that Tallgrass has modified for bi-directional flow—and provides DJ gas first firm access to West, Midwest, Southeast and Gulf Coast markets. DCP is one of the largest oil and gas operators in the DJ.
