As we learned from our DJ midstream field trip this week, DCP’s Plant 11 (O’Connor II plant) has been running at a constrained ~100 MMcfd since its early Auguststart-up, well below total capacity of 300 MMcfd (including 100 MMcfd of bypass) as a result of continued tightness in residue gas takeaway. This constraint along with DCP/WES plant maintenance downtime is likely to result in more tempered basin-wide growth in Q3. However, FERC’s approval of TGE’s Cheyenne Connector is the last hurdle for DJ infrastructure debottlenecking, and sets the basin up for meaningful growth in 2020.” Source: Wall Street research – William Featherston, Credit Suisse, 9/20/2019 1.
