18 Winter 2017/2018 Projected to meet market storage working inventory target of 116 MM Dth on Nov 1 Working inventory on Nov 1 estimated at 117 MM Dth Field storage has space to inject Market area maintenance projects to be complete by early Nov. No expected impact Expected changes in pipeline flows: REX receipts will increase on Gulf Coast Deliveries to LNG export facilities will continue to increase Deliveries to Mexico markets will continue Traditional supply basins: TX-OK will remain strong Midcontinent will remain at capacity 18
