Updated force majeure on ANR Pipeline's reversed Southeast Mainline
Updated FM on ANR's reversed Southeast Mainline. Gulf LNG feedgas reads bullish on supply tightening; Appalachian basis reads bearish as gas strands.
An updated multi-week force majeure on ANR's reversed Southeast Mainline curtails southbound Appalachia/Midwest-to-Gulf throughput. Gulf LNG feedgas tightens as less Appalachian supply reaches the export terminals; Dom South and Midwest receipts widen as gas strands upstream.
