ExxonMobil, Sentinel form second last-mile crude pipeline JV

ExxonMobil Pipeline Co. and Sentinel Midstream formed a second last-mile pipeline joint venture.

ExxonMobil Pipeline Co. LLC and Sentinel Midstream LLC have formed a second last-mile pipeline joint venture. Called Enercoast Midstream Louisiana LLC, the JV provides pipeline connectivity between crude oil terminals in Raceland, St. James, and Anchorage, La.

ExxonMobil contributed two crude oil pipelines into Enercoast: a 16-in. OD pipeline from St. James to Anchorage, and a second 16-in pipeline running from both Raceland and St. James with delivery at Anchorage. Via Anchorage, these pipelines provide connectivity to the 540,000-b/d ExxonMobil Baton Rouge refinery, Placid Refining Co. LLC’s 75,000-b/d refinery, and the 74,000-b/d Delek Krotz Springs refinery.

Sentinel contributed cash for a majority equity position in the JV and will be its operator. Enercoast began serving shippers as a common-carrier pipeline Dec. 1, 2023. 

ExxonMobil and Sentinel’s first JV formed 2 years ago. ExxonMobil contributed two crude pipelines to it as well: a 16-in. OD pipeline originating at its Webster Terminal with delivery points at ExxonMobil's 584,000-b/d Baytown refinery and Magellan Midstream Partners’ Seabrook export terminal and a 20-in. pipeline between Moore Road station and the Baytown plant (OGJ Online, Oct. 5, 2021).
