Turn the Pipe Around - Will Crude Soon Be Flowing South on Capline?

Time and again, the repurposing of existing assets like pipelines and marine terminals to meet changing market needs has proven to be a winning approach. After all, if a lot of what you need is “already there” — as we said in today’s song title — why build something entirely new? That use-what-you’ve-got tack is a key driver behind MPLX and Crimson Midstream’s recently unveiled Swordfish Pipeline project, which by early 2020 would enable large volumes of crude oil to flow south from the St. James, LA, market hub to the Clovelly storage hub — a key crude distributor to area refineries and the jumping-off point for crude exports on fully loaded Very Large Crude Carriers (VLCCs) via the Louisiana Offshore Oil Port (LOOP). The companies also envision using other existing pipelines — including a possibly reversed Capline — as well as the soon-to-be-finished Bayou Bridge Pipeline to feed crude into Swordfish. Today, we review the MPLX/Crimson plan and assess how it might boost the export cred of LOOP, which is currently the only Gulf Coast port that can fill a 2-MMbbl VLCC to the brim without reverse lightering.

Well, it’s finally going to happen! Without major fanfare, Plains All American and Marathon Petroleum announced earlier this month that they have sanctioned the reversal of the 40-inch-diameter Capline crude oil pipeline, a move that will enable light crude to flow south on that pipe from the Memphis area to St. James, LA, starting late next year and light and heavy crude to do the same from Patoka, IL, by early 2022. Also, Plains said it has committed to expanding the existing Diamond Pipeline between Cushing, OK, and Memphis, and extending that eastbound crude pipe from Memphis to a new interconnection with Capline. Light-crude service on the expanded, extended Diamond will commence in late 2020. Today, we review the newly sanctioned projects and their significance to U.S. and Canadian producers, Louisiana refiners and Gulf Coast exporters.

Over the next few months, a variety of market players — crude oil producers, midstreamers, refiners, and exporters — will be making preparations for one of the most anticipated infrastructure additions in recent years. Actually, it’s not technically new; it’s the long-planned reversal of the 632-mile, 40-inch-diameter Capline, which for a half-century transported crude north from St. James, LA, to Patoka, IL. Line-filling will begin this fall and Capline will start flowing south from Patoka in January 2022, providing Western Canadian and other producers with new pipeline access to Gulf Coast markets. Upstream of Patoka, the impending reversal has been spurring the development of new pipeline capacity to supply the soon-to-be-southbound Capline, and in Louisiana, refiners and exporters have been making plans for the crude that will be flowing their way into St. James. Today, we discuss the broad impacts of the “new” Patoka-to-St.-James pipeline.
