Zydeco

The reversal of Shell’s Zydeco Pipeline (formerly Ho-Ho) in 2013 was a big deal. It enabled eastbound flows of a wide range of crude streams from the Houston area to the storage and distribution hub at St. James, LA and from there to a dozen nearby refineries. Soon, though, Zydeco (named for the region’s Creole music) was running full and shippers were competing for space, spurring midstream companies to consider further enhancements. New pipeline capacity being developed is planned to come online later this year and in 2017, but—with ever-changing market dynamics—will it all be necessary? In today’s blog, “Take the Long Way Home—Easing Crude Pipeline Constraints to St. James,” Housley Carr begins a series on new pipeline capacity to St. James, and whether it will meet (or exceed) market needs.

The St. James, LA crude trading hub provides feedstock to 2.6 MMb/d of regional refining capacity as well as refineries in the Midwest. St. James is also an important distribution hub for crude from North Dakota, South Texas, the Gulf of Mexico and onshore Louisiana as well as imports arriving at the Louisiana Offshore Oil Port (LOOP). Crude storage and midstream infrastructure at St. James has been expanding in recent years as the trading hub handles larger volumes of domestic production. Today we begin a new series looking at infrastructure and crude pricing at St. James.

The recent end to U.S. crude export prohibitions opens up a number of coastal infrastructure development opportunities. One of the best placed assets is Louisiana’s Offshore Oil Port (LOOP) – the largest U.S. waterborne crude receipt terminal. LOOP could become a Gulf Coast crude blending and trading hub if its infrastructure is upgraded to facilitate exports. Today we look at the existing LOOP operation and future opportunities for exports.

Pipelines delivering crude to Houston from the South Texas Eagle Ford are estimated to be half empty. Yet over 200Mb/d of crude is shipped from that basin to refineries in Houston and further east along the Gulf Coast by barge. One of the key reasons appears to be that local traffic congestion and a lack of adequate throughway pipeline capacity past Houston pushes barrels not needed locally onto the water to reach refineries in Louisiana. Today we explain the Houston crude traffic problem.
