Magellan Midstream and Navigator Energy Services Extend Open Season for Proposed Voyager Crude Oil Pipeline To August 30

Tulsa, OK and Dallas, TX– Magellan Midstream Partners, L.P. (NYSE: MMP) and Navigator Energy Services announced today an extension of the open season to solicit commitments from shippers for the proposed Voyager Pipeline to transport crude oil from Cushing, Oklahoma and Midland, Texas to Houston. Based on growing industry interest in the project, including from additional potential project sponsors, binding commitments are now due on August 30, 2019 by 12:00 p.m. Central Daylight Time.

The level of shipper support for the Midland origin addition, announced in March, combined with customer requests for additional grades of crude oil and condensate at Cushing, requires further evaluation of the scope of the Voyager project.  Current indications are driving the construction of 20-inch diameter pipelines from both Magellan’s Cushing and Midland terminals to Magellan’s terminal in Frost, Texas. From Frost, a 24-inch diameter pipeline would be constructed to Magellan’s terminal in East Houston; but may be amended based upon final commitments.

At the Cushing origin, the Voyager Pipeline would provide shippers optionality to originate deliveries from the Magellan-operated Saddlehorn Pipeline serving the Rockies and Bakken production regions, and from Navigator’s Glass Mountain Pipeline serving the Mid-Continent basin, as well as other connections within the strategic Cushing crude oil hub. Voyager is also evaluating additional storage and operational capability to move new grades of crude oil and condensate to the Gulf Coast.

The Midland origin enhances the project’s supply flexibility from the prolific Permian Basin.  As a result, Voyager is reviewing facility options consistent with shipper demand, which could include the repurposed use of existing Magellan pipeline and right-of-way, or new-build pipeline.  At the destination, Magellan’s comprehensive Houston crude oil distribution system could further deliver the multiple grades of crude oil to the Houston and Texas City refineries, or to crude oil export facilities such as the terminal owned by Seabrook Logistics, LLC, which is owned 50% by Magellan.

As proposed, the Voyager Pipeline is expected to have an initial capacity of up to 400,000 barrels per day, with the ability to expand if warranted by industry demand. Subject to receipt of sufficient customer commitments and all necessary permits and approvals, the pipeline is expected to be operational in early 2021.
