In a project with implications for moving Rockies and Bakken Shale crude supplies to the Texas coast, Magellan Midstream Partners LP and Navigator Energy Services have extended a joint binding open season to test support for Voyager, a 300,000 b/d pipeline that would run from the Cushing hub in Oklahoma to Houston.

The original open season, set to end last month, has been extended to March 29. Pending a successful open season and regulatory approvals, Voyager could be in service by late next year. The current design is a 500-mile pipeline with 20-inch and 24-inch diameter pipeline, stretching from Magellan’s Cushing terminal to its Houston area facilities.

The Magellan-operated Saddlehorn pipeline, which reaches both the Rockies and Bakken, would be connected to Voyager.

Once the northern supplies reach the Gulf Coast, Magellan said its infrastructure in Texas would allow refining or terminaling for export. When the open season was launched late last year, Magellan indicated it was evaluating a potential crude pipeline from Houston to South Texas, as well as an export terminal for very large crude carriers on Harbor Island in Corpus Christi.
