Tallgrass, Bridger Launch Open Season for Bakken Crude Expansion to Seahorse Pipeline

Tallgrass and Bridger Pipeline have launched a 35-day binding open season to secure shipper commitments for expanded crude oil capacity moving from the Bakken to the Seahorse Pipeline system.

(P&GJ) — Tallgrass Seahorse Pipeline, LLC, operated by Tallgrass, and Bridger Pipeline, LLC have launched a binding joint tariff open season seeking shipper commitments for crude oil transportation capacity from the Bakken region to the Seahorse Pipeline system.

The 35-day open season, which began Feb. 24, 2026, is designed to secure commitments for expansion capacity moving from Bridger’s North Dakota origins to Seahorse’s downstream destinations. The total expansion capacity will be determined based on shipper participation during the open season.

The companies are offering incentive tariff rates tied to long-term commitments. Prospective shippers must execute a confidentiality agreement to review detailed open season materials.

The expansion would strengthen crude takeaway options from the Bakken, linking production in North Dakota to broader downstream markets served by the Seahorse system.

Bridger Pipeline operates approximately 3,700 miles of crude oil pipelines across North Dakota, South Dakota, Montana and Wyoming. Tallgrass operates more than 10,000 miles of pipeline infrastructure across 14 states.
