Pony Express Pipeline (PXP)

The approximately 760-mile Pony Express (PXP) crude oil pipeline originates in Guernsey, Wyo., and runs through Colorado, Nebraska and Kansas and connects with a refinery before terminating in Cushing, Okla. - North America’s crude oil hub and a key trading and pricing point for NYMEX WTI. PXP sources oil from the Bakken, Denver Julesburg and Powder River plays, delivering three distinct common streams for our customers - Bakken Light Sweet, Mixed Sweet and Niobrara - to the Cushing oil hub for distribution to markets across the country.

Placed in service in 2014, Pony Express has a design capacity of 320,000 barrels a day, and with drag reducing agents has the capacity to transport an additional 100,000 barrels a day.

Answering producers’ call for more pipeline capacity out of the Bakken, Tallgrass built PXP and signed joint tariff agreements with two other pipelines to seamlessly deliver Bakken crude to Cushing, Okla., and points in between. To meet the transportation needs of producers in both the Bakken and Rockies regions, Tallgrass converted a 430-mile natural gas pipeline and built another 260 miles of pipeline to extend PXP through southern Kansas into Oklahoma. Before terminating in Cushing, PXP connects to the Ponca City refinery. Adding optionality for producers in the Niobrara Shale in Northeastern Colorado and Southeastern Wyoming, Tallgrass built the 70-mile Northeast Colorado Lateral (NECL), which intersects Pony Express east of Sterling, Colo.
