Tallgrass Energy and Silver Creek Midstream agree to expand JV

Tallgrass Energy and Silver Creek Midstream have agreed to expand their Powder River Basin (PRB) joint venture. The expanded JV, Powder River Gateway, will own the Iron Horse Pipeline, the Powder River Express Pipeline (PRE), and crude oil terminal facilities in Guernsey, Wyo. 

Both Iron Horse and PRE will transport crude oil produced in the PRB from Silver Creek’s Pronghorn Terminal to Guernsey, Wyo. where the crude oil has access to Tallgrass’ Pony Express crude pipeline system and two other existing takeaway pipelines. Tallgrass will operate the JV and own 51 percent of Powder River Gateway; Silver Creek will own 49 percent.

Iron Horse, an approximately 80-mile, 16-inch crude oil pipeline currently under construction, will have an initial capacity of approximately 100,000 bpd, is expandable up to 200,000 bpd and is expected to be in-service in the first quarter of 2019. PRE is an approximately 70-mile, 12-inch crude oil pipeline, with a current capacity of 90,000 bpd expandable up to 125,000bpd. The crude oil terminal facilities in Guernsey, Wyo. collectively own over 340 acres, include 370,000 barrels of crude storage currently in-service and, once fully constructed, will include over 1 million barrels of storage. Powder River Gateway has existing interconnections to Pony Express, two other takeaway pipeline connections, and has the ability to access any other current or future markets at Guernsey, Wyo.

When combining Silver Creek’s existing system with its recent acquisition of additional PRB crude oil assets, Silver Creek will own and operate a total of 120 miles of existing pipeline. Furthermore, Silver Creek will commence construction in the fourth quarter of 2018 to further develop the existing gathering and trunkline infrastructure by an initial 52 miles of crude pipelines and 100,000+ barrels of additional storage.

Tallgrass, which owns and operates Pony Express and is developing both the Seahorse Pipeline and Plaquemines Liquids Terminal (PLT) projects, provides extensive downstream market access for PRB producers. Powder River Gateway intends to create joint tariffs with both Pony Express and Seahorse, providing Iron Horse and PRE shippers seamless transportation from Silver Creek’s Pronghorn Terminal to Cushing, Okla., St. James, La., export markets through PLT, and more than 3 million bpd of refining demand directly connected to Pony Express or Seahorse.

Additionally, Tallgrass is pursuing multiple expansion projects on Pony Express to meet the needs of growing PRB production. These expansion projects will be staged over the next few years, with the initial pump upgrades coming online in 2018. Pony Express intends to launch an open season for additional expansion capacity out of Powder River Gateway’s Guernsey facility, in November 2018.
