Processing & Storage

Hess Midstream Partners has a 20 percent controlling economic interest in a large, strategically located gas plant and 100 percent ownership of a propane storage terminal.

Tioga Gas Plant

The Tioga gas plant is one of the largest natural gas processing and fractionation facilities in North Dakota. It receives natural gas produced from Hess-operated and third-party operated wells in the Bakken through its and third-party gathering systems.

The plant has the capacity to process 250,000 Mcf per day of natural gas and a planned debottlenecking project will increase that to 300,000 Mcf per day in 2019. It can fractionate 60,000 barrels and store 87,000 barrels per day of Natural Gas Liquids (NGLs) for export via two pipelines – Vantage and Alliance – and the Tioga Rail Terminal.

The plant features NGL truck loading racks with an aggregate loading capacity of 11,000 barrels per day of propane to serve the local market, and tanks to store approximately 36,000 barrels of propane, 18,000 barrels of butane and 34,000 barrels of natural gasoline.

A total of 190,000 Mcf per day can be exported to the Alliance Pipeline, the Northern Border Interstate Pipeline, the Williston Basin Interstate Pipeline and gas lift operations in McKenzie and Williams Counties.

A Compressed Natural Gas (CNG) terminal is capable of compressing approximately 2,500 Mcf per day of natural gas and loading more than 100 light-duty CNG-fueled vehicles and up to 10 CNG cylinder trailers per day for Hess’ drilling operations.

Mentor Storage Terminal

Hess Midstream Partners operates an underground propane storage cavern and a rail and truck loading and unloading facility on 40 acres in Mentor, Minnesota

Approximately 328,000 barrels of propane can be stored on site to mitigate the impact on operations from seasonal variation in demand. The terminal also has a dehydration facility, and rail and truck loading racks capable of injecting and withdrawing 6,000 barrels of propane per day. The propane is sold regionally or exported by interstate rail.
