ONEOK Opens New Offices In Sidney, MT -- May 22, 2017

From The Crude Life, data points (see first two comments):

• 20-acre complex; 60,000 square of finished office, shop, warehouse (average Wal-Mart, I believe is a million square feet, to help put this in perspective)
• room for growth
• chose Sidney: 
• it has roots there with its legacy facility
• near center of its operations in eastern Montana, northwest ND, and southwest ND
• original legacy facility was the Grasslands Plant, 15 miles southeast of Sidney
• Sidney is also where ONEOK's natural gas pipeline there which is the transition between natural gas and natural gas liquids; where ONEOK's Bakken natural gas liquids pipeline starts; moves south, taking liquids to southern markets
• article mentions bringing Lonesome Creek and Bear Creek on-line
• not mentioned: less traffic; probably more economical to build in Sidney, not Williston; also some tax advantages for workers living in Montana vs North Dakota
