Oneok Partners LP, Tulsa, has suspended construction on 500 MMcfd of gas processing capacity at three plants in theWilliston basin of North Dakota, Powder River basin in Wyoming, and Anadarko basin in Oklahoma. The actions are in response to lower commodity prices, especially for natural gas and NGLs, the company reported in its Feb. 24 earnings call. Terry K. Spencer, Oneok Partners president and chief executive officer, said the company will spend no more on these projects “until market conditions improve” when it will “quickly reestablish completion dates.” details on the three plants are as follows: • In mid-2014, Oneok announced plans for the 200-MMcfd Knox plant in Grady and Stephens counties, Okla. It was to spend $365-470 million by expected plant start-up in late 2016. The Knox plant was to increase Oneok’s Oklahoma gas processing capacity to 900 MMcfd. Estimated costs included $175-240 million to build the plant and $190-230 million to build related systems, including gas gathering pipelines and compression (OGJ Online, July 24, 2014).
