Pending board approval, we expect to announce additional Williston Basin natural gas processing capacity by the end of this year.”





In addition, the Garden Creek III natural gas processing plant, originally scheduled for completion in the first quarter 2015, is now ahead of schedule and slated for completion in the fourth quarter 2014.





“The completion of this plant, now a 120-MMcf/d natural gas processing facility with the additional capital investment in compression, combined with other ongoing investments in the Williston Basin, will provide the partnership with additional natural gas and NGL volumes while also creating long-term value for our unitholders,” said Spencer.





Since 2010, ONEOK Partners has constructed or is constructing seven new natural gas processing plants and related natural gas gathering infrastructure in the Williston Basin, which will increase the partnership’s natural gas processing capacity in the region by more than 10 times by the end of 2016, compared with 2010.





Construct Demicks Lake natural gas processing facility and related infrastructure:





The Demicks Lake natural gas processing plant and related infrastructure are expected to cost approximately $515 million to $670 million and be completed during the third quarter 2016, and include:





|  |                                                                                                        
|- | -------------------------------------------------------------------------------------------------------
|• | $330 million to $430 million for the construction of the Demicks Lake natural gas processing plant; and

|  |                                                                                                                                                                
|- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------
|• | $185 million to $240 million for the construction of related natural gas infrastructure, including natural gas gathering pipelines and natural gas compression.




“Crude-oil and natural gas production in the Williston Basin continues to increase, and we remain committed to building essential natural gas gathering and processing infrastructure that will enable producers to capture and process these growing volumes and reduce natural gas flaring in North Dakota,” said Spencer. “With an industry goal to reduce natural gas flaring to 5 to 10 percent of total production in 2020 in North Dakota, we will continue to commit resources to building critical infrastructure to meet this goal. The completion of the Demicks Lake natural gas processing plant, combined with our Garden Creek II and III and Lonesome Creek natural gas processing plants currently in various stages of construction, further demonstrate our commitment to this cause.”





The Demicks Lake natural gas processing plant will be built in McKenzie County, North Dakota, the same county as the partnership’s existing Garden Creek natural gas processing plant. The Garden Creek II and III natural gas processing plants currently are under

construction and expected to be completed in the third quarter 2014 and fourth quarter 2014, respectively.





When completed, the Demicks Lake natural gas processing plant will be ONEOK Partners’ second 200-MMcf/d plant in the region. In November 2013, the partnership announced plans to construct the Lonesome Creek plant, a 200-MMcf/d natural gas processing facility, expected to be completed in the fourth quarter 2015.





Construct new natural gas compression to utilize additional Williston Basin natural gas processing capacity:





T he partnership also will invest approximately $80 million to $100 million to construct additional natural gas compression to take advantage of additional natural gas processing capacity at its Garden Creek, Garden Creek II and III and Stateline I and II natural gas processing facilities by a combined 100 MMcf/d. This is scheduled for completion during fourth quarter 2015.





“Constructing additional natural gas compressor stations across our Williston Basin system will enable us to utilize increased processing capacities at our existing Garden Creek and Stateline I and II natural gas processing plants, as well as our Garden Creek II and III natural gas processing plants that are under construction,” Spencer said.





Construct a new NGL gathering pipeline connecting to the Bakken NGL Pipeline:





In addition, the natural gas liquids segment will invest approximately $10 million to $15 million to construct approximately 12 miles of NGL gathering pipeline connecting the Demicks Lake natural gas processing plant to the partnership’s Bakken NGL Pipeline scheduled for completion during the third quarter 2016.





Capital Projects:





The partnership has announced total investments exceeding $7.0 billion through 2016 for acquisitions and infrastructure growth projects related to natural gas gathering and processing and natural gas liquids, which includes the projects described above.





These investments consist of more than $4.0 billion for natural gas gathering and processing projects, and approximately $3.0 billion for natural gas liquids projects.  Nearly $4.0 billion is for growth projects related to resource development in the Williston Basin, North Dakota.

In the aggregate, these projects are expected to generate adjusted EBITDA multiples of five to seven times.  The incremental earnings from these projects are expected to increase distributable cash flow and value to unitholders in the form of higher distributions.





After this announcement and the recent announcement of the Knox natural gas processing plant and related infrastructure in Oklahoma, the partnership continues to have a $3 billion to $4 billion backlog of unannounced growth projects.  Additional projects included in this backlog will be announced when sufficient supply commitments are obtained.





ONEOK Partners is the largest independent operator of natural gas gathering and processing facilities in the Williston Basin, with a natural gas gathering system of more than 6,500 miles and approximately 3 million acres where production is dedicated to its systems.

NON-GAAP (GENERALLY ACCEPTED ACCOUNTING PRINCIPLES) FINANCIAL MEASURES:





ONEOK Partners has disclosed in this news release anticipated adjusted EBITDA and distributable cash flow (DCF) levels that are non-GAAP financial measures.  Adjusted EBITDA and DCF are used as a measure of the partnership’s financial performance.  Adjusted EBITDA is defined as net income adjusted for interest expense, depreciation and amortization, income taxes and allowance equity funds used during construction.  DCF is defined as adjusted EBITDA, computed as described above, less interest expense, maintenance capital expenditures and equity earnings from investments, adjusted for cash distributions received and certain other items.





The partnership believes the non-GAAP financial measures described above are useful to investors because these measurements are used by many companies in its industry as a measurement of financial performance and are commonly employed by financial analysts and others to evaluate the financial performance of the partnership and to compare the financial performance of the partnership with the performance of other publicly traded partnerships within its industry.





Adjusted EBITDA and DCF should not be considered an alternative to net income, earnings per unit or any other measure of financial performance presented in accordance with GAAP.





These non-GAAP financial measures exclude some, but not all, items that affect net income. Additionally, these calculations may not be comparable with similarly titled measures of other companies.  Furthermore, these non-GAAP measures should not be viewed as
