"Earnings growth continued in the third quarter as natural gas liquids (NGL) and natural gas volumes increased in our highest-margin areas, despite unplanned operational outages in the Williston Basin and minor timing delays in well completions in the Mid-Continent," said Terry K. Spencer, president and chief executive officer of ONEOK Partners.

"We expect NGL volumes to continue to increase as a result of seven third-party natural gas processing plant connections made to our system this year. New connections in the Rocky Mountain region have contributed to the Bakken NGL Pipeline reaching 111,000 barrels per day in September," said Spencer. "We also expect natural gas volumes to continue to increase significantly as our Williston Basin natural gas processing plants reached full capacity and our natural gas gathered volumes reached 685 million cubic feet per day (MMcf/d) in September. Our new 200 MMcf/d Lonesome Creek natural gas processing plant, expected to be completed by the end of November, and three additional compressor stations that are expected to be completed in the fourth quarter, will provide incremental capacity to support the volume growth in the basin. Additionally, we've connected more than 720 new wells through the third quarter, and we expect to connect approximately 825 wells by the end of 2015.

"The unplanned operational outages in the Williston Basin, which have been resolved, impacted the partnership's third quarter results by approximately $16 million in the natural gas gathering and processing and natural gas liquids segments combined," said Spencer.

"We continue to take important steps to increase fee-based earnings in all three of our business segments," added Spencer. "Within the last year, we've announced new, largely fee-based investments in our natural gas liquids and natural gas pipelines segments, including the acquisition of the West Texas LPG pipeline system, the construction of the Roadrunner Gas Transmission pipeline and the expansion of the WesTex Transmission Pipeline system.

"In the natural gas gathering and processing segment, we have successfully converted a portion of our percent-of-proceeds contracts to largely fee-based contracts, resulting in a nearly 20 percent increase in the average fee collected in the third quarter compared with a year ago. We expect this rate to increase significantly into 2016, and we expect to greatly reduce our commodity exposure and increase margins," continued Spencer. "We also expect our percentage of fee-based margin in the natural gas gathering and processing segment to increase to more than 70 percent in 2016 from approximately 50 percent currently. We will continue to actively pursue opportunities to work with producer customers to increase the fee component in our agreements and expect to be substantially complete with these efforts in the Williston Basin by the end of the year."

THIRD-QUARTER AND YEAR-TO-DATE 2015 FINANCIAL PERFORMANCE

Third-quarter 2015 results were impacted positively by higher NGL volumes and natural gas gathered volumes, compared with the third quarter 2014, but were impacted negatively by low commodity prices and unplanned operational outages in the natural gas gathering and processing segment.

Third-quarter 2015 operating income reflects:


    --  Lower net realized NGL, natural gas and condensate prices; offset
        partially by
    --  Higher NGL exchange-services volumes from recently connected natural gas
        processing plants in the Williston Basin, Powder River Basin and
        Mid-Continent region;
    --  Higher margins due to changes in contract mix resulting from higher fees
        in the natural gas gathering and processing segment; and
    --  Higher NGL transportation margins, primarily from Permian Basin NGL
        volumes from the acquired West Texas LPG pipeline system.

Operating costs decreased in the third quarter 2015, compared with the same period last year, due primarily to higher scheduled maintenance and chemicals costs in the prior year, offset partially by increased employee costs from the growth of operations related to completed capital projects and acquisitions. Operating costs increased for the nine-month 2015 period, compared with the same period in 2014, due primarily to the growth of operations related to completed capital-growth projects and acquisitions.

Depreciation and amortization increased for the three- and nine-month 2015 periods, compared with the same periods in 2014, due primarily to the growth of operations related to completed capital-growth projects and acquisitions.

Equity in net earnings from investments in the three- and nine-month 2015 periods increased, compared with the same periods in 2014, due primarily to a $76.4 million noncash impairment charge in the third quarter 2014, related to an equity investment in Bighorn Gas Gathering, and higher volumes delivered to the Overland Pass Pipeline from the Bakken NGL Pipeline.

BUSINESS-SEGMENT RESULTS:

Key financial and operating statistics are listed in the tables.

Natural Gas Liquids Segment

The natural gas liquids segment benefited from volume growth of NGLs gathered and fractionated during the third quarter 2015 and through the first nine months of the year. NGLs transported on gathering lines increased approximately 49 percent for each period compared with 2014, primarily due to Permian Basin volumes transported on the acquired West Texas LPG pipeline system. Recently connected natural gas processing plants across ONEOK Partners' system, including one new third-party plant connected in the third quarter, and decreased ethane rejection in the Rocky Mountain region also contributed to volume growth. NGLs fractionated increased 7 and 5 percent in the three- and nine-month periods in 2015, respectively, compared with the same periods in 2014.

The increase in third-quarter 2015 operating income, compared with the third quarter 2014, primarily reflects:


    --  A $27.5 million increase in exchange-services margins, resulting
        primarily from increased volumes from recently connected natural gas
        processing plants in the Williston Basin, Powder River Basin and
        Mid-Continent region, offset partially by unplanned operational outages
        at the partnership's natural gas processing plants in the Williston
        Basin;
    --  A $26.1 million increase in transportation margins, primarily from
        Permian Basin NGL volumes from the acquired West Texas LPG pipeline
        system; and
    --  A $12.5 million increase related to decreased ethane rejection in the
        Williston Basin, offset partially by higher ethane rejection in the
        Mid-Continent region; offset partially by
    --  A $17.2 million decrease in optimization and marketing margins; and
    --  A $6.2 million decrease related to lower isomerization volumes,
        resulting from the narrower NGL product price differentials between
        normal butane and iso-butane.

The increase in operating income for the nine-month 2015 period, compared with the same period last year, primarily reflects:


    --  A $149.7 million increase in exchange-services margins, resulting
        primarily from increased volumes from recently connected natural gas
        processing plants, higher fees for exchange-services activities
        resulting from contract renegotiations, and higher revenues from minimum
        volume obligations, offset partially by unplanned operational outages at
        the partnership's natural gas processing plants in the Williston Basin
        during the third quarter 2015; and
    --  A $67.1 million increase in transportation margins, primarily from
        higher volumes on the acquired West Texas LPG pipeline system; offset
        partially by
    --  A $100.2 million decrease in optimization and marketing margins related
        primarily to the increased demand for propane experienced during the
        first quarter 2014; and
    --  A $26.6 million decrease related to lower isomerization volumes.

Operating costs decreased for the third quarter 2015, compared with the same period in 2014, due primarily to decreased outside services expense and miscellaneous supplies and expenses due primarily to scheduled maintenance in the prior year.

Operating costs increased in the nine-month 2015 period, compared with the same period in 2014, due primarily to the completion of capital-growth projects and acquisitions.

Depreciation and amortization expense increased for the three- and nine-month periods, compared with the same periods in 2014, due to depreciation associated with completed capital-growth projects, including acquisitions.

Equity in net earnings from investments increased in the three- and nine-month 2015 periods, compared with the same periods in 2014, due primarily to higher volumes delivered to the Overland Pass Pipeline from the Bakken NGL Pipeline.

Natural Gas Pipelines Segment

The natural gas pipelines segment experienced fairly normal operating conditions during the third quarter 2015. Variances in financial performance between the nine-month 2015 period and the same period in 2014 were primarily a reflection of significantly higher weather-related seasonal demand resulting in higher natural gas prices during the first quarter 2014.

Operating income increased for the third quarter 2015, compared with the same period in 2014, which primarily reflects:


    --  A $1.3 million increase due to higher storage revenues from increased
        rates; and
    --  A $1.2 million increase from higher transportation revenues, primarily
        from higher rates at Viking Gas Transmission Company.

The decrease in operating income for the nine-month 2015 period, compared with the same period in 2014, primarily reflects:


    --  A $12.6 million decrease from lower short-term natural gas storage
        services, due primarily to increased weather-related seasonal demand
        associated with severely cold weather in the first quarter 2014; and
    --  A $9.4 million decrease from lower net retained fuel due to lower
        natural gas prices and lower natural gas volumes retained; offset
        partially by
    --  A $5.8 million increase due to higher transportation revenues, primarily
        from increased rates on intrastate pipelines and higher rates at Viking
        Gas Transmission Company.

Operating costs decreased for the three- and nine-month 2015 periods, compared with the same periods in 2014, primarily as a result of lower costs for materials and supplies.

Equity in net earnings from investments increased for the three-month 2015 period, compared with the same period in 2014, due primarily to an increase in firm transportation on Northern Border Pipeline.

Equity in net earnings from investments decreased for the nine-month 2015 period, compared with the same period in 2014, due primarily to decreased natural gas park-and-loan services on Northern Border Pipeline, resulting from increased weather-related seasonal demand due to severely cold weather in the first quarter 2014, offset partially by an increase in firm transportation.

Natural Gas Gathering and Processing Segment

The natural gas gathering and processing segment's third-quarter and year-to-date 2015 results benefited from additional natural gas compression projects completed in 2015 and natural gas processing plants completed in 2014. For the nine-month 2015 period, natural gas gathered volumes increased approximately 13 percent and natural gas processed volumes increased approximately 12 percent, compared with the same period in 2014. Third-quarter natural gas volumes gathered increased slightly and natural gas volumes processed decreased slightly due to unplanned operational outages in the Williston Basin, which have been resolved, and minor timing delays in well completions in the Mid-Continent region.

Through the first nine months of 2015, the segment successfully restructured many of its percent-of-proceeds contracts to largely fee-based contracts and continues to actively work with its producer customers to similarly restructure additional contracts. Due to successful contract restructuring, the segment's third-quarter 2015 average fee rate increased nearly 20 percent, compared with the same period in 2014. The partnership expects the contract restructuring efforts in the Williston Basin to be substantially complete by the end of 2015 and to receive the benefit from improved margins in 2016. As a result, the segment's fee-based margin is expected to increase to more than 70 percent in 2016, compared with approximately 50 percent in 2015.

Third-quarter 2015 operating income, compared with the third quarter 2014, primarily reflects:


    --  A $53.9 million decrease due primarily to lower net realized NGL,
        natural gas and condensate prices; and
    --  A $7.0 million decrease due primarily to unplanned operational outages
        in the Williston Basin and decreased natural gas processed volumes in
        the Cana-Woodford Shale, offset partially by natural gas volume growth
        in the Williston Basin; offset partially by
    --  A $27.1 million increase due primarily to changes in contract mix
        resulting from higher fees.

Operating income for the nine-month 2015 period decreased, compared with the same period last year, which primarily reflects:


    --  A $153.3 million decrease due primarily to lower net realized NGL,
        natural gas and condensate prices; offset partially by
    --  A $47.9 million increase due primarily to changes in contract mix
        resulting from higher fees; and
    --  A $25.8 million increase due primarily to natural gas volume growth in
        the Williston Basin, offset partially by unplanned operational outages
        in the Williston Basin and decreased natural gas volumes in the
        Cana-Woodford Shale.

Operating costs decreased in the third quarter 2015 but increased overall through the first nine months of 2015, compared with the same periods in 2014. The decrease in the third quarter 2015 was due primarily to lower materials and supply costs due primarily to higher chemicals costs in the prior year. The increase in the nine-month 2015 period was due primarily to completed capital-growth projects.

Depreciation and amortization expense increased in the three- and nine-month 2015 periods, compared with the same periods in 2014, due primarily to completed capital-growth projects.

Equity in net earnings from investments increased for the three- and nine-month 2015 periods, compared with the same periods in 2014, due to a $76.4 million noncash impairment charge in the third quarter 2014 related to ONEOK Partners' equity investment in the Bighorn Gas Gathering system in the Powder River Basin.

The natural gas gathering and processing segment is exposed to commodity price risk as a result of percent-of-proceeds contracts, where the segment receives a percentage of volumes processed, or equity volumes, in exchange for services. ONEOK Partners expects NGLs, natural gas and crude oil commodity price sensitivity in the gathering and processing segment to decrease in 2016 as additional contracts are restructured to include higher fee-based components.

The partnership executes hedges to mitigate its commodity price risk. The tables below provide hedging information as of October 2015 for equity volumes in the natural gas gathering and processing segment in the periods indicated. NGLs hedged reflect propane, normal butane, iso-butane and natural gasoline only. The ethane component of the natural gas gathering and processing segment's equity NGL volume is not expected to significantly impact the results of operations.

2016 natural gas equity volumes are expected to be lower due to restructuring a significant portion of the segments' percent-of-proceed contracts. As a result, natural gas volumes hedged were realigned to reflect lower natural gas equity volumes expected in 2016.

All of the natural gas gathering and processing segment's commodity price sensitivities are estimated as a hypothetical change in the price of natural gas, NGLs and crude oil as of Sept. 30, 2015, excluding the effects of hedging and assuming normal operating conditions. Condensate sales are based on the price of crude oil.

The natural gas gathering and processing segment estimates the following sensitivities for the three months ending Dec. 31, 2015:


    --  A 10-cent-per-MMBtu change in the price of residue natural gas would
        change three-month net margin by approximately $1.2 million;
    --  A 1-cent-per-gallon change in the composite price of NGLs would change
        three-month net margin by approximately $0.8 million; and
    --  A $1.00-per-barrel change in the price of crude oil would change
        three-month net margin by approximately $0.3 million.

The natural gas gathering and processing segment estimates the following sensitivities for the year ending Dec. 31, 2016:


    --  A 10-cent-per-MMBtu change in the price of residue natural gas would
        change 12-month net margin by approximately $3.3 million;
    --  A 1-cent-per-gallon change in the composite price of NGLs would change
        12-month net margin by approximately $1.8 million; and
    --  A $1.00-per-barrel change in the price of crude oil would change
        12-month net margin by approximately $1.3 million.

These estimates do not include any effects on demand for ONEOK Partners' services or natural gas processing plant operations that might be caused by, or arise in conjunction with, price changes. For example, a change in the gross processing spread may cause a change in the amount of ethane extracted from the natural gas stream affecting natural gas gathering and processing margins for certain contracts.

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

ONEOK Partners has disclosed in this news release adjusted EBITDA, DCF, distributable cash flow to limited partners per limited partner unit and cash distribution coverage ratio, which are non-GAAP financial metrics, used to measure the partnership's financial performance and are defined as follows:


    --  Adjusted EBITDA is defined as net income adjusted for interest expense,
        depreciation and amortization, income taxes and allowance for equity
        funds used during construction and certain other items;
    --  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;
    --  Distributable cash flow to limited partners per limited partner unit is
        computed as DCF less distributions declared to the general partner in
        the period, divided by the weighted-average number of units outstanding
        in the period; and
    --  Cash distribution coverage ratio is defined as distributable cash flow
        to limited partners per limited partner unit divided by the distribution
        declared per limited partner unit for the period.

The partnership believes the non-GAAP financial measures described above are useful to investors because they are used by many companies in its industry to measure 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, DCF, distributable cash flow to limited partners and cash distribution coverage ratio per limited partner unit should not be considered alternatives 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 indicative of the actual amount of cash that is available for distributions or that is planned to be distributed in a given period, nor do they equate to available cash as defined in the partnership agreement.

        parent of our general partner;
