QUESTAR NET INCOME UP 49% IN SECOND-QUARTER 2006

Company Updates Estimates of Probable, Possible Reserves


SALT LAKE CITY — Questar Corp. (NYSE:STR) – a natural gas-focused energy company – grew net income 49% in the second quarter of 2006 to $90.4 million, or $1.03 per diluted share, compared to $60.7 million, or $0.70 per diluted share, for the second quarter of 2005. Net income growth was driven by higher natural gas production and higher realized prices for natural gas, oil and natural gas liquids (NGL) in the company’s exploration and production businesses. Second-quarter 2006 results included a $3.5 million or $0.04 per diluted share after-tax charge for unrealized mark-to-market losses on natural gas basis hedges and a $1.1 million or $0.01 per diluted share after-tax charge related to the redemption of $200 million of Questar Market Resources 7% Notes.


For the first half of 2006, Questar net income was $227.5 million, or $2.60 per diluted share, compared to $155.9 million or $1.79 per diluted share for the 2005 period, a 46% increase.

“All Questar operating units posted double-digit net income growth in the first half of 2006,” said Keith O. Rattie, Questar chairman, president and CEO. “But Questar E&P stands out. Questar E&P has now delivered year-on-year production growth of 15% or higher for four-straight quarters. Our veteran E&P team is getting the job done with the drill bit”.


SECOND-QUARTER HIGHLIGHTS


Questar E&P reported a 16% increase in natural gas, oil and NGL production volumes to 31.3 billion cubic feet of natural gas equivalent (Bcfe) compared to 26.9 Bcfe for the second quarter of 2005. Natural gas comprised 88% of reported volumes during the quarter.

Realized natural gas prices at Questar E&P rose 24% and realized crude oil and NGL prices rose 25%. Natural gas hedges increased reported revenues by $18.8 million while oil and NGL hedges reduced revenues by $6.7 million.

Unrealized mark-to-market losses on NYMEX/Rockies basis swaps reduced net income $3.5 million.

Wexpro’s investment base grew 17% to $220.1 million at June 30, 2006, compared to $188.0 million a year earlier. Wexpro produced 9.9 Bcfe during the second quarter on behalf of affiliate Questar Gas. Wexpro net income also benefited from 31% higher realized oil and NGL prices.

Questar Gas Management gas-processing volumes on a Btu basis increased 72% in the second quarter of 2006 to 26.5 million MMBtu compared to 15.4 million MMBtu for the year-earlier quarter. Gross gas-processing margin increased 53% to $10.3 million. Gas-gathering volumes and total gathering margin both rose 6% compared to the second quarter of 2005.

Questar Pipeline net income grew 30%, driven by new transportation contracts on its southern system in central Utah and on Overthrust Pipeline. Questar Pipeline also benefited from higher NGL volumes and realized NGL prices.

Questar ROA (Return on Assets, defined as earnings before interest and income taxes divided by average total assets) for the trailing 12-month period ended June 30, 2006, increased to 17.5%. Market Resources ROA was 23.0%, Questar Pipeline ROA was 9.0%, and Questar Gas ROA was 9.1%.


QUESTAR RAISES PRODUCTION GUIDANCE AND ADJUSTS FULL-YEAR EPS ESTIMATES TO REFLECT LOWER NATURAL GAS PRICES


The company now expects Questar E&P 2006 production to range from 126 to 128 Bcfe, up 2 Bcfe over the previous range. The revised production guidance – which excludes Wexpro – represents 10 to 12% growth over 2005 production of 114.2 Bcfe. Questar also adjusted its 2006 EPS guidance to reflect a significant decline in forward natural gas prices compared to the price levels assumed in previous guidance. The company now estimates that 2006 EPS will range from $4.50 - $4.70 per diluted share compared to previous guidance of $4.50 - $4.80 per diluted share. The company’s guidance excludes one-time items, assumes hedges in place on the date of this release, and assumes natural gas and oil prices and basis differentials as summarized in the following table:

Questar E&P has hedged about 69% of its forecast second-half 2006 natural gas and oil-equivalent production with fixed-price swaps. The company has hedged an additional 13% or 8.3 Bcf of forecast remaining 2006 production with NYMEX/Rockies basis-only swaps (see table at the end of this release).

The company estimates that a $1.00 per MMBtu change in the average NYMEX price of natural gas for the remainder of 2006 would result in about a $0.07 change in earnings per diluted share.

A $10.00 per barrel change in the average NYMEX price of oil for the remainder of 2006 would result in about a $0.02 change in earnings per diluted share.


Questar Market Resources Net Income Up 45% in Second Quarter, 56% for First-Half

Market Resources – which conducts natural gas and oil exploration, development and production, gas gathering and processing, wholesale gas and oil marketing and gas storage – reported net income of $79.3 million in the second quarter of 2006, up 45% from $54.8 million in the second quarter of 2005. For the first half of 2006, Market Resources net income increased 56% to $173.9 million.


Questar E&P Net Income Increases 63% in Second Quarter, 79% for First-Half

Market Resources subsidiary Questar E&P benefited from growing production and higher realized prices for the second quarter and first half of 2006. Questar E&P reported net income of $56.1 million in the second quarter, up 63% from $34.4 million in the 2005 period. Questar E&P production increased 16% to 31.3 Bcfe compared to 26.9 Bcfe in the 2005 quarter. Natural gas comprised about 88% of Questar E&P production in the 2006 period. For the first half of 2006, Questar E&P net income rose 79% to $126.6 million compared to $70.7 million a year earlier, driven by a 19% increase in production and higher realized natural gas, oil and NGL prices compared to the year-earlier period.

Average realized net-to-the-well natural gas prices at Questar E&P increased 24% in the second quarter of 2006 to $6.00 per thousand cubic feet (Mcf) compared to $4.82 per Mcf in the 2005 period. As summarized below, the increase was due to the positive impact of hedging in the current period. Questar E&P average realized oil and NGL price was $50.11 per barrel compared with $40.02 a year earlier, a 25% increase. Oil hedges decreased realized oil and NGL prices $10.80 per bbl in the second quarter of 2006. Unrealized mark-to-market losses on Rockies basis hedges reduced net income $3.5 million in the 2006 quarter.

Questar may hedge sales prices on up to 100% of forecast production from proved reserves to lock in acceptable returns on invested capital and to protect returns, cash flow and net income from a decline in commodity prices. During the second quarter of 2006, Questar E&P continued to take advantage of higher natural gas and oil prices to hedge additional future production. The company has and may continue to enter into basis-only hedges to protect cash flows and earnings from widening natural gas-price basis differentials that may result from capacity constraints on regional gas pipelines.


Questar E&P controllable production costs (the sum of depreciation, depletion and amortization expense, lease operating expense, general and administrative expense, and allocated interest expense) per unit of production increased 7% compared to the second quarter and the first half of 2005.

Depreciation, depletion and amortization expense increased due to higher costs for drilling, completion and related services, increased cost of steel casing, other tubulars and wellhead equipment, and the ongoing depletion of older, lower-cost reserves.

Per-unit lease operating expense decreased slightly as increased costs of materials and consumables were offset by higher production volumes.

Per-unit general and administrative expense decreased in the second quarter due primarily to reversal of an accrual related to a potential legal expense and higher production volumes. Absent the reversal, G&A would have been essentially flat with the year-earlier quarter.

Interest expense per unit increased in the 2006 quarter due to refinancing activities and a $50 million net increase in long-term debt during the quarter.


Questar E&P Updates Estimates of Probable, Possible Reserves


Questar E&P has recently completed an update of estimated probable and possible reserves associated with its Rocky Mountain and Midcontinent leaseholds. These estimates have been reviewed by the company’s independent reservoir engineers, having been prepared in accordance with the methodology and definitions detailed in the company’s March 8, 2005 news release, a copy of which can be obtained at:www.questar.com/news/2005_news/news_2005.html. Investors should note that these reserves are separate from and in addition to proved reserves included in our 2005 Annual Report and Form 10-K. The company cannot include information about unproved reserves in financial information filed with the Securities and Exchange Commission (SEC). In addition to Questar E&P year-end 2005 estimated proved reserves of 1,480 Bcfe, the company reported the following updated estimates of probable and possible reserves.

Rockies Legacy reserves include 210 probable and 478 possible Baxter/Frontier/Dakota locations in the Vermillion Basin and 143 probable and 183 possible Almond Formation locations in the Wamsutter area.

Midcontinent reserves include 220 probable and 24 possible locations in the Elm Grove area of northwest Louisiana and 22 probable and 3 possible locations in the Granite Wash play of the Texas Panhandle.

Wexpro reserves are not included in these estimates. The company reported Wexpro reserves of 521 Bcfe at year-end 2005.


Wexpro Net Income Up 14% in Second-Quarter, 15% in First-Half 2006

Wexpro – a Market Resources subsidiary that develops and produces cost-of-service reserves for Questar Gas – reported net income of $12.0 million in the current quarter, up 14% from the second quarter of 2005. Under a long-standing agreement with the states of Utah and Wyoming, Wexpro recovers its costs and earns an unlevered after-tax return of about 19 to 20% on its investment base – the investment in commercial wells and related facilities, adjusted for working capital and reduced for deferred income taxes and accumulated depreciation. Wexpro’s investment base at June 30, 2006, increased 17% to $220.1 million compared to $188.0 million a year earlier. Wexpro current-quarter net income also benefited from 31% higher realized oil and NGL prices. For the first half of 2006, Wexpro net income was $23.9 million compared to $20.7 million for the first half of 2005, a 15% increase. Wexpro first-half 2006 results benefited from 28% higher realized oil and NGL prices.


Gas Management Net Income Up 13% in Second-Quarter, 12% in First-Half 2006

Questar Gas Management (Gas Management) – Market Resources gas-gathering and processing-services business – grew net income 13% to $10.2 million in the second quarter of 2006. Gas Management results benefited from a 53% increase in gas-processing plant margin compared to the 2005 quarter. Gathering volumes were up 6% to 62.4 million MMBtu equivalent for the current quarter compared to 59.2 million MMBtu for the 2005 quarter driven by growing Questar E&P and third-party Pinedale production and new gathering and processing projects serving third parties in the Uinta Basin. For the first half of 2006, Gas Management net income increased 12% to $19.9 million compared to $17.8 million in the 2005 period, driven by higher volumes and improved margins in both gathering and processing.


Questar Pipeline Net Income Up 30% in Second-Quarter, 34% in First-Half 2006

Questar Pipeline – a subsidiary that provides interstate natural gas-transportation and storage services – reported net income of $9.9 million in the second quarter of 2006 compared to $7.6 million in the second quarter of 2005. Second-quarter results were driven by a $2.9 million increase in transportation revenues from recent system expansions and $1.7 million in higher NGL revenues. Questar Pipeline net income was $21.3 million in the first half of 2006 compared with $15.9 million a year ago. Net income rose 34%, driven by $6.4 million in higher transportation revenues from system expansions and $3.2 million higher NGL revenues. Operating, maintenance, general and administrative costs per decatherm transported decreased to $0.12 in the first half of 2006 from $0.14 in the first half of 2005.


Questar Gas Seasonal Net Loss Narrows in Second-Quarter, Net Income Up 13% in First-Half 2006

Questar Gas – which provides natural gas distribution services in Utah, Wyoming and Idaho – reported a seasonal loss of $0.7 million in the second quarter of 2006 compared with a loss of $3.4 million for the second quarter of 2005. Gross margin from natural gas sales increased $5.0 million over the prior year. The higher margin included an increase of $1.2 million from customer growth, $1.2 million from recovery of gas-processing costs, and $2.7 million from an adjustment to the estimate of unbilled revenues. In 2005, gas-processing costs of $1.2 million in the second quarter and $2.6 million in the first half were not recovered in rates until the fourth quarter pursuant to a Utah regulatory order. At June 30, 2006, Questar Gas served 836,000 customers, up 12,000 from the end of 2005. Temperature-adjusted usage per customer declined slightly from the year-earlier quarter. Questar Gas net income was $28.7 million in the first half of 2006 compared with $25.3 million during the same period of 2005, driven by customer growth and recovery of gas-processing costs.
