QUESTAR CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
June 30, 1998
(Unaudited)

Note 1 - Basis of Presentation

The interim financial statements furnished reflect all adjustments
which are, in the opinion of management, necessary for a fair
presentation of the results for the interim periods presented.  All
such adjustments are of a normal recurring nature.  Due to the
seasonal nature of the business, the results of operations for the
three- and six-month periods ended June 30, 1998 are not necessarily
indicative of the results that may be expected for the year ending
December 31, 1998.  For further information refer to the consolidated
financial statements and footnotes thereto included in the Company's
annual report on Form 10-K for the year ended December 31, 1997.


Note 2 - Planned Purchases of Gas and Oil Company and a Pipeline

A Questar subsidiary announced its intention, July 27, 1998,  to
acquire 100 percent of the common stock of HSRTW, Inc., a wholly
owned subsidiary of HS Resources, Inc. for $157.5 million, effective
September 1, 1998.  In the cash transaction, Universal Resources will
obtain an estimated 150 billion cubic feet equivalent of proved oil
and gas reserves primarily in Oklahoma, as well as in Texas, Arkansas
and Louisiana. The purchase price includes $155 million for gas and
oil reserves and other assets and $2.5 million for working capital.
Approximately 80 percent of the reserves are natural gas. The Company
plans to finance the purchase through short-term borrowings and an
expansion of its existing production-based credit facility.

On June 25, 1998 in an unrelated transaction another Questar
subsidiary announced its intention to acquire 700 miles of oil
pipeline from ARCO Pipe line Company. The purchase price of the line
is $40 million with financial closing expected on or about September
30, 1998.  The pipeline extends from northwestern New Mexico to Long
Beach, California.  Questar Pipeline will operate the pipeline once
it is modified to carry natural gas.  Reconditioning the pipe and
adding compression are scheduled to begin as soon as possible and
will continue for 18-24 months for an estimated total cost up to $60
million.  The project will be financed through short-term borrowings
until long-term debt can be issued.


Note 3 - Common Stock Split

In June 1998, Questar's common stock was split two shares for each
share outstanding.  Common stock disclosures, such as, earnings per
share, dividends per share and number of shares outstanding in the
prior period financial statements have been restated to reflect the
split.


Note 4 - Comprehensive Income

The Company adopted Statement of Financial Accounting Standards
(SFAS) No. 130 "Reporting Comprehensive Income" beginning January 1,
1998.  SFAS No. 130 establishes new rules for reporting comprehensive
income and its components.   However, the adoption of this statement
had no impact on Questar's net income and its shareholders' equity.
SFAS No. 130 requires unrealized gains or losses on
available-for-sale securities and foreign currency translation
adjustments to be included in other comprehensive income. Formerly,
these transactions were reported separately in shareholders' equity.
Prior year amounts have been reclassified to conform to the
requirements of SFAS No. 130.

Revenues from Market Resource operations were higher in the second
quarter of 1998 when compared with the second quarter of 1997 due
primarily to increased energy-marketing activities, particularly gas,
and higher gas production and prices.  Revenues were $68,335,000 or
23% lower in the first half of 1998 when compared to the prior year
period primarily the result of a 28% decrease in gas-marketing
volumes.  Energy marketing activities reported $368,000 of net income
in the first half of 1998 compared with a $945,000 loss in the first
half of 1997.

Gas production increased 2% in the first half of 1998 when compared
with the first half of 1997 and the average price increased 10%.  The
increase in production resulted from gas wells drilled in the Rocky
Mountain region in 1997.

Oil and NGL revenues were $10,755,000 lower in the first half
comparison due to a 30% drop in prices and a 9% decline in
production. The production decline was the result of the sale of
nonstrategic assets in 1997, normal production declines and a
temporary shutdown of the Brady processing plant due to a
construction project.

Market Resources hedged approximately 55% of its gas production
through June of 1999 with a price of about $2.10 per Mcf, net back to
the well.  Roughly 26% of its oil production was hedged at
approximately $16.90 per bbl for the remainder of 1998.  These
amounts include production volumes to be acquired from HS Resources.

Revenues for Questar Gas Management (QGM) decreased $8,335,000 or 39%
in the first half of 1998 compared with the same period in 1997 due
to a gathering contract revision and the sale of two processing
plants in 1997. Net income reported by QGM was $1,434,000 below last
year's income as a result of these factors and lower earnings from a
gas and NGL processing plant.

Revenues, less natural gas purchases, were $1,232,000 lower in the
second quarter of 1998 and $5,643,000 lower in the 6-month period
ended June 30, 1998 when compared with the same periods in 1997
because of several rate changes affecting the first half of 1998.  A
rate surcharge, associated with construction of a distribution
pipeline into southern Utah and in effect for the past 10 years, was
discontinued in September 1997.  Some general-service customers, who
met higher load factor standards, shifted to firm commercial rates,
which have a lower margin.  Retail usage of gas per customer fell
during the first half of 1998 after reaching an unusually high mark
in the first half of 1997. This is in large part attributable to
reaction to rising gas costs included in rates during the latter part
of 1997 and first part of 1998.

Partially offsetting the rate changes and lower usage per customer
has been the effect of a strong growth rate in the number of
customers served by Questar Gas.  The number of customers served grew
by 3.5% from a year ago to 643,696 at June 30, 1998.

Temperatures, as measured in degree days, were colder than normal in
the second quarter of 1998. However, the impact was slight because
temperatures are relatively mild during the second quarter in
comparison with the winter heating season that extends from November
through March.   Also, Questar Gas' rates include a
weather-normalization adjustment that reduces the revenue impact of
weather fluctuations.  Virtually all of Questar Gas' residential and
commercial volumes were covered under the weather-normalization
adjustment in the first half of both 1998 and 1997.

In March 1998, the Public Service Commission of Wyoming approved
Questar Gas' gas-merchant unbundling proposal that was filed in
Wyoming in 1997.  Under this plan, a transportation service option
was extended to residential and commercial customers as well as
industrial customers.  Customers choosing transportation service are
allowed to secure gas supplies directly from producers and marketers
and pay Questar Gas a fee for transportation services.  Questar Gas
continues to offer a traditional bundled sales service as well.  The
unbundling proposal called for an open enrollment period to be held
from March 1 through April 30.  However, no suppliers signed up to
provide gas to Wyoming customers.  Another open enrollment will be
held next year.  Questar expects that the option of unbundled service
in Wyoming will not have a material effect on earnings.

Volumes delivered to industrial customers increased 12% in the first
half of 1998 when compared with the same period of 1997 due to
additions of  new customers as well as expanded operations with
several ongoing customers.  Margins from gas delivered to industrial
customers are substantially lower than from gas delivered to
residential and commercial customers.

Questar Gas, as a result of acquiring Questar Pipeline's gas purchase
contracts, is responsible for any judgment rendered against Questar
Pipeline in a lawsuit that was tried before a jury in 1994.  In a
ruling issued June 2, 1998, the trial judge set aside all aspects of
the jury's verdict except for $.5 million in favor of a producer
related to certain contractual, take-or-pay issues.  Other than on
these take-or-pay matters, a judgment was entered on all other issues
in favor of Questar Pipeline.  A notice of appeal has been filed by
the producer.

Revenues were higher in the 3-, 6- and 12-month periods of 1998 due
primarily to increased firm-transportation and firm-storage
reservation charges.  Questar Pipeline expanded working gas capacity
by 5 Bcf at Clay Basin for a capital investment of $4 million.  The
expansion is expected to add about $3 million in annual storage
revenues.  Service began in the second quarter of 1998 and all new
capacity was committed to long-term contracts.

Income from unconsolidated affiliates in the 1998 periods include the
Company's share of earnings reported by TransColorado Gas
Transmission Co.  The noncash earnings reflect capitalization of
interest and equity costs (AFUDC) associated with the construction of
the TransColorado pipeline amounting to $405,000 in the 3-month
period, $723,000 in the 6-month period and $5,179,000 in the 12-month
period ended June 30, 1998.

Consolidated Results of Operations

Consolidated revenues were 18% higher in the second quarter ended
June 30, 1998 when compared with the second quarter of 1997 due to
increased revenues from energy-marketing and gas-distribution
activities.  Consolidated revenues were lower in the 6- and 12-month
periods ended June 30, 1998 when compared with the same periods of
1997 due primarily to decreased energy-marketing activities, oil
prices and oil production, which more than offset higher
gas-distribution revenues, gas production and gas prices during these
same reporting periods.

Natural gas and other product purchases were 60% higher in the second
quarter ended June 30, 1998 when compared with the second quarter of
1997 due to the increased cost, primarily of gas, purchased for
energy-marketing activities and higher gas costs recovered in
distribution rates.  Natural gas and other product purchases were
lower in the 6- and 12-month periods of 1998 due primarily to a
decrease in the quantity of gas purchased for energy-marketing
activities.

Increased labor-related costs for data processing caused a 4%
increase in operating and maintenance (O & M) expenses in the second
quarter of 1998 when compared with the same period in the prior year.
Cost-containment efforts, capitalizing labor costs associated with
construction projects and lower bad debt expenses in 1998 resulted in
lower O & M expenses in the 6- and 12-month periods of 1998.  The
Company continues efforts to resolve Year 2000 issues and expects
that the expense of becoming Year 2000 compliant will not be
material.  Depreciation expenses were lower in the 3- and 6- month
periods of 1998 when compared to the 1997 periods because of a lower
full-cost amortization rate and an adjustment associated with
transmission properties.  The full-cost amortization rate for
combined US and Canadian operations was $.83 per equivalent Mcf for
the first half of 1998 down from $.85 for the 1997 period.
Depreciation Other taxes, primarily production and property taxes,
were lower in the 6- and 12-month periods of 1998 because of lower
oil prices and production, and refunds and lower assessments of state
property taxes.

Eligible employees in the Company's Regulated Services group and in
Questar Energy Services, Inc., were offered an early retirement
program that was effective July 31, 1998.  Enhanced benefits will be
paid to 178 employees taking advantage of the offer.   The regulated
services work force was reduced by more than 10% or 177 employees,
which will decrease future operating expenses.  The Regulated
Services group will defer and amortize the costs associated with the
early retirement program over a five-year period in accordance with
past regulatory treatment.  The deferred annual charge is expected to
be more than offset by lower labor-related costs.

Interest and other income was higher in the 3- and 6-month periods of
1998 due primarily to a $5,727,000 pretax gain on an exchange of an
interest in Nextlink and $829,000 of interest earned on a
fiber-optics communications project with Nextlink.  In addition to
the items mentioned, higher pretax gains from selling Nextel shares
and increased earnings from unconsolidated affiliates resulted in an
increase in interest and other income reported in the 12-month period
ended June 30, 1998.

The effective income tax rate for the first six months was 32.1% in
1998 and 32.2% in 1997.  The Company recognized $4,246,000 of
production-related tax credits in the 1998 period and $4,917,000 in
the 1997 period.

Liquidity and Capital Resources

Operating Activities

Net cash provided from operating activities of $174,811,000 for the
first half of 1998 was $37,963,000 higher than was generated in the
same period of 1997.  The increase in cash flow resulted primarily
from collection of gas costs incurred by natural gas distribution
operations, which were under-collected in the first half of 1997.

Investing Activities

Financing Activities

In the first half of 1998 net cash flow provided from operating
activities was used to reduce short-term debt by $53,600,000 and
long-term debt by $38,638,000 and to fund capital expenditures.  The
Company intends to finance forecasted 1998 capital expenditures
through net cash provided from operating activities, bank borrowings
and issuing long-term debt.

Short-term borrowings, represented by commercial paper, amounted to
$77,600,000 at June 30, 1998 and $44,100,000 at June 30, 1997.  The
Company has short-term bank lines of credit, which serve as backup to
borrowings made under the commercial paper program.  The Company's
lines of credit borrowing capacity is $100 million April 1 through
September 30 to match seasonal-borrowing patterns. However, the
capacity is being expanded to $300 million for interim financing to
accommodate capital spending until long-term financing can be
arranged.
