                       UNION PACIFIC RESOURCES GROUP INC.
                     ANNOUNCES RECORD FIRST QUARTER VOLUMES

FORT WORTH, Texas -- Union Pacific Resources Group Inc. (NYSE - UPR) today
announced this year's first quarter average daily volumes from producing
properties increased 27 percent over the first quarter of 1997 to 2.05 billion
cubic feet equivalent per day (Bcfed). Volumes were especially strong because
production associated with the acquisition of Norcen Energy Resources, Ltd.
(Norcen) was included for the month of March. Also contributing to the volume
growth was the Company's Austin Chalk business unit, which had a record quarter,
producing 594 MMcfed, a 2.5 percent increase over the first quarter of 1997.

"Despite a tremendous amount of uncertainty related to commodity prices and
costs of services, we were still able to profitably grow the Company's volumes
in the first quarter," said Jack L. Messman, UPR's Chairman and CEO. "UPR's
success in the first quarter is directly related to the ability of our people to
adapt to the changing conditions in our industry."

UPR continued its growth through the drill bit by operating, on average, 49
drilling rigs per day. Norcen operated, on average, 23 rigs in March.

In addition to the 2.5 percent production increase in the Austin Chalk, several
other business units experienced significant production increases. The Gulf
Onshore/Offshore volumes were up 28 percent year over year on volumes of 150
million cubic feet equivalent per day (MMcfed) of natural gas, while East Texas
volumes were up 20 percent to 203 MMcfed year over year. South
Texas/Plains/Canada volumes increased 14 percent year over year with volumes
equaling 216 MMcfed.

Compared to the first quarter of 1997, discretionary cash flow decreased 17
percent to $265 million ($1.07 per share), while total revenues decreased 7
percent to $499 million. Discretionary cash flow contributed by Norcen was $20
million in March. Net income decreased to $31 million ($0.13 per share). Lower
commodity prices combined with purchase accounting and interest on the debt from
the Norcen acquisition were the primary reasons for the lower earnings. Price
realizations averaged $1.96 per thousand cubic feet equivalent (Mcfe) of natural
gas in the quarter, representing a 23 percent decrease from first quarter of
1997 prices, which equaled $2.55 per Mcfe. Purchase accounting for the Norcen
acquisition caused an increase in depreciation, depletion and amortization
(DD&A) expense of $20 million. Interest expense for the quarter rose to $39
million from $11 million for the same period last year.

The Austin Chalk business unit experienced volume growth due to the completion
of several new significant wells in the Deep Giddings area. The Cobb #1 well in
Washington County, Texas, was completed in February

and is producing at a sustained rate of approximately 50 MMcfd. Additionally,
the Goldberg #1 in Austin County, Texas, was completed in March and is producing
at a rate of 23 MMcfd. UPR has a 93 percent working interest in the Cobb well
and a 100 percent working interest in the Goldberg well. Currently, in the Deep
Giddings area, UPR is producing 170 MMcfd on a net basis and the Masters Creek
area of the Chalk is producing 130 MMcfed net. For the first quarter, the
Masters Creek volumes represent an increase of nearly 400 percent over first
quarter 1997.

In the Land Grant business unit, the Phosphoria 42-H well was completed in the
Brady field. It is currently producing 1,500 barrels of oil per day (BOPD) and
10.5 million cubic feet per day (MMcfd) of natural gas without stimulation. The
gas is flowing to the newly constructed Brady Sweetening Plant, which began
service in the first quarter. This plant will allow the Brady field, which has
recycled gas for the past 25 years to stimulate oil production, to begin
producing natural gas for sale.

OUTLOOK

The primary focus for the second quarter will be the implementation of a
deleveraging program, which is being initiated to strengthen the Company's
balance sheet.

"Our plan is to work quickly to reduce our debt level in order to achieve a
strong investment grade credit rating by the end of the year," Messman noted.
"We currently plan to accomplish this through a combination of reduced spending
and asset sales. We have reduced the combined 1998 capital budget of UPR and
Norcen by approximately $800 million to $1.3 billion. Spending for the combined
companies last year was approximately $2.5 billion, which includes approximately
$700 million for producing property and asset purchases. The revised spending
plans will reduce our rig count and our volumes from drilling, however, UPR
still anticipates increasing its volumes by 6 percent to 8 percent after
contemplated asset sales on a combined company, pro forma basis.

Union Pacific Resources is one of the nation's largest independent oil and gas
exploration and production companies. Based in Fort Worth, Texas, UPR has been
the #1 domestic driller for the past 6 years and is the #1 gas producer in the
state of Texas.

This press release, other than historical financial information, contains
forward looking statements that involve risks and uncertainties including
planned deleveraging and drilling activities, expected production efforts and
volumes and budgeted capital expenditures and other risks and uncertainties
detailed in the Company's SEC reports, including the report on Form 10-K for the
year ended December 31, 1997. Actual results may vary materially.
