                Pioneer Provides Update to First Quarter Outlook,
                   Argentina Developments and Hedging Program

Dallas,  Texas,  April 9, 2002 -- Pioneer Natural Resources Company  ("Pioneer")
(NYSE:PXD)  (TSE:PXD)  today  updated its first  quarter 2002  outlook  based on
current  expectations  and  partial  quarter  actual  results,  outlined  recent
developments in Argentina and other areas of operation, and provided information
on the status of its hedging program.

First Quarter 2002 Outlook

The following  statements  are estimates  based on current  expectations.  These
forward-looking  statements  are subject to a number of risks and  uncertainties
that may cause the  Company's  actual  results  to  differ  materially  from the
following statements.  The last paragraph of this news release addresses certain
of the risks and uncertainties to which the Company is subject.

First  quarter  production  is expected to average  approximately  110  thousand
barrels per day on an oil equivalent basis. The Company's first quarter realized
price  for oil,  including  the  effects  of  hedges,  is  expected  to  average
approximately  $22.40 to $22.60 per barrel.  Pioneer's  first  quarter  realized
price for  natural  gas  liquids is  expected to range from $10.60 to $10.80 per
barrel.  The  Company's  first  quarter  realized  price for gas,  including the
effects of hedges, is expected to average  approximately $2.40 to $2.60 per Mcf.
First quarter lease  operating  expenses  (including  production  and ad valorem
taxes) are  expected  to  average  approximately  $5.05 to $5.25 per BOE.  Lease
operating  expenses are higher than  anticipated  principally  due to higher gas
prices,  which  impacted  field  fuel and  production  tax  expense,  and higher
workover  expenditures related to production  enhancement projects in Canada and
West Texas.  Depreciation,  depletion  and  amortization  expense is expected to
range from $5.00 to $5.20 per BOE. Total exploration and abandonment  expense is
expected to range from $20 million to $25  million.  General and  administrative
expense is expected to range from $11 million to $12 million.  Interest  expense
is expected to be  approximately  $26 million.  Cash taxes for the first quarter
are expected to be  approximately  $1 million  because the Company  continues to
benefit from the  carryforward of prior years' net operating  losses in the U.S.
and Canada. Capital expenditures are expected to range from $105 million to $115
million.

Argentina Developments

Pioneer  continues  to  monitor  the  political  and  economic   environment  in
Argentina,  where 17% of its oil, natural gas liquids and gas reserves were held
as of December 31, 2001.  During 2002, the government has continued to implement
reforms that are intended to stabilize the economy,  including the imposition of
a 20% tax on oil exports  beginning March 1, 2002. The Company  anticipates that
it will  resume oil  drilling  during  the third  quarter of 2002 as a result of
improved  oil  prices  and  reductions  in  drilling  costs and lease  operating
expenses.  The Company's oil and gas revenues will be reduced as a result of the
Argentine peso devaluation and recent export tax; however, the reduction will be
mitigated by decreases in the cost of Argentine operations and administration as
a result of the peso devaluation.

The  continuing  devaluation  of the Argentine  peso during the first quarter of
2002 will result in a noncash charge to results in that period of  approximately
$5 million to $7 million. The first quarter charge reflects the remeasurement of
the Company's  peso-denominated  monetary assets and liabilities to U.S. dollars
as of March 31, 2002. Once the exchange rate of Argentine pesos to U.S.  dollars
stabilizes, the impact of future remeasurement assessments should be minimal.

For the first quarter of 2002,  Pioneer's Argentine  subsidiaries  generated oil
and natural gas liquids revenues of  approximately  $15 million and gas revenues
of  approximately  $4  million.  During the same  three  months,  the  Argentine
subsidiaries incurred approximately $4 million of operating costs and $2 million






of  administrative  expenses.  During the first quarter of 2002, the Company has
exported approximately 75% of its Argentine oil production and approximately 15%
of its Argentine gas production.

Hedging Program

As a result of the recent increase in quoted future  commodity  prices,  Pioneer
has  aggressively  hedged its oil and gas production for the second half of 2002
and oil  production  for 2003 to  protect  its cash  flow and lock in  favorable
returns on  Pioneer's  new  production.  For 2002,  Pioneer has hedges  covering
approximately  80% of expected North American gas production at an average NYMEX
equivalent price of $3.85 per Mcf or greater and  approximately  65% of expected
worldwide  oil  production at an average  NYMEX  equivalent  price of $25.00 per
barrel or greater.  For 2003, Pioneer has oil hedges covering  approximately 25%
of expected  worldwide oil  production at an average NYMEX  equivalent  price of
$24.10 per barrel.  Pioneer's hedges are with a diverse group of intermediaries,
principally  large U.S. banks,  and are outlined in Item 9 of the Form 8-K filed
today with the Securities and Exchange Commission.

Other Press Releases

Pioneer  also issued press  releases  today  providing an update on  exploration
activities  and  announcing  acquisitions  totaling  $193  million  in the  West
Panhandle gas field in the Texas Panhandle and the Falcon field in the deepwater
Gulf of Mexico and  announcing  a public  offering  of 10 million  shares of its
common stock.
