                   Pioneer Reports Third Quarter 2002 Results

Dallas,   Texas,   October  24,  2002  --  Pioneer  Natural   Resources  Company
("Pioneer")(NYSE:PXD)  (TSE:PXD) today announced financial and operating results
for the quarter and nine months ended September 30, 2002.

Third Quarter Results

Pioneer reported a net loss of $.9 million,  or $0.01 per diluted share, for the
third  quarter of 2002.  Income as adjusted for several  unusual items was $15.0
million,  or $0.13 per share.  As previously  disclosed,  third quarter  results
included an extraordinary charge consisting of $15.6 million associated with the
repayment of a 20% interest-bearing  capital obligation associated with the West
Panhandle  acquisition and $3.9 million related to the  extinguishment of 9.625%
bonds. Third quarter results also included a $3.4 million gain on disposition of
assets and a $.2 million  noncash  gain on the  remeasurement  of the  Company's
Argentine  peso-denominated  net monetary assets. For the same period last year,
Pioneer reported net income of $24.6 million, or $0.25 per share. Income for the
2001 third quarter as adjusted for a $1.4 million  extraordinary gain related to
the early  extinguishment  of debt was $23.2 million,  or $0.24 per share.  Cash
flow from  operations  for the 2002 third quarter was $87.7 million  compared to
$122.9 million for the same period of 2001.

Third quarter oil sales  averaged  29,611  barrels per day (BPD) and natural gas
liquids sales averaged  22,693 BPD. Gas sales in the third quarter  averaged 385
million cubic feet per day  (MMcfpd).  On a barrel oil  equivalent  (BOE) basis,
total  sales  averaged  116,441  BPD.  Realized  prices for oil and  natural gas
liquids for the third  quarter were $21.77 and $14.10 per barrel,  respectively.
The realized price for gas was $2.25 per thousand  cubic feet (Mcf),  with North
American gas prices averaging $2.94 per Mcf.

Third  quarter  production  costs were reduced to $4.66 per BOE partially due to
cost  savings on  properties  associated  with the West  Panhandle  acquisition.
Exploration and abandonment costs of $18.3 million for the quarter included $8.5
million of geologic and  geophysical  expenses  including  seismic  costs,  $2.4
million of noncash  leasehold  abandonments  including  expired  leases and $7.4
million of exploration costs.

For the same  quarter  last  year,  Pioneer  reported  oil sales of 32,920  BPD,
natural  gas liquids  sales of 22,158 BPD and gas sales of 374 MMcfpd.  Realized
prices for the 2001 third  quarter  were  $25.06 per barrel for oil,  $15.01 per
barrel for natural gas liquids and $2.66 per Mcf for gas.

Nine Month Results

For the nine months ended  September  30, 2002,  Pioneer  reported net income of
$8.3  million,   or  $0.07  per  diluted   share.   Excluding  a  $22.3  million
extraordinary charge related to the early extinguishment of debt, a $7.7 million
noncash  charge for the  remeasurement  of the  Argentine  peso-denominated  net
monetary assets and a gain of $4.4 million on the disposition of assets,  income
as adjusted was $33.9 million or $0.30 per share. For the same period last year,
Pioneer reported net income of $120.9 million,  or $1.21 per share.  Excluding a
gain  of  $8.7  million  on  the  disposition  of  assets  and  a  $1.4  million
extraordinary  gain  related  to the  early  extinguishment  of debt,  income as
adjusted was $110.8  million or $1.11 per share.  Cash flow from  operations for
the nine-month period was $228.3 million compared to $390.0 million for the same
period in 2001.

Nine-month  oil sales  averaged  31,646 BPD and natural  gas liquids  sales were
22,007 BPD.  Gas sales were 352  MMcfpd.  On a BOE basis,  total sales  averaged
112,301 BPD.  Realized liquids prices for the 2002 nine-month period were $22.86
per barrel for oil and $13.17 per barrel for natural gas  liquids.  The realized
price for gas was $2.39 per Mcf, with North American gas prices  averaging $2.98
per Mcf. For the first nine months of 2001, Pioneer reported oil sales of 34,172
BPD,  natural  gas  liquids  sales of 21,383  BPD and gas  sales of 358  MMcfpd.
Realized prices for the 2001  nine-month  period were $24.95 per barrel for oil,
$18.87 per barrel for natural gas liquids and $3.40 per Mcf for gas.







Operational Update

In southern Tunisia, Pioneer has successfully tested two additional intervals in
the Adam exploration well on the Borj El Khadra permit. As previously announced,
the Adam 1 well  encountered  four oil and gas productive  zones in the Silurian
Acacus sand at a depth of approximately 3,000 meters. The primary zone tested at
approximately  3,500 BPD of 41 degree API oil,  while a secondary zone tested at
250 BPD. In two recent tests, a lower Acacus  interval  flowed up to 13.6 Mmcfpd
of gas with 1,320 BPD of condensate, and an upper Acacus interval flowed 899 BPD
of oil with 430 Mcfpd of gas. The four intervals tested at a combined total rate
of approximately 6,000 BPD of oil and condensate and 16 MMcfpd of gas.

Pioneer, through a wholly owned subsidiary, has a 40% interest in the well. AGIP
Tunisia BV, a wholly owned  subsidiary  of Eni, is operator with a 50% interest,
and Paladin Expro Limited has the remaining 10% interest. The Tunisian state oil
company,  ETAP, is carried through the  exploration  phase of activity and has a
right to back in for up to a 50% interest in any  development by reimbursing its
share of past expenditures from production revenues.  The field development plan
contemplates  connecting  production  from  the  Adam 1 well to  Eni's  existing
facilities  12  kilometers  southwest  of  the  location,  pending  partner  and
government approval. Pioneer is the third largest acreage holder onshore Tunisia
with permits covering approximately five million acres.

Pioneer today announced that it has signed an agreement with Armstrong Resources
to  acquire a 70%  working  interest  and  operatorship  in ten state  leases on
Alaska's North Slope.  The leases cover  approximately  14,000 acres between the
Kuparuk River unit and Thetis Island where Pioneer  expects to drill up to three
wells this winter.

Pioneer  announced  first  production   through  the  deepwater  Canyon  Express
gathering system on September 20, 2002. As a result of hurricanes in the Gulf of
Mexico,  the ramp-up of  production  from the project has been  delayed and full
production  is now expected in November.  The system is designed to handle up to
500 Mmcfpd.  Wells from  Aconcagua  and Camden Hills are now  producing  via the
multiple-field  gas  gathering  system.  The  project is  expected  to  increase
Pioneer's  worldwide  daily  production  by 15% to 20% compared to third quarter
2002 levels when it reaches full production rates.

The Company now expects  initial  production  from its Devils Tower field in the
deepwater  Gulf of Mexico to begin no earlier than late third  quarter 2003 as a
result of delays in the  construction of the truss spar  production  facilities.
First  production  from the Sable  field is now  expected in  mid-to-late  first
quarter  2003 as a result of delays in the upgrade of the  floating  production,
storage and offloading (FPSO) facilities.

As a result of the delays,  Pioneer now expects  2003  production  from its core
producing  areas  in the  U.S.,  Canada,  and  Argentina,  including  the  Big 4
projects,  to be nearer to the lower end of its  previously  announced  range of
165,000 to 180,000 BOE per day.  The  Company is  currently  evaluating  several
projects  for  inclusion  in its  2003  capital  budget  that  are  expected  to
supplement its 2003 production  forecast.  Pioneer's  recent Adam 1 discovery in
Tunisia is expected to impact 2003 production, and the Company plans to drill up
to six  additional  exploration  wells on  nearby  blocks,  of which  three  are
scheduled for early 2003. Pioneer plans to expand its North America  exploration
program in Canada during the coming winter  drilling season and plans to begin a
multi-well  program  on the Gulf of Mexico  shelf  later  this  year.  Pioneer's
production forecast does not include the potential for future core area property
acquisitions  that the Company  considers  complementary  to its development and
exploration growth strategy.

Development  of the  Pioneer-operated  deepwater  Falcon field is progressing on
schedule  with  minimal   impact  from   hurricane   evacuations.   Pioneer  has
successfully  drilled and is completing the two future  production  wells in the
Falcon  development  plan.  Within 30 days,  Pioneer  expects  to spud its first
Falcon  Corridor  exploration  prospect  for  potential  tie-in  to  the  Falcon
facilities  currently  under  development.  At least one additional  prospect is
expected to be spud in the area before year end.

Onshore,  Pioneer is currently  running five rigs in the Spraberry field, one in
the Pawnee field in South Texas and three in the West Panhandle field. There are
two rigs  active  in the Gulf of  Mexico  and four rigs  running  in  Argentina.
Pioneer  will begin its  winter-access  development  drilling  program in Canada
during the fourth quarter and hopes to spud its first exploration test within 30
days.

Scott D.  Sheffield,  Chairman  and CEO  stated,  "With the  start-up  of Canyon
Express,  we have entered a new phase in Pioneer's  growth plan.  With our other
three high-impact projects expected to come on production next year, 2003 should
be a great  year  for  Pioneer.  When the  last of our Big 4  projects  is fully







producing,  we expect  our daily  production  to be up 50% to 60% from  mid-2002
levels.  Projects in Gabon,  Tunisia and now Alaska give us the running  room to
meet our 10% to 15% annual production growth targets in 2004 through 2006."

Financial Outlook

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

Fourth quarter production is expected to average 118 to 124 MBPD on a BOE basis.
Included  in the  mid-point  of the  estimate  is 70 Mmcfpd net to Pioneer  from
Canyon  Express as the project  ramps up during the quarter to full  production.
Fourth quarter lease  operating  expenses  (including  production and ad valorem
taxes) are  expected  to average  $4.75 to $5.00 per BOE based on today's  NYMEX
strip  prices  for oil and gas.  Depreciation,  depletion  and  amortization  is
expected to average $5.50 to $5.75 per BOE. Total  exploration  and  abandonment
expense is expected to be $15 million to $30 million. General and administrative
expense  is  expected  to be  approximately  $13  million.  Interest  expense is
expected to be $23 million to $25 million and income taxes are expected to be $2
million  as the  Company  benefits  from the  carryforward  of prior  years' net
operating losses in the U.S. and Canada.

During the third quarter,  Pioneer added to its oil hedge  position.  Additional
volumes  of oil  were  hedged  for  2003 and  2004 at oil  prices  ranging  from
approximately $24 per barrel to $25 per barrel. The Company's oil and gas hedges
are  outlined  in Item 9 of the Form 8-K filed  today  with the  Securities  and
Exchange Commission.

     Discretionary cash flow and EBITDAX (as defined below) are presented herein
because of their wide acceptance as financial  indicators of a company's ability
to internally  fund  exploration  and  development  activities and to service or
incur debt.  Discretionary  cash flow and EBITDAX  should not be  considered  as
alternatives to net cash provided by operating activities,  net income (loss) or
income  (loss) from  continuing  operations,  as defined by  generally  accepted
accounting  principles.  Discretionary  cash flow and EBITDAX should also not be
considered as indicators of the Company's financial performance, as alternatives
to cash flow, as measures of liquidity or as being comparable to other similarly
titled measures of other companies.
