Operational Update

With most of the  capital  spending  on large  project  facilities  having  been
fulfilled  during 2002, a higher  percentage of the 2003 capital  budget will be
directed toward drilling  activities.  The Company plans to drill  approximately
450 wells during 2003,  up from 229 in 2002,  and plans to resume an  aggressive
development  drilling  program in its core  areas.  Pioneer  plans to double its
development activity,  drilling  approximately 150 wells in the Spraberry field,
130 wells in the West Panhandle and Hugoton fields,  ten wells in the Gulf Coast
area, 60 wells in Argentina and 40 wells in Canada.

The  Company has an active  exploration  program  planned for the first  quarter
including  continued  drilling in the  deepwater  Gulf of Mexico near its Falcon
field,  a deep gas  test on the  Gulf of  Mexico  shelf,  two to three  wells in
Alaska,  two to three wells in  Tunisia,  a well in South  Africa,  and up to 20
wells in Canada.





The Company is currently  running seven rigs in the Permian area,  three rigs in
the Gulf Coast area,  five rigs in the West Panhandle and Hugoton fields and one
rig in the Gulf of Mexico.  Three rigs are running in Argentina,  and Canada has
six rigs active in its winter-access development drilling program.

Scott D.  Sheffield,  Chairman and CEO stated,  "We're just  starting to see the
returns from our significant  past investments and the positive impact they will
have on Pioneer,  especially in today's strong commodity price  environment.  We
are  looking  forward to  significant  production  growth  this year and we have
visible  growth from existing  projects of 10 to 15% through 2004.  With the big
project  investments  essentially  behind  us, we plan to ramp up our  core-area
development  drilling  activity,  continue to appraise  existing  discoveries to
bring these  projects on line, and expand our  exploration  program in 2003. Our
focus is on extending this strong pace of production growth into the middle part
of the decade."

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.

First quarter 2003 production is expected to average 120,000 to 128,000 BOEs per
day.  Included in the mid-point of the estimate is 95 Mmcfpd net to Pioneer from
Canyon Express,  while current net production from the project is  approximately
109 Mmcfpd. First quarter lease operating expenses (including  production and ad
valorem  taxes) are expected to average  $5.10 to $5.40 per BOE based on today's
higher  NYMEX  strip  prices  for  oil  and  gas.  Depreciation,  depletion  and
amortization  is expected to average $5.75 to $6.00 per BOE.  Total  exploration
and  abandonment  expense is expected to be $20 million to $50  million,  as the
Company has several  exploration  wells  planned  for the  quarter.  General and
administrative  expense  is  expected  to be  approximately  $16  million to $17
million,   $2  to  $3  million  of  which   relates  to   estimated   additional
performance-based  compensation  costs.  Interest  expense is expected to be $24
million to $26 million and income taxes,  principally in Argentina, are expected
to be  approximately $2 million as the Company benefits from the carryforward of
net operating losses in the U.S. and Canada.

The Company's oil and gas hedges are outlined on the attached schedule.
