                                 PROXY STATEMENT

                       2002 ANNUAL MEETING OF STOCKHOLDERS


        The board of directors of Pioneer Natural Resources Company  (the "Board
of Directors")  requests your Proxy for the Annual Meeting of Stockholders  that
will be held at 9:00 a.m., on Tuesday,  May 14, 2002, in the Britain Room at the
Dallas Marriott Las Colinas Hotel,  Irving,  Texas 75039 (the "Annual Meeting").
By granting the Proxy, you authorize the persons named on the Proxy to represent
you and vote your  shares at the  Annual  Meeting.  Those  persons  will also be
authorized  to vote your shares to adjourn the meeting  from time to time and to
vote your shares at any adjournments or postponements of the meeting.

        You may grant your Proxy by signing,  dating and returning  the enclosed
paper proxy card.  Instead of returning the paper proxy card, you may complete a
proxy card  electronically  through the Internet by accessing the website of the
Company's transfer agent at www.continentalstock.com.  You will need the control
numbers that are printed on your  personalized  paper proxy card.  See "Internet
Voting."

        If you attend the Annual Meeting, you may vote in person. If you are not
present at the Annual Meeting, your shares may be voted only by a person to whom
you have given a proper proxy,  such as the  accompanying  Proxy or the Internet
Proxy. You may revoke the Proxy in writing at any time before it is exercised at
the Annual  Meeting by  delivering  to the  Secretary  of the  Company a written
notice of the  revocation,  or by signing and delivering to the Secretary of the
Company a proxy  with a later  date or by  submitting  your vote  electronically
through the Internet with a later date.  Your  attendance at the Annual  Meeting
will not revoke the Proxy unless you give written  notice of  revocation  to the
Secretary  of the Company  before the Proxy is exercised or unless you vote your
shares in person at the Annual Meeting.

        This Proxy Statement and the  accompanying Notice of  Annual Meeting and
Proxy are first being  sent or given to stockholders of the Company on or about
April 10, 2002.

                                QUORUM AND VOTING

        Voting Stock. The Company has two outstanding classes of securities that
entitle  holders to vote  generally at meetings of the  Company's  stockholders:
common stock, par value $.01 per share; and Special  Preferred Voting Stock, par
value $.01 per share. A single share (the "Voting  Share") of Special  Preferred
Voting Stock was issued to Computershare Trust Company of Canada (the "Trustee")
as trustee  under a Voting  and  Exchange  Trust  Agreement  for the  benefit of
holders of exchangeable shares issued by the Company's wholly-owned  subsidiary,
Pioneer Natural Resources Canada Inc., in connection with the Company's December
1997 acquisition of Chauvco Resources Ltd. The common stock and the Voting Share
vote together as a single class on all matters except when Delaware law requires
otherwise. Each share of common stock outstanding on the record date is entitled
to one vote.  The Voting  Share is  entitled  to one vote for each  exchangeable
share outstanding on the record date. The Trustee is required to vote the Voting
Share in the manner that holders of exchangeable shares instruct, and to abstain
from voting in proportion to the exchangeable  shares for which the Trustee does
not receive  instructions.  Accordingly,  references to  "stockholders"  in this
Proxy  Statement  include holders of common stock,  the Trustee,  and holders of
exchangeable  shares.  The  procedures  for  holders of  exchangeable  shares to
instruct  the Trustee  about voting at the Annual  Meeting are  explained in the
"Information  Statement for Holders of  Exchangeable  Shares of Pioneer  Natural
Resources  Canada  Inc." that is  enclosed  with this Proxy  Statement  only for
holders of exchangeable shares.

                                        3





        Record Date.  The record date for stockholders entitled to notice of and
to vote at the Annual Meeting is the close of business on March 25, 2002. At the
record  date,  103,350,967  shares of common  stock and one  Voting  Share  were
outstanding and entitled to be voted at the Annual Meeting.  At the record date,
942,847  exchangeable  shares  were  outstanding  and  entitled  to give  voting
instructions to the Trustee.  Accordingly,  104,293,814 votes are eligible to be
cast at the Annual Meeting.

        Quorum and Adjournments.  The presence,  in person or by  proxy,  of the
holders of a majority of the votes  eligible to be cast at the Annual Meeting is
necessary to constitute a quorum at the Annual Meeting.

        If a quorum is not present,  the stockholders  entitled to  vote who are
present  in person or by proxy at the Annual  Meeting  have the power to adjourn
the Annual Meeting from time to time,  without notice other than an announcement
at the  Annual  Meeting,  until a quorum is  present.  At any  adjourned  Annual
Meeting at which a quorum is present,  any business may be transacted that might
have been transacted at the Annual Meeting as originally notified.

        Vote Required.  Directors will be  elected by a  plurality  of the votes
present and  entitled  to be voted at the Annual  Meeting.  Ratification  of the
selection of the  Company's  auditors will require the  affirmative  vote of the
holders of a majority  of the shares  present  and  entitled  to be voted at the
Annual  Meeting.   An  automated  system  that  the  Company's   transfer  agent
administers will tabulate the votes.  Brokers who hold shares in street name for
customers are required to vote shares in accordance with  instructions  received
from the beneficial owners. Brokers are permitted to vote on discretionary items
if they have not received  instructions from the beneficial owners, but they are
not permitted to vote (a "broker  non-vote") on  non-discretionary  items absent
instructions  from the beneficial  owner.  Abstentions and broker non-votes will
count in  determining  whether a quorum is present at the Annual  Meeting.  Both
abstentions  and broker  non-votes  will not have any  effect on the  outcome of
voting on director elections.  For purposes of voting on the ratification of the
selection  of  auditors,  abstentions  will be  included in the number of shares
voting  and will have the  effect of a vote  against  the  proposal,  and broker
non-votes will not be included in the number of shares voting and therefore will
have no effect on the outcome of the voting.

        Default Voting.  A Proxy that is properly completed and returned will be
voted at the Annual Meeting in accordance with the instructions on the Proxy. If
you  properly  complete  and return a Proxy,  but do not  indicate  any contrary
voting instructions, your shares will be voted as follows:

        o      FOR  the  election  of the  three  persons  named  in  this Proxy
               Statement as the Board of Directors' nominees for election to the
               Board of Directors.

        o      FOR the ratification of the selection of Ernst & Young LLP as the
               Company's auditors.

If any other  business properly comes  before the stockholders for a vote at the
meeting,  your shares will be voted in  accordance  with the  discretion  of the
holders of the Proxy.  The Board of  Directors  knows of no matters,  other than
those  previously  stated,  to be  presented  for  consideration  at the  Annual
Meeting.

                                    ITEM ONE

                              ELECTION OF DIRECTORS

        The Board of Directors has  nominated the following persons for election
as Class II  directors  of the Company  with their terms to expire at the annual
meeting of stockholders in 2005 when their successors are elected and qualified:

                               James R. Baroffio
                               Edison C. Buchanan
                               Scott D. Sheffield

        Messrs. Baroffio and Sheffield are currently serving as directors of the
Company,  and Mr.  Buchanan  is a new nominee to the Board of  Directors.  Their
biographical information is contained in "Directors and Executive Officers."

                                        4





        The Board of Directors has no reason to believe that any of its nominees
will be unable or unwilling to serve if elected.  If a nominee becomes unable or
unwilling to accept  nomination or election,  either the number of the Company's
directors  will be reduced or the persons  acting  under the Proxy will vote for
the election of a substitute nominee that the Board of Directors recommends.

        The  Board  of  Directors  recommends  that  stockholders  vote  FOR the
election of each of the nominees.

                                    ITEM TWO

                              SELECTION OF AUDITORS

        The Board of Directors has selected Ernst & Young LLP as the auditors of
the Company for 2002.  Ernst & Young LLP have  audited the  Company's  financial
statements since 1998. The 2001 audit was completed on January 25, 2002.

        Audit  Fees.  The  aggregate  fees  billed  by  Ernst &  Young  LLP  for
professional  services  rendered for the audit of the Company's annual financial
statements and reports on Forms 10-Q for 2001 were $482,078.

        Financial  Information  Systems  Design  and  Implementation  Fees.   No
services  were  performed by, and no fees were incurred to, Ernst & Young LLP in
connection with financial information systems design and implementation projects
for 2001.

        All Other Fees.  The aggregate  fees for all  other services rendered by
Ernst & Young LLP for 2001 were  $528,715,  comprised  of $385,000  for internal
audit services,  $40,830 for tax services,  and $102,885 for other  professional
services,  consisting  primarily of audit  related  services  associated  with a
securities registration.  Effective January 1, 2002, Ernst & Young LLP no longer
serves as the Company's internal audit services provider.

        The Company  expects that  representatives of  Ernst & Young LLP will be
present at the  Annual Meeting to respond to appropriate questions and to make a
statement if they desire to do so.

        The report of  Ernst & Young LLP on the  Company's  financial statements
for 2001,  2000 and 1999 did not contain an adverse  opinion or a disclaimer  of
opinion and was not qualified or modified as to uncertainty or audit scope.

        In connection with  the audits of the Company's financial statements for
2001, 2000 and 1999, there were no  disagreements  with Ernst & Young LLP on any
matters of accounting  principles or practices,  financial statement disclosure,
or auditing scope or procedures  which,  if not resolved to the  satisfaction of
such independent accountants,  would have caused such independent accountants to
make reference to the matter in their report.

        The  Board  of  Directors   recommends  that   stockholders   vote   FOR
ratification of the selection of Ernst & Young LLP.

Meeting.  In  accordance  with  the  Company's  bylaws,  the  existing  Board of

                      MEETINGS AND COMMITTEES OF DIRECTORS

        The Board of Directors of the  Company held 13 meetings during 2001.  No
director attended fewer than 75% of the total number of meetings of the Board of
Directors.  No director attended  fewer than 75% of the total number of meetings
of all committees of the Board of Directors on which that director served.

        The Board of Directors has two  standing committees: the Audit Committee
and the Compensation Committee.

        The members of the Audit Committee are Messrs. Houghton (Chair), Gardner
and Jones.  The Audit  Committee  held eight meetings  during 2001.  Information
regarding  the  functions  performed by the Audit  Committee is set forth in the
"Audit Committee Report" included in this annual proxy statement.

        The  Compensation  Committee  periodically  reviews  the   compensation,
employee  benefit  plans and fringe  benefits  paid to or provided for executive
officers of the  Company and  approves  the annual  salaries,  bonuses and stock
option  awards  of  the  Company's  executive  officers.   The  members  of  the
Compensation Committee are Messrs. Ramsey (Chairman) and Baroffio. The Committee
also  administers  the Company's  Long-Term  Incentive  Plan.  The  Compensation
Committee held three meetings during 2001.

                             MANAGEMENT COMPENSATION

Compensation of Directors

        Each non-employee director receives an annual retainer fee of $50,000 if
the  director  serves on a  committee  and  $40,000 if a director  does not.  In
addition, each non-employee director is reimbursed for travel expenses to attend
meetings of the Board of Directors or its  committees  and an additional  $2,500
for  services  as  chairman  of a  committee.  No  additional  fees are paid for
attendance at board or committee meetings. The Company's Chief Executive Officer
does not receive additional compensation for serving on the Board of Directors.

        Under the Company's Long-Term Incentive Plan, non-employee directors are
eligible to receive awards in the form of  non-qualified  stock  options,  stock
appreciation rights, restricted stock, or performance units. The Company can use
these awards  instead of cash to pay its  non-employee  directors all or part of
their  annual  retainer  fees.  The Board of Directors  determines  the form (or
combination  of forms) of  consideration  each year,  based on the  economic and
other  circumstances at the time and based on its view of which awards will best
align the interests of the stockholders and the directors.

        For the year following the  Company's 2001 annual stockholders' meeting,
the Board of Directors  were given a choice to be  compensated  in(a) 100% cash,
(b) 100% stock options, (c) 100% restricted stock, or (d) a combination of 50/50
of any two,  in payment of the  non-employee  directors'  annual  fees.  Messrs.
Baroffio,  Houghton,  Jones and Ramsey elected 100% cash  compensation,  and Mr.
Gardner elected to receive 100% of his compensation in stock options. The number
of shares  subject to stock options  granted to each  non-employee  director was
determined  by dividing the  director's  annual  retainer fee by the value of an
option for one share on May 16,  2001 (the last  closing  sale price  before the
date of the award). The options have a fair-market value exercise price, and the
value of each option was  calculated  using the  Black-Scholes  method  based on
assumptions  provided by the Company's executive  compensation  consulting firm.
These options  vested 25% each quarter with the first vesting date on August 31,
2001.

        On May 17, 2001, Mr. Gardner received an award of 4,878 stock options to
compensate  him for his annual  retainer fee (each stock  option  awarded has an
exercise price of $22.09).

        For the  year  following the  Company's  2002 annual  scheduled meeting,
Directors  can again  elect to receive  their  annual  fees 100% in cash,  stock
options  or  restricted  stock or 50% each in any two of  those  three  forms of
compensation.

                                        9

consists of base salaries,  annual bonuses, awards under the Long-Term Incentive
Plan,  contributions to the Company's 401(k)  retirement plan,  contributions to
the  Company's   deferred   compensation   retirement  plan,  and  miscellaneous

(a)  These  options  were  granted on  February  14,  2001,  vest at the rate of
     one-third each year, commencing on the first anniversary of the grant date,
     and have a term of five years from the date of  vesting.  The  Compensation
     Committee retains  discretion,  subject to Plan limits, to modify the terms
     of the  options.  In the event of a change in  control  of the  Company  as
     defined in the Plan, the options will  immediately  become fully vested and
     exercisable in full.

(b)  These  options  were  granted  on  August  14,  2001,  vest at the  rate of
     one-third each year commencing on the first  anniversary of the grant date,
     and have a term of five years from the date of  vesting.  The  Compensation
     Committee retains  discretion,  subject to Plan limits, to modify the terms
     of the  options.  In the event of a change in  control  of the  Company  as
     defined in the Plan, the options will  immediately  become fully vested and
     exercisable in full.

(c)  The  exercise  price per share is equal to the closing  price of the common
     stock on the New York Stock  Exchange  composite tape on the day before the
     date of grant.

(d)  The  estimated  grant  date  value of  shares in  footnotes  (a) and (b) is
     determined  using the  Black-Scholes  model.  The material  assumptions and
     adjustments incorporated in the Black-Scholes model in estimating the value
     of the options include the following:

          o    An interest rate of 4.12% for footnote (a) and 4.17% for footnote
               (b),  which  represents  the  interest  rate on a  U.S.  Treasury
               security  with a  maturity  date  corresponding  to the  expected
               option term.

          o    Volatility of 48.2% for footnote (a) and 50% for footnote and (b)
               calculated using  the lesser  of (1) daily  stock  prices for the
               120-day period prior to the grant date or (2) 50%.

     No other adjustments were made to the model for non-transferability or risk
     of forfeiture. The ultimate values of the options will depend on the future
     market price of the common stock,  which cannot be forecast with reasonable
     accuracy. The actual value,  if any, an optionee will realize upon exercise
     of an option will  depend on the  excess of the market  value of the common
     stock over the exercise price on the date the option is exercised.

(a)  Amounts were calculated by multiplying the number of unexercised options by
     $19.26,  which was the  closing sale  price of the common stock on December
     31, 2001, and subtracting the aggregate exercise price.


       Retirement  Plan.   The   Company  provides   a  non-qualified   deferred
compensation  retirement  plan for  officers  and certain key  employees  of the
Company. Each participant is allowed to contribute up to 25% of base salary. The
Company  provides  a  matching   contribution  of  100%  of  the   participant's
contribution limited to the first 10% of the officer's base salary (or 8% of the
key  employee's  base  salary).   The  Company   matching   contribution   vests
immediately.

       Severance  Agreements.  On  August  8,  1997,  the  Company  entered into
severance  agreements  with its  officers.  Salaries  and bonuses are set by the
Compensation  Committee  independent of these  agreements,  and the Compensation
Committee can increase or reduce base salaries at its discretion.

       Either the Company or the  officer may terminate the officer's employment
under the severance  agreement at any time.  The Company must pay the officer an
amount equal to one year's base salary if the officer's employment is terminated
because of death,  disability,  or normal  retirement.  The Company must pay the
officer an amount equal to one year's base salary and continue health  insurance
for the officer's  family for one year if the Company  terminates  the officer's
employment  without  cause  or if the  officer  terminates  employment  for good
reason,  which is when  reductions  in the  officer's  base annual salary exceed
specified limits or when the officer's  responsibilities have been significantly
reduced.  If within  one year  after a change in  control  of the  Company,  the
Company  terminates  the officer  without  cause,  or if the officer  terminates
employment for good reason,  the Company must pay the officer an amount equal to
2.99 times the sum of the  officer's  base salary plus target bonus for the year
and  continue  health  insurance  for the  officer's  family  for  three  years.
Additionally,  executive  officers have the right to purchase  health  insurance
from the acquiring  company until age 65 by paying  Consolidated  Omnibus Budget
Reconciliation Act of 1985 rates. If an officer  terminates  employment with the
Company  without  reason  between  six  months  and one year  after a change  in
control, or at any time within one year after a change in control if the officer
is  required  to move,  then the  Company  must pay the  officer one year's base
salary and continue  health  insurance  for the  officer's  family for one year.
Officers are also  entitled to additional  payments for certain tax  liabilities
that may apply to severance payments following a change in control.

        Indemnification Agreements. The Company has entered into indemnification
agreements  with  each  of its  directors  and  officers,  including  the  named
executive  officers.  Those  agreements  require  the Company to  indemnify  the
directors and officers to the fullest extent  permitted by the Delaware  General
Corporation  Law and to advance  expenses  in  connection  with  certain  claims
against  directors  and  officers.  The  Company  expects to enter into  similar
agreements  with persons  selected to be  directors  and officers in the future.
Each  indemnification  agreement also provides that, upon a potential  change in
control of the Company and if the  indemnified  director or officer so requests,
the Company will create a trust for the benefit of the  indemnified  director or
officer in an amount  sufficient to satisfy payment of all liabilities and suits
against which the Company has indemnified the director or officer.

           COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

       During fiscal  year 2001,  no member of the  Compensation  Committee also
served as an  executive officer of the  Company. During fiscal year 2001,  there
were no Compensation Committee interlocks with other companies.

             COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

       The  Compensation  Committee of   the  Board  of  Directors  submits  the
following  report  with  respect to the  executive  compensation  program of the
Company.

Compensation Principles and Philosophy

       The  overriding  responsibility  of  the  committee  is to  maintain  the
Company's  executive  compensation  program so that it  attracts  and  retains a
capable and highly motivated senior  management team and aligns the compensation
of the  Company's  executives  with the  Company's  strategic  business  plan to
increase  stockholder  value.  During 2001 the  committee  retained an executive
compensation  consulting  firm ("Hewitt  Associates") to assist and advise it in
its efforts to establish and administer  fair and competitive  compensation  and
incentive policies.  These policies emphasize variable  compensation,  structure
the annual bonus and long-term  incentive awards to be a significant  portion of
an  executive's  total  compensation  and result in total  compensation  that is
reflective  of Company  performance.  Stock  option  awards will  continue to be
emphasized as part of each executive's compensation package to align stockholder
and  executive  interests.  The  committee has adopted a policy of not repricing
stock  options  and  incorporated  that  policy  into  the  Company's  Long-Term
Incentive  Plan.  Other  critical  elements of the  Company's  compensation  and
incentive policies provide for:

      o    Base salaries at or slightly above median levels compared to industry
           industry survey information and peer group proxy analysis.

      o    Annual  target bonus  levels slightly  above medium with payouts that
           are based on both individual and Company performance.

      o    Long-term incentive award levels that are above median.

      o    Significant stock ownership by the  Directors and the Chief Executive
           Officer.

       To support the commitment to  significant  stock ownership, the Company's
current stock ownership guidelines are as follows:

      o    Non-employee  directors' stock value  equal to at  least three  times
           each director's annual retainer fee.

      o    Chairman of the Board and  Chief Executive Officer  stock value equal
           to at least five times base salary.

       In determining compliance with these guidelines,  the committee considers
its expectations of the  long-term value of the  Company's stock and the current
trading  levels.  Mr.  Sheffield  and all Directors are in  compliance  with the
ownership guidelines.

       The   Omnibus  Budget  Reconciliation  Act  of  1993  ("OBRA93")   placed
restrictions  on the  deductibility  of  executive  compensation  paid by public
companies.  Under the  restrictions  that were effective in 1994, the Company is
not able to deduct  compensation paid to any of the named executive  officers in
excess  of  $1,000,000   unless  the   compensation   meets  the  definition  of
"performance  based  compensation" in the legislation.  Non-deductibility  could
result in additional tax costs to the Company. While the committee cannot assess
with  certainty  how the  Company's  compensation  program  will  ultimately  be
affected by OBRA93, the committee  generally tries to preserve the deductibility
of all  executive  compensation  if it can do so  without  interfering  with the
Company's  ability to attract  and retain  capable and highly  motivated  senior
management.

                                       13





Elements of Compensation

       The elements  of the  compensation  program the committee administers for
executive  officers,  including  the Chief  Executive  Officer,  consist of base
salaries,  annual bonuses,  awards made under the Company's  Long-Term Incentive
Plan, contributions to the Company's 401(k) retirement plan, contributions to
the  Company's   deferred   compensation   retirement  plan,  and  miscellaneous
perquisites.   Base  salaries,  annual  bonuses  and  long-term  incentives  are
discussed  separately  below;  however,  the  committee  considers the aggregate
remuneration of executives when evaluating the executive compensation program.

       Base Salaries.  An executive's base salary is viewed as a fixed component
of total  compensation that should be competitive with companies of similar size
and business to the Company.  The  committee  has targeted  base  salaries at or
slightly  above the median  level for  companies of similar size and business to
the  Company.  The  committee  evaluates  the  base  salaries  of the  Company's
executive  officers on the basis of competitive base salary survey data provided
by  its   consultant   and   consideration   of  each   officer's   duties   and
responsibilities.  The  committee  views  the named  executives  below the Chief
Executive Officer level as a team with diverse duties but with similar authority
and  responsibility.  Hewitt  Associates  historically  has provided base salary
survey data on the majority of the Company's  peer group  companies,  a group of
independent exploration and production companies with similar asset, revenue and
capital  investment  profiles as the Company.  While the peer group  provided by
Hewitt  Associates  includes some of the members of the Dow Jones  Oil-Secondary
Index (the "DJ  Oil-Secondary  Group")  reflected in the  performance  graph set
forth  under  "Company  Performance"  below,  it  does  not  include  all of the
companies in that peer group and includes other companies with which the Company
competes.  The committee  determines  the base salary for all named  executives,
including Mr. Sheffield, using the same methodology.

       The  2001  base  salaries  for the  named  executive officers as a group,
including  Mr.  Sheffield,  were  identified  by Hewitt  Associates  as being at
approximately  the 50th percentile  level. For 2002 Mr.  Sheffield's base salary
was increased by 6% to $700,000 which Hewitt  Associates has identified as being
at or slightly above the 50th  percentile.  Hewitt  Associates has indicated the
other named  executive  officer's 2002 base salaries,  as a group,  are slightly
above the 50th percentile.

       Annual Bonuses.  Each year the committee  establishes a  target bonus for
each executive  based on the target bonus median levels of executives in similar
positions at peer group companies.  To maintain  internal  equity,  the level of
responsibility, scope and complexity of the executive's position are considered.
The range of awards for the annual  incentive bonus plan has  historically  been
between 75% to 150% of target.  For 2001 Hewitt Associates  determined the bonus
target levels for the named executive  officers were below the median levels for
peer group companies.  Each named executive's target bonus level,  including Mr.
Sheffield's,  was  increased to a level Hewitt  Associates  identified  as being
approximately  the 60th percentile  level.  Each named  executive's  2002 target
bonus level will be the same as their 2001 target bonus level.  In awarding 2001
bonuses,  the Company reviewed the following  criteria that are important to the
success of the Company's business plan.

                          o    Operating cost per BOE
                          o    Debt/Book capitalization
                          o    Reserve replacement
                          o    Growth of share value
                          o    Finding & development cost per BOE
                          o    Production growth
                          o    General and administrative costs

       In determining the  named executive  officers'  annual bonus awards,  the
committee also evaluated the Company's stock performance in relation to its peer
group. The committee did not employ a formula, specific targets or predetermined
weighting  of the above  financial  or  operational  performance  criteria.  The
committee  also evaluates  Company  performance in light of oil and gas industry
fundamentals and assesses how effectively management adapts to changing industry
conditions  and  opportunities  during  the year.  The  committee  observes  and
evaluates the individual  performance of executive officers through the year and
discusses the performance of these key executives with Mr. Sheffield.


                                       14





       For 2001,  the  committee  awarded  Mr.  Sheffield  and the  other  named
executives  cash  bonuses  above  the  target  bonus  levels.   Specific Company
performance which resulted in bonus payouts above target for 2001 included:

                          o    Base operating costs of $2.76 per BOE
                          o    Debt/Book capitalization of 55%
                          o    Reserve replacement of 208% (268% excluding price
                               revisions)
                          o    Return on equity of 9%
                          o    Finding and development costs of $7.49 per BOE
                                ($5.81 per BOE excluding price revisions)
                          o    General & administrative cost of $.89 per BOE

       Regarding stock performance,  for the second consecutive year,  Pioneer's
stock price performance compared to other peer group companies achieved a number
two ranking overall. Also, Pioneer's three year cumulative total return based on
stock price  performance  has exceeded both the S&P 500 and the DJ Oil Secondary
Group per the graph below.  In addition,  Pioneer's stock price hit a three year
high of $23.05 in May 2001.

       Long-term Incentives.  A  significant  portion  of  the  named  executive
officers' total compensation is comprised of long-term  incentive awards,  which
are intended to align executive  management's  interests in long-term growth and
success more  closely with the  interests  of the  Company's  stockholders.  The
committee has  determined  that annual stock option awards should be the primary
method to award  long-term  incentives.  To provide an averaging  effect for the
stock option exercise prices, the committee has elected to make semiannual stock
option awards of approximately 50% of annual grant levels.

       The number of options granted to  Mr. Sheffield in 2001 was determined by
a  comparison  of option  grants made to the Chief  Executive  Officer's of peer
group companies. The other named executive officers were reviewed as a team. The
level of options  awarded to each named  executive  was  determined by comparing
awards granted to peer company executives  holding similar positions,  and their
individual award levels were averaged to determine the actual grants.  The award
levels were not influenced by the stock holdings of the executives.  The Company
has historically  held to the  philosophy of  awarding long-term incentives that

                                       15





are above market  averages.  For 2001, Mr.  Sheffield was awarded  138,000 stock
options.  Hewitt Associates indicated the 2001 award levels placed Mr. Sheffield
and the  other  named  executives  at  slightly  above the 60th  percentile  for
long-term incentive awards among the survey group.

       In summary,  the Company  believes a  significant  portion  of  executive
compensation  should be variable and  performance-based  so that an  executive's
total  compensation is linked to the performance of the individual,  the Company
and its stock  price.  The  majority  of the  named  executive  officers'  total
compensation  is  variable,  at-risk  compensation.  This  structure  allows the
Company to  administer  overall  compensation  that rises or falls  based on the
Company's  performance  and to maintain a balance  between the Company's  short-
term and long-term objectives.

                             AUDIT COMMITTEE REPORT

       The Audit Committee's  purpose is to assist the Board of Directors in its
oversight of the Company's internal controls, financial statements and the audit
process. The Board of Directors,  in its business judgment,  has determined that
all members of the  committee  are  independent  as  required  under the listing
standards of the New York Stock Exchange.  The committee  operates pursuant to a
charter  adopted by the Board of Directors and published in the proxy  statement
for the annual meeting of stockholders in 2001.

       Management is responsible for the preparation, presentation and integrity
of the  Company's  financial  statements,  accounting  and  financial  reporting
principles,  and internal controls and procedures  designed to assure compliance
with accounting  standards and applicable laws and regulations.  The independent
auditors, Ernst & Young LLP, are responsible for performing an independent audit
of the consolidated  financial  statements in accordance with generally accepted
auditing standards.

       In  performing  its  oversight  role,  the  committee  has  reviewed  and
discussed the audited  financial  statements with management and the independent
auditors.  The committee has also  discussed with the  independent  auditors the
matters  required to be discussed by  Statement  on Auditing  Standards  No. 61,
Communication  with Audit Committees,  as currently in effect. The committee has
received the written  disclosures and the letter from the  independent  auditors
required by Independence  Standards Board Standard No. 1, Independent with Audit
Committees,  as currently in effect.  The committee has also considered  whether
the  performance  of other  non-audit  services by the  independent  auditors is
compatible with  maintaining the auditor's  independence  and has discussed with
the auditors the auditors' independence.

       Based on the  reports and  discussions  described  in  this  Report,  and
subject to the  limitations on the roles and  responsibilities  of the committee
referred to below and in the charter, the committee  recommended to the Board of
Directors that the audited financial statements be included in the Annual Report
on Form 10-K for the fiscal year ended  December 31,  2001,  for filing with the
Securities  and  Exchange  Commission.  The  committee  and the board  have also
recommended the selection of the Company's independent auditors.

       The members  of the  committee  are  not  professionally  engaged  in the
practice  of  auditing  or  accounting  for the  Company  and are not experts in
auditor   independence   standards.   Members  of  the  committee  rely  without
independent  verification  on  the  information  provided  to  them  and  on the
representations  made by management and the independent  auditors.  Accordingly,
the  committee's  oversight does not provide an  independent  basis to determine
that management has maintained  appropriate  accounting and financial  reporting
principles or appropriate  internal  controls and procedures  designed to assure
compliance  with  accounting  standards  and  applicable  laws and  regulations.
Furthermore, the committee's considerations and discussions referred to above do
not assure that the audit of the Company's financial statements has been carried
out in accordance with generally accepted auditing standards, that the financial
statements  are  presented in  accordance  with  generally  accepted  accounting
principles, or that Ernst & Young LLP is in fact independent.

       The following  graph and  chart  compare the  Company's  cumulative total
stockholder  return on common stock during the period from  December 31, 1996 to
December 31, 2001,  with  cumulative  total  stockholder  return during the same
period for the DJ Oil-Secondary  Group and the Standard and the Poor's 500 Index
as  prescribed  by  Securities  and Exchange  Commission  rules.  The  Company's
cumulative  total  stockholder  return for the period from  December 31, 1996 to
December  31, 2001  consists of Parker & Parsley's  operating  results  prior to
August 8, 1997 and the Company's operating results beginning August 8, 1997. The
graph and chart show the value, at December 31 in each of 1997, 1998, 1999, 2000
and 2001 of $100 invested at December 31, 1996, and assumes the  reinvestment of
all dividends.

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

       The executive  officers and directors of the Company are required to file
     reports with the SEC, and with the various Canadian  provincial  securities
commissions  (the "Canadian  Commissions"),  disclosing the amount and nature of
their  beneficial  ownership  in  common  stock,  as  well  as  changes  in that
ownership.  Pursuant to applicable Canadian policies, the executive officers and
directors  of the Company are  exempted  from filing  reports  with the Canadian
Commissions,  provided  that they timely  file all reports  required to be filed
with the SEC.

       Based solely  on its  review of  reports and written representations that
the Company has received,  the Company  believes that all required  reports were
filed on time for 2001.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

       Effective  January  1,  1999,  the  Company  entered into an  amended and
restated  agreement with  Rainwater,  Inc.,  whereby the Company pays Rainwater,
Inc.  $300,000 per year and reimburses  Rainwater,  Inc. for certain expenses in
consideration for certain consulting and financial analysis services provided to
the  Company  by  Rainwater,  Inc.  and its  representatives.  The  term of this
agreement expires on December 31, 2003.

                              STOCKHOLDER PROPOSALS

       Any stockholder  of the  Company who  desires  to  submit a  proposal for
action at the Company's  annual meeting of  stockholders  for 2003 and wishes to
have such proposal (a "Rule 14a-8  Proposal")  included in the  Company's  proxy
materials,  must submit such Rule 14a-8 Proposal to the Company at its principal
executive  offices no later than December 11, 2002,  unless the Company notifies
the  stockholders  otherwise.  Only those Rule 14a-8  Proposals  that are timely
received by the Company and proper for stockholder action (and otherwise proper)
will be included in the Company's proxy materials.

       Any  stockholder of the  Company who  desires to  submit a  proposal  for
action at the annual meeting of  stockholders in 2003, but does not wish to have
such  proposal  (a "Non-Rule  14a-8 Proposal") included  in the  Company's proxy

                                       20





materials,  must  submit  such  Non-Rule  14a-8  Proposal  to the Company at its
principal  executive offices no later than February 24, 2003, unless the Company
notifies  the  stockholders  otherwise.  If a  Non-Rule  14a-8  Proposal  is not
received by the Company on or before February 24, 2003, then the Company intends
to exercise its  discretionary  voting  authority  with respect to such Non-Rule
14a-8 Proposal.

       "Discretionary  voting  authority"  is the  ability to  vote proxies that
stockholders  have  executed  and  returned  to  the  Company,  on  matters  not
specifically   reflected  in  the  Company's  proxy  materials,   and  on  which
stockholders have not had an opportunity to vote by proxy.

       Stockholders  desiring  to  propose  action  at  the  annual  meeting  of
stockholders  must also comply with  Article  Ninth of the Amended and  Restated
Certificate of Incorporation of the Company.  Under Article Ninth, a stockholder
must submit to the Company,  no later than 60 days before the annual  meeting or
ten days  after  the  first  public  notice  of the  annual  meeting  is sent to
stockholders, a written notice setting forth (i) the nature of the proposal with
particularity,   including   the  written  text  of  the   proposal,   (ii)  the
stockholder's name, address and other personal  information,  (iii) any interest
of the  stockholder  in the  proposed  business,  (iv) the  name of any  persons
nominated to be elected or reelected as a director by the  stockholder,  and (v)
with  respect  to each such  nominee,  the  nominee's  name,  address  and other
personal information,  the number of shares of each class and series of stock of
the Company  held by such  nominee,  all  information  required to be  disclosed
pursuant to Regulation  14A of the  Securities  and Exchange Act of 1934,  and a
notarized letter containing such nominee's acceptance of the nomination, stating
his or her intention to serve as director if elected, and consenting to be named
as a nominee  in any proxy  statement  relating  to such  election.  The  person
presiding at the annual  meeting  will  determine  whether  business is properly
brought before the meeting and will not permit the consideration of any business
not properly brought before the meeting.

       Written requests  for inclusion  of any  stockholder  proposal  should be
addressed to Corporate Secretary,  Pioneer Natural Resources Company, 5205 North
O'Connor Boulevard,  Suite 1400, Irving,  Texas 75039. The Company suggests that
any such proposal be sent by certified mail, return receipt requested.

       The  Board  of  Directors   will  consider  any  nominee  recommended  by
stockholders  for election at the annual meeting of  stockholders  to be held in
2003 if that  nomination  is  submitted  in writing,  not later than January 10,
2003, to Corporate  Secretary,  Pioneer Natural  Resources  Company,  5205 North
O'Connor  Boulevard,  Suite 1400,  Irving,  Texas 75039.  Each  submission  must
include a statement of the  qualifications  of the nominee,  a notarized consent
signed by the  nominee  evidencing  a  willingness  to serve as a  director,  if
elected,  and a commitment by the nominee to meet personally with members of the
Board of Directors.

                             SOLICITATION OF PROXIES

       Solicitation  of  Proxies  may  be  made  by  mail,  personal  interview,
telephone  or  telegraph by  officers,  directors  and regular  employees of the
Company.  The Company may also request banking  institutions,  brokerage  firms,
custodians,  nominees and  fiduciaries to forward  solicitation  material to the
beneficial  owners of the common  stock that those  companies or persons hold of
record, and the Company will reimburse the forwarding expenses. In addition, the
Company has retained D.F. King & Co., Inc. to assist in  solicitation  for a fee
estimated not to exceed $7,500. The Company will bear all costs of solicitation.

                                STOCKHOLDER LIST

       In accordance with the Delaware General Corporation Law, the Company will
maintain at its corporate offices in Irving,  Texas,  a list of the stockholders
entitled to vote at the Annual Meeting. The list will be open to the examination
of any stockholder, for purposes germane to the Annual Meeting,  during ordinary
business hours for 10 days before the Annual Meeting.

                                  ANNUAL REPORT

December 31, 2001,  is being mailed to stockholders concurrently with this Proxy
Statement and does not form part of the proxy solicitation material.


                                       21





       Only a single copy of this Proxy Statement is being delivered to multiple
stockholders  sharing a common  address  unless the  Company  receives  contrary
instructions  from stockholders  sharing a common address.  Upon written or oral
request  to the  Company's  Investor  Relations  department  at the  address  or
telephone  number provided above,  the Company will deliver  promptly a separate
copy of the Proxy  Statement  to a  stockholder  at a shared  address to which a
single copy of this Proxy Statement was delivered. By written or oral request to
the same address,  (i) a stockholder  may direct a  notification  to the Company
that the  stockholder  wishes  to  receive  a  separate  annual  report or proxy
statement in the future,  or (ii)  stockholders who share an address and who are
receiving  delivery of multiple copies of the Company's  annual reports or proxy
statements  can request  delivery of only a single  copy of these  documents  to
their shared address.

       A copy  of the  Company's  Annual  Report on Form 10-K for the year ended
December  31,  2001,  as filed  with the  SEC,  will be sent to any  stockholder
without charge upon written  request  addressed to Investor  Relations,  Pioneer

            Information Statement for Holders of Exchangeable Shares
                                       of
                      Pioneer Natural Resources Canada Inc.

       The enclosed Proxy Statement and  related materials pertaining to Pioneer
Natural  Resources  Company  ("Pioneer")  have been  provided  to all holders of
Exchangeable  Shares of Pioneer Natural Resources Canada Inc. ("Pioneer Canada")
for the  purposes of  Pioneer's  annual  meeting of  stockholders  (the  "Annual
Meeting") to be held on May 14, 2002 at 9:00 a.m.  (Dallas,  Texas time), in the
Britain  Room at the Dallas  Marriott  Las Colinas  Hotel,  223 West Las Colinas
Blvd., Irving, Texas 75039. As a holder of Exchangeable Shares, you are entitled
to dividend and other rights  designed to be equivalent to the attributes of the
Common  Stock of Pioneer,  including  the right,  through a Voting and  Exchange
Trust  Agreement (the "Voting  Agreement"),  to attend and to vote at the Annual
Meeting. Given the attributes of the Exchangeable Shares, you will not receive a
Notice,  Information  Circular or Proxy for an annual meeting of shareholders of
Pioneer Canada, nor will a meeting of holders of Exchangeable Shares be held.

Exercise of Voting Rights

       Pursuant to the Voting Agreement,  Computershare Trust  Company of Canada
(the  "Trustee")  holds one share of special  preferred  voting stock of Pioneer
(the "Voting  Share") for the benefit of the holders (other than Pioneer and its
subsidiaries) of the Exchangeable  Shares.  The Voting Share carries a number of
votes,  exercisable at any meeting at which Pioneer stockholders are entitled to
vote  (including  the  Annual  Meeting),  equal  to the  number  of  outstanding
Exchangeable  Shares  (other than shares held by Pioneer and its  subsidiaries).
You are entitled to instruct  the Trustee to exercise one of the votes  attached
to the  Voting  Share  for each  Exchangeable  Share  you  hold,  or to grant to
Pioneer's  management  a proxy to  exercise  such votes in  accordance  with the
enclosed Proxy Statement.  Alternatively,  you may instruct the Trustee to grant
to you or your  designee  a proxy to attend the Annual  Meeting  and  personally
exercise your voting  rights.  For this  purpose,  the Trustee has furnished (or
caused  Pioneer to furnish) the enclosed  Proxy  Statement  and certain  related
materials to you as a holder of Exchangeable Shares.

       To instruct  the Trustee  as to  how you  want to  exercise  your  voting
rights, you must complete,  sign, date and return the enclosed form of direction
(the  "Direction")  to the Trustee by no later than 9:00 a.m.  (Calgary time) on
May 10,  2002 (the "Due  Time").  If the  Trustee  does not  receive  your fully
completed  Direction by the Due Time,  your voting rights will not be exercised.
You may revoke or amend your  instructions  to the Trustee (as indicated in your
Direction)  at any time up to and  including  the Due Time by  delivering to the
Trustee a written notice of revocation or by completing,  signing and delivering
to the  Trustee a new  Direction  bearing a later  date.  You may also revoke or
amend  your  instructions  in person at the  Annual  Meeting  prior to 9:00 a.m.
(Dallas,  Texas time) on May 14,  2002,  by  submitting  a written  amendment or
revocation of your  instructions and presenting  satisfactory  identification to
the  Trustee's  representatives  at the Annual  Meeting.  In either  case,  your
instructions of the later date will be binding on the Trustee.

General

       Pioneer  Canada and  certain of the  insiders  thereof have been exempted

such orders, Pioneer Canada is not required to prepare and file annual proxy and
related documentation,  quarterly reports, certain material change reports or an
