Item 9.    Regulation FD Disclosure

       The information in this document includes forward-looking statements that
are made  pursuant  to the Safe  Harbor  Provisions  of the  Private  Securities
Litigation  Reform Act of 1995.  Forward-looking  statements,  and the  business
prospects of Pioneer Natural Resources Company (the "Company"), are subject to a
number of risks and  uncertainties  which may cause the Company's actual results
in future  periods to differ  materially  from the  forward-looking  statements.
These risks and uncertainties include, among other things, volatility of oil and
gas prices, product supply and demand, competition, international operations and
associated   international   political  and  economic  instability,   government
regulation  or  action,  litigation,  the  costs and  results  of  drilling  and
operations,  the Company's ability to replace  reserves,  implement its business
plans or complete its development  projects as scheduled,  access to and cost of
capital,  uncertainties about estimates of reserves,  quality of technical data,
environmental and weather risks, acts of war or terrorism. These and other risks
are described in the Company's Annual Report on Form 10-K and Quarterly  Reports
on Form 10-Q that are available  from the Company or the Securities and Exchange
Commission.

       On March 30,  2004,  the Company  issued a news  release that is attached
hereto as exhibit  99.1. In the news  release,  the Company  provided a guidance
update on first quarter production and exploration and abandonment expense based
on current  expectations  and partial quarter actual results;  announced  recent
drilling results,  including information regarding the Company's Juno and Myrtle
Beach prospects; and provided certain forward looking information, including the
acquisition of additional  interests in the Spraberry  field and timing of first
production  from the Company's  deepwater Gulf of Mexico Devils Tower,  Tomahawk
and Raptor fields.
