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,  government  regulation or
action,  litigation,  the costs and  results of  drilling  and  operations,  the
Company's ability to replace reserves or implement its business plans, access to
and cost of capital,  uncertainties  about  estimates  of  reserves,  quality of
technical data, and environmental  risks. These and other risks are described in
the Company's 2000 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.

       Within this  Current Report on Form 8-K,  the following oil and gas terms
have  specific  meanings:  "Bbl"  means a  standard  barrel of 42 United  States
gallons;  "MMBtu"  means  one  million  British  thermal  units and is an energy
equivalent  measure of natural gas; "Mcf" means one thousand cubic feet and is a
measure  of natural  gas  volume;  and,  "NYMEX"  means The New York  Mercantile
Exchange.

       On January 9, 2002, the Company issued a news release updating its fourth
quarter 2001 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. The news release
is attached hereto as Exhibit 99.1 and incorporated by reference herein.

       The following table summarizes,  as of January 9, 2002, the Company's (i)
open oil hedge positions, (ii) open gas hedge positions and (iii) deferred gains
and  losses  on  terminated  commodity  hedges.  Deferred  gains  and  losses on
terminated  commodity hedges will be recognized as increases or decreases to oil
and gas  revenues  during  the  periods  in which  the  hedges  were  originally
scheduled to mature.
