(1)	execute for and on behalf of the undersigned Forms 3, 4 and 5 (including
amendments thereto) in accordance with Section 16(a) of the Securities Exchange
Act of 1934 and the rules thereunder;

(2)	do and perform any and all acts for and on behalf of the undersigned that
may be necessary or desirable to complete and execute any such Form 3, 4 or 5
(including amendments thereto) and timely file that Form with the Securities and
Exchange Commission and any stock exchange, self-regulatory association or any
other authority; and

(3)	take any other action of any type whatsoever in connection with the
foregoing that, in the opinion of each such attorney-in-fact, may be of benefit
to, in the best interest of, or legally required of the undersigned, it being
understood that the documents executed by the attorney-in-fact on behalf of the
undersigned pursuant to this Power of Attorney shall be in such form and shall
contain such terms and conditions as the attorney-in-fact may approve in the
attorney-in-fact's discretion.

	The undersigned hereby grants to each such attorney-in-fact full power and
authority to do and perform all and every act and thing whatsoever requisite,
necessary or proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might or
could do if personally present, with full power of substitution or revocation,
hereby ratifying and confirming all that the attorney-in-fact, or the attorney-
in-fact's substitute or substitutes, shall lawfully do or cause to be done by
virtue of this Power of Attorney and the rights and powers herein granted. The
undersigned acknowledges that the foregoing attorneys-in-fact, and their
substitutes, in serving in such capacity at the request of the undersigned, are

Exchange Act of 1934.

	The undersigned agrees that each such attorney-in-fact may rely entirely
on information furnished orally or in writing by the undersigned to the

Pioneer Natural Resources Company and each such attorney-in-fact against any
losses, claims, damages or liabilities (or actions in these respects) that arise
out of or are based upon any untrue statements or omissions of necessary facts
in the information provided by the undersigned to such attorney-in fact for
purposes of executing, acknowledging, delivering or filing Form 3, 4 or 5
(including amendments thereto) and agrees to reimburse Pioneer Natural Resources
Company's and the attorney-in-fact on demand for any legal or other expenses
reasonably incurred in connection with investigating or defending against any
such loss, claim, damage, liability or action.

	This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4 and 5 with respect to the
undersigned's holdings of and transactions in securities issued by Pioneer
Natural Resources Company, unless earlier revoked by the undersigned in a signed
writing delivered to the foregoing attorneys in fact.

	IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to
be executed as of the date written below.
