            Pioneer Announces Production Reinitiated at Devils Tower

Dallas,  Texas, November 4, 2004 -- Pioneer Natural Resources Company (NYSE:PXD)
today  announced  that  production  from the Devils  Tower field has returned to
pre-Hurricane  Ivan levels.  Three wells are currently  producing  approximately
28,000 barrels of oil equivalent per day on a gross basis,  and a fourth well is
expected to be producing by the end of November.

Eight  wells  have been  drilled  to  develop  the  field,  and,  as  previously
announced,  damage to the  platform  rig  sustained  during  Hurricane  Ivan has
delayed completion  activities related to the four remaining wells. However, the
timeframe for resuming  completion  activities has improved,  with potential for
continued field  development to begin by year end. The financial impact of these
delays is mitigated by business interruption  insurance coverage held by Pioneer
that is  designed  to restore the  expected  cash flow from the project  after a
waiting period that ended on November 1.

Pioneer  holds a 25% working  interest in the Devils Tower  field,  and Dominion
Exploration & Production, Inc., a subsidiary of Dominion (NYSE: D), operates the
field with a 75%  working  interest.  Devils  Tower is  located  about 140 miles
southeast of New Orleans on  Mississippi  Canyon block 773 in the deepwater Gulf
of Mexico.

"With  Devils  Tower  back on line,  Pioneer's  Gulf of  Mexico  production  has
returned  to  pre-hurricane  levels.  By the end of the  year,  we expect to add
deepwater  production from the fourth Devils Tower well,  resume production from
our  deepwater  Harrier  field in the Falcon  corridor  and exit 2004 with total
company production reaching record levels," stated Scott D. Sheffield, Pioneer's
Chairman and CEO.
