                       Pioneer Announces Drilling Results

Dallas,  Texas,  April 10, 2006 -- Pioneer Natural Resources Company  (NYSE:PXD)
provided an update  today on recent  drilling  activity  in the  Edwards  Trend,
Alaska and West Africa.

Edwards Trend

Pioneer has  accumulated  over 170,000 acres in the Edwards Trend - a tight gas,
proven  resource  play that  extends  over 250 miles  across  South  Texas.  The
Company's working interests (WI) range from 80% to 100%. Since 1999, Pioneer has
drilled  more  than 60  horizontal  wells in the trend  and  currently  produces
approximately 35 million cubic feet of gas per day (MMcfpd),  mostly from the 80
wells it operates  in the Pawnee  field.  The Company has over 20 new  prospects
identified and under lease within the trend. In 2006, the Company plans to drill
20 to 30 wells and test 10 to 15 of the new prospects.

Pioneer  currently has three rigs drilling in the play, with two additional rigs
scheduled  to arrive by July.  One more rig will arrive by year end, and one rig
is under contract for delivery in 2007.

To test its first new  prospect in the Edwards  Trend,  Pioneer has drilled four
wells which have  successfully  delineated a gas accumulation  spanning at least
six  miles.  The new  field is  similar  to the 300 Bcf  Pawnee  field  which is
approximately ten miles to the northeast.

The first well drilled,  the Schulz #1, tested at an initial rate of 2.8 MMcfpd,
and has stabilized  after six months of production at a rate of 1.3 MMcfpd.  The
Nichols #1 was drilled  four miles  southwest of the Schulz #1 and tested at 2.5
MMcfpd.  The Sinor Ranch #1 and Fulbright #1 were drilled  between the first two
wells and are being  completed.  All four  wells  found gas  columns of over 300
feet.

Pioneer  is  currently  preparing  a  development  plan for the new field and is
contracting  for a 150 square mile 3-D  seismic  survey to be  completed  during
2006. Development drilling is expected to begin later this year based on the new
seismic and well production data.

"We are very  encouraged with the early success in our Edwards Trend play," said
Scott Sheffield,  Pioneer's  Chairman and CEO. "We consistently drill horizontal
wells at Pawnee  for $3  million  to $3.5  million  per well and have a thorough
understanding of the Edwards geology. With the dominant acreage position we have
built over the last year and the rigs under  contract  to execute  our plan into
next year,  we expect to  replicate  our past success in this trend and steadily
grow our gas reserves and production through at least the end of this decade."

Alaska

The 2005 - 2006 winter drilling season program includes three  exploratory wells
in the Central  North  Slope area where  Pioneer  and its  partners  are testing
multiple play types which are close to existing infrastructure. Pioneer's Arctic
Fox  drilling  rig  is  being  utilized  for  the  three-well   program  and  is
demonstrating the efficiency of having a more mobile,  built-for-purpose  rig to
maximize  activity  during the short  winter-only  drilling  season on the North
Slope.







Pioneer  announced  in early  March  that  the  Hailstorm  #1 well  (50% WI) was
unsuccessful.  It was  drilled to test the first of  multiple  prospects  in the
153,000-acre  Pioneer-operated  Storms area just south of the giant  Prudhoe Bay
field.  ConocoPhillips  holds the remaining 50% working interest.  The Hailstorm
well  was  drilled  to a total  depth of 9,840  feet  and  found  non-commercial
hydrocarbons in the Ivishak formation. Additional prospects have been identified
in a variety  of  established  play  types and are likely to be tested in future
years.

The  Cronus  #1 well  (90% WI) was  planned  to test  multiple  objectives  on a
prospect just west of the Meltwater  field.  A Torok  sequence  similar to those
productive  at  Meltwater  was the  primary  objective  of the  well.  A  thick,
oil-bearing  sand  section  in the  Torok  and a thin,  oil-bearing  sand in the
Jurassic-aged  Kuparuk C were penetrated by the well. Wireline and core data are
currently  being  analyzed  and  integrated  with 3-D  seismic to  determine  if
appraisal  activities  are  warranted  during  the 2006 - 2007  winter  drilling
season.

Drilling on the Antigua Prospect (32% WI) is currently  underway.  This location
is immediately adjacent to the Kuparuk River field.  ConocoPhillips is operating
this well and has a 63% working interest.

West Africa

Pioneer  participated in the drilling of the Pina 1-X well on Block 256 (25% WI)
in the deepwater of Nigeria. The 631,000-acre block is operated by Devon Energy.
The well tested multiple objectives on a large thrust structure located near the
western edge of the block.  The well was drilled to a total depth of 16,645 feet
and found two non-commercial  gas reservoirs.  The partners plan to drill a well
in early 2007 to test a different play type.

Impact of Drilling Update on First Quarter 2006 Financial Results

In light of the above drilling update, the Company is now expecting  exploration
and abandonment  charges for the first quarter of 2006 to range from $80 million
to $90 million.  The first quarter  exploration and abandonment  charge includes
approximately  $40 million  attributable to drilling,  acreage and seismic costs
incurred in Nigeria.  The Nigerian charges are not currently deductible for U.S.
tax purposes;  consequently, the first quarter Nigerian charges will be the same
on both a pre-tax and after-tax basis.

In addition to the above exploration and abandonment  charges,  the Company will
recognize an incremental  pre-tax  charge in the first quarter of  approximately
$42 million ($26 million after-tax) related to updated  third-party bids for the
Company's  abandonment  obligation  for the East Cameron 322 field that was lost
during  Hurricane  Rita.  Insurance  is  expected  to cover  most of this  cost.
Insurance  recoveries  will be  recognized  as income in future  quarters as the
amount of the recoveries becomes known.
