             BERRY PETROLEUM SIGNS DEVELOPMENT AGREEMENT
                  ON ADDITIONAL UINTA BASIN ACREAGE

Bakersfield,  CA  -  December  7,  2004  -  Berry  Petroleum  Company
(NYSE:BRY)   announced  a  Development  Agreement  with  Petro-Canada
Resources (USA) Inc., to develop Petro-Canada's Coyote Flats Prospect
in  the Uinta Basin in northeast Utah. Berry will be the operator and
upon  completing  a  defined  drilling  program,  will  own  50%   of
approximately  72,000  undeveloped acres. The Company  estimates  its
total  obligation  under  this agreement to  be  approximately  $10.3
million and will vary based on drilling costs.

Robert  Heinemann, president and chief executive officer,  said,  "We
are very pleased to partner with Petro-Canada on this opportunity  to
develop this acreage.  We are buying into one completed well  in  the
Ferron sand that has tested at over one million cubic feet (MMcf) per
day  of natural gas and is awaiting pipeline hook-up.  By the end  of
December  we intend to begin drilling the first of three  test  wells
into  the  Ferron  sand  to  a  depth of  approximately  7,500  feet.
Additionally,  we will drill a six-well Emery coalbed  methane  (CBM)
pilot,  which  is based on encouraging coal thickness encountered  in
the  drilling  of  the  earlier Ferron  well.  This  coal,  found  at
approximately  4,500  feet,  was  cored  and  has  potential  to   be
commercially successful. Upon the completion of this portion  of  the
drilling obligation, Berry will earn 50% in the subject property."

Michael  Duginski,  senior vice president of  corporate  development,
added,  "We  are  pleased  that we can add  this  highly  prospective
acreage  to  our  growing portfolio of assets in  the  Rockies.  This
acreage  is only 35 miles southwest of our Brundage Canyon  producing
asset  and  will  complement our asset base by adding both  potential
high-volume natural gas producing wells and long-lived gas production
through  the  CBM development. We paid $1.3 million  at  signing  and
expect  to  drill all of our obligation wells in 2005 for  around  $9
million, which will allow us to earn our interest in the acreage."

Berry Petroleum Company is a publicly traded independent oil and  gas
production   and  exploitation  company  with  its  headquarters   in
Bakersfield,  California and was ranked number 25 by Forbes  Magazine
on its 2004 "200 Best Small Companies" list.
