Gentlemen:

     In  connection with the Annual Report on Form 10-K  for
the fiscal year ended December 31, 2003, (the Annual Report)
of  Berry Petroleum Company (the Company), we hereby consent
to  (i) the use of and reference to our report dated January
27, 2004, entitled "Appraisal Report as of December 31, 2003
on Certain Properties owned by Berry Petroleum Company," our
report  dated February 14, 2003, entitled "Appraisal  Report
as  of December 31, 2002 on Certain Property Interests owned
by  Berry  Petroleum Company," and our report dated February
25, 2002, entitled "Appraisal Report as of December 31, 2001
on  Certain  Property  Interests owned  by  Berry  Petroleum
Company," (collectively referred to as the "Reports"), under
the  caption "Oil and Gas Reserves" in items 1 and 2 of  the
Annual   Report   and   under  the   caption   "Supplemental
Information   About   Oil   &   Gas   Producing   Activities
(Unaudited)"  in item 8 of the Annual Report; and  (ii)  the
use of and reference to the name DeGolyer and MacNaughton as
the independent petroleum engineering firm that prepared the
Reports under such items; provided, however, that since  the
cash-flow   calculations  in  the  Annual   Report   include
estimated income taxes not included in the Reports,  we  are
unable to verify the accuracy of the cash-flow values in the
Annual Report.

                              Very truly yours,

                           /s/DeGOLYER and MacNAUGHTON
