                             RULE 12b-25 (b) AND (c)

     If the subject report could not be filed without unreasonable effort or

      |     could not be eliminated without unreasonable effort or expense;
      | (b) The subject annual report, semi-annual report, transition report

      |     portion thereof will be filed on or before the 15th calendar day

                                    PART III

     State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K,
10-Q, N-SAR, N-CSR or the transition report portion thereof could not be filed
within the prescribed time period.

          The Form 10-K of the registrant, BP Prudhoe Bay Royalty Trust (the
     "Trust"), could not be filed within the prescribed time period because the
     audited financial statements of the Trust and other information in the
     report dependant on the financial statements are not yet available.

          The Trust is administered by the corporate trust department of its
     Trustee, The Bank of New York. Due to the novelty of the requirements of
     Section 404 of the Sarbanes-Oxley Act of 2002, the Trustee engaged the
     services of a firm of independent consultants to conduct an evaluation of,
     and report on, the design effectiveness of the Trust's internal controls
     over financial reporting. The Trustee expects the consultants' report to be
     completed on or before March 31, 2005. The Trustee has been advised by KPMG
     LLP, the auditors of the Trust's financial statements, that they are unable
     to complete their audit of the financial statements until the consultants'
     evaluation has been completed.


                                     PART IV
                                OTHER INFORMATION

        (Name)                        (Area Code)   (Telephone Number)

     (2) Have all other periodic reports required under Section 13 or 15(d) of
the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act
of 1940 during the preceding 12 months or for such shorter period that the
registrant was required to file such report(s) been filed? If the answer is no,
identify report(s).

                                                              [X] Yes [ ] No

     (3) Is it anticipated that any significant change in results of operations
from the corresponding period for the last fiscal year will be reflected by the
earnings statements to be included in the subject report or portion thereof?

                                                              [ ] Yes [X] No

     If so: attach an explanation of the anticipated change, both narratively

BP Prudhoe Bay Royalty
Trust New York, New York

Ladies and Gentlemen:

Pursuant to Rule 12b-25 of the General Rules and Regulations under the
Securities Exchange Act of 1934, we inform you that we have been furnished a
copy of Form 12b-25, to be filed by BP Prudhoe Bay Royalty Trust (Trust) on or
about March 16, 2005, which contains notification of the registrant's inability
to file its Form 10-K by March 16, 2005. We have read the Trust's statements
contained in Part III therein and we agree with the stated reason as to why we
have been unable to complete our audit and report on the Trust's financial
statements for the year ended December 31, 2004, to be included in its Form

In connection with our audit of the financial statements of the Trust for the
year ended December 31, 2004, we requested that the trustee provide us with the
trustee's evaluation on the Trust's design of internal controls over financial
reporting as of December 31, 2004. We have been informed that the trustee has
not completed its evaluation of the design effectiveness of the Trust's internal
controls over financial reporting, and therefore, we have been unable to
complete our audit on the Trust's financial statements.

Very truly yours,



            KPMG LLP, a U.S. limited liability partnership is the US
