                                 ---------------


TO THE SHAREHOLDERS OF TRI-VALLEY CORPORATION:


               GENERAL INFORMATION ABOUT THE SHAREHOLDERS' MEETING
               ---------------------------------------------------

The  only  items  of business which management intends to present at the meeting
are  listed  in  the  Notice  of  Annual  Meeting  of  Shareholders.  This Proxy
Statement  provides  details  about  the  meeting.

The enclosed proxy material relating to Tri-Valley Corporation from our board of
directors  is sent to you as the direct or beneficial owner of our common stock,
with  our sincere request that you give those materials your prompt and thorough
consideration.  Your  vote  at  the  annual meeting is important to the Company.

The  Board of Directors of Tri-Valley Corporation hereby solicits your proxy (on
the  enclosed  proxy  form)  for use at our Annual Meeting of Shareholders to be
held  October  25, 2004, at 10:00 A.M. (local time) in the Mendocino Room of the
Embassy  Suites  Hotel-San  Francisco  Airport/Burlingame,  150  Anza  Blvd.,
Burlingame,  California  94010.

By  returning your signed proxy, you authorize management to vote your shares as
you  indicate  on  these items of business and to vote your shares in accordance
with  management's best judgment in response to proposals initiated by others at
the  meeting.

Our  administrative  office is located at 5555 Business Park South, Bakersfield,
California  93309.  The approximate date on which this Proxy Statement and proxy
will first be sent to the shareholders is September 10, 2004.  The costs of this
proxy  notification  will  be  paid  by  the  company  and  are  estimated to be
approximately  $7,000.  A  professional  proxy  solicitor  has not been engaged.

IF  YOU  ARE  UNABLE  TO  ATTEND  THIS  MEETING,  WE REQUEST THAT YOU RETURN THE
ENCLOSED  PROXY  FORM,  PROPERLY  EXECUTED,  IN  ORDER  THAT YOUR SHARES WILL BE
REPRESENTED  AND  VOTED  AT  THE  MEETING.

CHANGING OR REVOKING YOUR PROXY VOTE

You  may  revoke  your  signed  proxy  at any time before it is exercised at the
annual  meeting.  You  may  do this by advising our secretary in writing of your
desire  to  revoke  your proxy, or by submitting a duly executed proxy bearing a
later  date.  We  will  honor the proxy card with the latest date.  You may also
revoke  your  proxy by attending the annual meeting and indicating that you wish
to  vote  in  person.



WHO MAY VOTE

As  of  July  31,  2004, 20,568,127 shares of our common stock were outstanding.
Each share is entitled to one vote per director in the election of directors and
one  vote in all other matters to be voted upon at the meeting.  SHAREHOLDERS OF
RECORD  AS  OF THE CLOSE OF BUSINESS AT 5:00 P.M. ON FRIDAY, SEPTEMBER 10, 2004,
ARE  THE  ONLY  PERSONS  ENTITLED  TO  VOTE  AT  THIS  MEETING.

VOTING IN PERSON

Although  we encourage you to complete and return your proxy to ensure that your
vote  is  counted,  you  can  attend  the annual meeting and vote your shares in
person.

HOW YOUR VOTES ARE COUNTED

We  will  hold  the  annual  meeting  if  holders  of not less than one-half the
outstanding  shares  are  present either in person or by proxy.  If you sign and
return your proxy card, your shares will be counted to determine whether we have
a quorum even if you abstain or fail to vote on any of the matters listed on the
proxy  card.

The  vote  of  a  majority of the shares present at the meeting, in person or by
proxy,  is  necessary  to  elect  directors.

ABSTAINING IS THE SAME AS VOTING "NO"

If  you  mark  "Abstain" with respect to any proposal on your proxy, your shares
will  be  counted in the number of votes cast.  HOWEVER, A VOTE TO "ABSTAIN" HAS
THE SAME EFFECT AS VOTING NO.  MANAGEMENT REQUESTS THAT YOU VOTE EITHER "FOR" OR
"AGAINST"  ON  EACH  PROPOSAL  TO COME BEFORE THE MEETING.  If a broker or other
nominee  holding  shares for a beneficial owner does not vote on a proposal, the
shares  will  not  be  counted  in  the  number  of  votes  cast.

A  ''broker  non-vote''  occurs when your broker submits a proxy for your shares
but  does  not indicate a vote for a particular proposal because the broker does
not  have  authority  to  vote  on  that  proposal  and  has not received voting
instructions from you. ''Broker non-votes'' are not counted as votes against the
proposal  in  question  or as abstentions, nor are they counted to determine the
number  of  votes  present  for  the  particular  proposal.


                                ITEMS OF BUSINESS
                                -----------------

--------------------------------------------------------------------------------
PROPOSAL 1:     ELECTION OF DIRECTORS
--------------------------------------------------------------------------------

The Board of Directors consists of six (6) members.  Each director serves for a
term of one (1) year.  All six (6) director positions are up for election at the
meeting.


                                        3

VOTING

The six nominees receiving the highest number of votes will be elected.  Proxies
solicited  by  the  board  of  directors  will be voted in favor of each nominee
unless  shareholders  specify  otherwise  in  their  proxies.  Should any of the
nominees  become  unavailable at the time of the meeting to accept nomination or
election  as a director, the proxy holders named in the enclosed proxy will vote
for  substitute  nominees at their discretion. Votes withheld for a nominee will
not  be  counted.

CUMULATIVE VOTING

Although  we  are  incorporated  in Delaware, we currently maintain our business
offices  and  principal  oil  and  gas  operations  in California.  Accordingly,
shareholders  are  entitled,  under  California  corporation  law, to cumulative
voting  rights  in the election of directors.  This means that a shareholder may
multiply  the  shares  held by the total number of directors to be elected (six)
and vote all of such shares for any one director.  Prior to the meeting and vote
on  directors, any shareholder wishing to exercise cumulative voting rights must
give  the  company  written  notice  of  exercise  of  cumulative voting rights.
Discretionary  authority  to cumulate votes in the exercise of proxies is hereby
solicited  by  management.

NOMINEES FOR THE BOARD OF DIRECTORS

--------------------------------------------------------------------------------
THE  BOARD  OF  DIRECTORS  RECOMMENDS  A  VOTE  FOR  THE ELECTION OF EACH OF THE
FOLLOWING  SIX  NOMINEES  FOR  DIRECTOR.

EACH  DIRECTOR  MUST  BE ELECTED BY A MAJORITY VOTE OF THE SHARES REPRESENTED AT
THE  MEETING.

Compensation Committee


Members:   C.  Chase  Hoffman  (Chair)
-------    Harold  J.  Noyes


Meetings  held  to  review  personnel  and  compensation  -  one.

Audit  Committee  -  The  Corporation has had independent director review of its
financial  reports  since  1981.

Purpose:  The  audit  committee provides an open avenue of communication between
-------
          our  independent  auditor,  the  company  officers  and  the  board of
          directors.  The committee operates under a charter that sets forth the
          committee's  tasks.  The  chief  duties  of  the  committee  are:

          -    Assure  the  independence  and  objectivity of the auditing firm.
          -    Review  and  coordinate  the  auditing  responsibilities with the
               auditor  and  chief  financial  officer.
          -    Review  the  adequacy  of  internal  accounting  controls.
          -    Inquire about significant risks and about management's actions to
               minimize  risks.
          -    Review  significant  audit  findings  and  any  difficulties
               encountered  in  conducting  the  audit.

Members:    Loren  J.  Miller,  CPA  (Chair)
-------
            Dennis  P.  Lockhart

          The  committee charter requires the audit committee to be comprised of
          at  least  three members, who must be independent members of our board
          of  directors.  The  qualifications  of  members  and  standards  for
          determining  who is an "independent" director conform to the standards
          set  forth  in the Nasdaq Stock Market's rules for companies quoted on
          Nasdaq.  All  audit  committee  members  must  be  able  to  read  and
          understand fundamental financial statements or to become able to do so
          shortly  after  joining  the  committee. At least one member must have
          previous  employment  in  accounting  or  finance,  certification  in
          accounting  or  comparable  experience.  Our  current  audit committee
          members  meet  these  requirements.  Mr.  Miller is a certified public
          accountant.

Audit  Committee  Report:
------------------------

          The  audit  committee has reviewed and discussed the audited financial
          statements  with  management  as  well  as  our  independent  public
          accountants.  The  audit  committee  has received from the independent
          accountants  a  formal  written  statement  regarding  the  auditors'
          independence and has discussed with the independent accountant matters
          relating  to  their  independence.  The  audit  committee members have
          satisfied  themselves  as  to  the  auditors'  independence. The audit
          committee  has  discussed with the independent accountants the matters
          required  to  be  discussed by Statement on Auditing Standards No. 61,
          which includes, among other items, matters related to the audit of our
          financial  statements.

          The audit committee has recommended to the board of directors that the
          audited  financial  statements  be  included  in  the company's Annual
          Report  on  Form  10-K  for  2003  for  filing with the Securities and

*Based  on  a  fair  market  value of $4.40 per share, which was the closing bid
price  of  our common stock on the American Stock Exchange on December 31, 2003.

Compensation  Committee  Report

Mr. Blystone's compensation is paid pursuant to the provisions of his employment
contract,  which  had  a  primary  period  ending  in December 2002 and which is
extendable for three consecutive annual periods through December 2005.  The base
salary  amount  is $99,000 per year plus 5,000 shares of our common stock at the
end  of  each year of service.  Mr. Blystone is also entitled to a bonus (not to
exceed  $25,000) equal to 10% of net operating cash flow before taxes, including
interest  income and excluding debt service.  Mr. Blystone is also entitled to a
bonus  of  4%  of  the  company's  annual net after-tax income. The total of the
bonuses  from  cash  flow  and  net  income  may  not  exceed  $50,000 per year.

Because  of  the relatively small size of the staff of Tri-Valley, which permits
the board and compensation committee to evaluate the performance of Mr. Blystone
and the remaining officers in detail, the compensation committee has not adopted
quantitative  performance  measures  to


                                        9

review  performance,  award  bonuses  and  adjust compensation, other than those
contained  in  Mr.  Blystone's  employment  contract  and noted in the preceding
paragraph.  Based  on  the  performance of Tri-Valley in 2003, the board awarded
Mr. Blystone the maximum $50,000 bonus that is permitted under his contract.  In
making  this award, the board and compensation committee considered not only Mr.
Blystone's  performance  during  2003  but  also his continued dedication to the
company  over  the  past  several  years.

The employment agreement also provides a severance payment to Mr. Blystone if he
is  terminated  within  12  months  after  a sale of control of Tri-Valley.  The
severance  payment  equals $150,000.  In addition, Mr. Blystone is entitled to a
bonus  equal to 10% of net operating  cash flow before taxes, including interest
income and excluding debt service, plus 4% of the company's annual net after-tax
income,  up to a maximum of $50,000 (with the maximum amount pro-rated over  the
period for which the payment is made).  For purposes of the severance provision,
a  sale  of  control  is  deemed  to  be  the  sale  of  ownership of 30% of our
outstanding  stock or the acquisition by one person of enough stock to appoint a
majority  of  the  board  of  directors  of  the  company.

Performance Graph

The  following  stock price performance graph is included in accordance with the
SEC's  executive  compensation  disclosure  rules  and  is  intended  to  allow
stockholders  to  review  our  executive  compensation  policies  in  light  of
corresponding stockholder returns, expressed in terms of the appreciation of our
common  stock  relative  to  two  broad-based  stock  performance  indices.  The
information  is included for historical comparative purposes only and should not
be  considered  indicative  of  future stock performance. The graph compares the
yearly  percentage  change  in  the  cumulative  total stockholder return on our
common  stock  with the cumulative total return of Royale Energy, Inc., Parallel
Petroleum  Corporation  and  Equity  Oil  Company from December 31, 1999 through
December  31,  2003.

Total  returns assume $100 invested on December 31, 1999 in shares of Tri-Valley
Corporation,  Royale Energy Inc., Parallel Petroleum Corporation, and Equity Oil
Company,  assuming  reinvestment  of  dividends  for  each  measurement  period.

PROPOSAL 2:     OTHER MATTERS
--------------------------------------------------------------------------------


At the date of mailing of this proxy statement, we are not aware of any business
to  be  presented  at  the  annual  meeting  other  than  those items previously
discussed.  The  proxy  being  solicited  by  the  board  of  directors provides
authority  for the proxy holder, F. Lynn Blystone, to use his discretion to vote

OUTSIDE AUDITORS

Under new rules promulgated under the Sarbanes-Oxley Act of 2002, shareholders
no longer ratify the selection of our outside auditing firm, which is now
selected by the Audit Committee of the Board of Directors.

ANNUAL REPORT

Our  Annual  Report  on  Form  10-K  for the year ended December 31, 2003, which
contains  our audited financial statements dated December 31, 2003 and 2002, was
mailed  previously  to  shareholders.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING REQUIREMENT

Section 16(a) of the Securities Exchange Act of 1934 and Securities and Exchange
Commission regulations require our directors, certain officers, and greater than
10  percent  shareholders  to file reports of ownership and changes in ownership
with the SEC and to furnish us with copies of all such reports they file.  Based
solely  upon  a  review  of  the copies of the forms furnished to us, or written
representations from certain reporting persons that no reports were required, we
believe  that no person failed to file required reports on a timely basis during
or  in  respect  of  2003.
