ITEM 7.  FINANCIAL STATEMENTS AND EXHIBITS

         (c)      EXHIBITS.

          99.1        Press release dated January 8, 2004 providing certain
                      financial and operating guidance assumptions for 2004.

ITEM 12. RESULTS OF OPERATIONS AND FINANCIAL CONDITION

         On January 8, 2004, Harvest National Resources, Inc. ("Harvest") issued
a Press Release (the "Press Release") providing certain financial and operating
guidance assumptions for 2004, which Press Release also provides certain
estimates relating to Harvest's results of operations and financial condition
for fiscal 2003. The Press Release contains information regarding Harvest's
discretionary cash flow, a non-GAAP financial measure which Harvest's management
believes provides useful information to investors regarding the cash flow from
operations without regard to the changes in the balance sheet asset and
liability accounts. These changes are short term in nature and can fluctuate
based on the activities within a single reporting period. The Press Release
includes a reconciliation of the differences between discretionary cash flow and
net cash provided by operating activities.

         The foregoing is qualified by reference to the Press Release which is
furnished as an exhibit to this report and incorporated herein by reference.


                                   SIGNATURES

         Pursuant to the requirements of the Securities Exchange Act of 1934,
the registrant has duly caused this report to be signed on its behalf by the
undersigned hereunto duly authorized.
