EXHIBIT 31.1

                                  CERTIFICATION

     I, Calvin Wallen III, Chief Executive  Officer and Chief Financial  Officer
of Cubic Energy, Inc., certify that:

1.   I have reviewed this Form 10-KSB of Cubic Energy, Inc. (the "Registrant");

2.   Based on my knowledge, this report does not contain any untrue statement of
     a material  fact or omit to state a  material  fact  necessary  to make the
     statements made, in light of the circumstances  under which such statements
     were made,  not  misleading  with  respect  to the  period  covered by this
     report;

3.   Based on my  knowledge,  the  financial  statements,  and  other  financial
     information  included  in  this  report,  fairly  present  in all  material
     respects the financial  condition,  results of operations and cash flows of
     the Registrant as of, and for, the periods presented in this report;

4.   I am responsible for establishing and maintaining  disclosure  controls and
     procedures  (as defined in Exchange Act Rules  13a-15(e) and 15d-15(e)) for
     the Registrant and have:

          (a) Designed such disclosure  controls and procedures,  or caused such
          disclosure   controls  and   procedures  to  be  designed   under  our
          supervision,  to ensure  that  material  information  relating  to the
          Registrant,  including its consolidated subsidiaries, is made known to
          us by others within those entities,  particularly during the period in
          which this report is being prepared;

          (b)  Evaluated  the  effectiveness  of  the  Registrant's   disclosure
          controls and procedures  and presented in this report our  conclusions
          about the effectiveness of the disclosure controls and procedures,  as
          of the  end of the  period  covered  by  this  report  based  on  such
          evaluation; and

          (c) Disclosed in this report any change in the  Registrant's  internal
          control over financial reporting that occurred during the Registrant's
          most recent fiscal quarter (the Registrant's  fourth fiscal quarter in
          the case of an annual  report)  that has  materially  affected,  or is
          reasonably  likely to materially  affect,  the  Registrant's  internal
          control over financial reporting; and

5.   I have disclosed,  based on our most recent  evaluation of internal control
     over  financial  reporting,  to the  Registrant's  auditors  and the  audit
     committee of the Registrant's board of directors (or persons performing the
     equivalent functions):

          (a) All significant deficiencies and material weaknesses in the design
          or operation of internal  control over financial  reporting  which are
          reasonably  likely to  adversely  affect the  Registrant's  ability to
          record, process, summarize and report financial information; and

          (b) Any fraud,  whether or not material,  that involves  management or
          other  employees  who  have a  significant  role  in the  Registrant's
          internal control over financial reporting.
