                                  CERTIFICATIONS


     I, Leo William Kerrigan, certify that:

1.   I have reviewed this Form 10-KSB of Petrogen Corporation;

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.   The  registrant's  other  certifying  officer(s)  and  I  are   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 small
          business issuer'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.   The  registrant's  other  certifying   officer(s)  and   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.
