                      Re: Comment Letter Received May 12, 2006
                          CREDO Petroleum Corporation
                          Form 10-K, Filed January 30, 2006
                          File No. 000-08877

On May 17, 2006 I spoke with Mark Wojciechowski with the
Securities and Exchange Commission Division of Corporation
Finance and requested an extension of time for CREDO Petroleum
Corporation's response to the comment letter identified above
from May 22, 2006 to June 20, 2005.  The company is requesting
this extension of time for the following reasons:

          1.  Due to previous commitments, key company personnel
              responsible for responding to the SEC's comment letter
              will be out of the country and unavailable until
              May 30, 2006;
          2.  To allow the Company the required time to prepare for its
              second fiscal quarter quarterly review and to complete
              and file its Quarterly Report on Form 10-Q; and
          3.  To allow the Company adequate time to thoroughly
              understand and address the comments presented in the
              comment letter.

     Please contact me directly with any questions or concerns
at 303-297-2200.

                              Sincerely,

                              CREDO PETROLEUM CORPORATION
