POWER OF ATTORNEY
                         FOR EXECUTING FORMS 3, 4 AND 5

I appoint William C. Liedtke as my attorney-in-fact to:

         (1)      execute and file with the Securities and Exchange Commission
                  on my behalf Forms 3, 4 or 5 as required by Section 16(a) of
                  the Securities Exchange Act of 1934 and the rules thereunder,
                  and any amendments thereto; and

         (2)      do anything in connection with the foregoing which such
                  attorney-in-fact may deem legally required by me or in my best
                  interest.

I grant to such attorney-in-fact full power and authority to do and perform any
and every act and thing whatsoever requisite, necessary or proper to be done in
the exercise of any of the rights and powers herein granted, as fully to all
intents and purposes as I could do if personally present, with full power of
substitution, hereby ratifying and confirming all that such attorney-in-fact
shall lawfully do or cause to be done by virtue of this Power of Attorney and
the rights and powers herein granted.

I acknowledge that this Power of Attorney is granted by me individually.

I acknowledge that the foregoing attorney-in-fact, in serving in such capacity
at my request, is not assuming, nor is Castle Energy Corporation assuming, any
of my responsibilities to comply with Section 16 of the Securities Exchange Act
of 1934.

This Power of Attorney supersedes any Power of Attorney executed by me, which is
hereby revoked. This Power of Attorney shall remain in effect until I am no
longer required to file Forms 3, 4, and 5 with respect to my holdings of and
transactions in securities issued by Castle Energy Corporation, unless earlier
revoked in writing by me.

This Power of Attorney is executed on December 27, 2004.

Signed:         /S/ SIDNEY F. WENTZ
