RE:   Election to extend term of Partnerships for additional two years


      As previously  described to you, the limited  partnership  agreements,  as
amended  (the  "Agreements")  for the above  referenced  Geodyne  Energy  Income
Limited  Partnerships  (the  "Partnerships")  provide that the Partnerships will
automatically terminate and dissolve on December 31, 2003.

The Agreements give Geodyne Resources as General Partner an option to extend the
terms of the Partnerships  for up to five additional two year terms.  Four years
ago Geodyne exercised the first such extensions, and two years ago exercised the
second such  extensions.  Geodyne is hereby notifying you that it has elected to
extend  the  Partnerships'  terms  for a  third,  additional  two  year  period.
Accordingly,  Geodyne will file amendments to the Partnerships'  Certificates of
Limited Partnership extending the Partnerships' terms until December 31, 2005.

If you  have any  questions  concerning  the  Partnerships'  extensions,  please
contact Geodyne Investor Services at 918-583-1791 or 888-436-3963.

                                    Very truly yours,
