    This Amendment No. 1 to Schedule 13D (this "Amendment") is being filed 
by Cadell S. Liedtke, Michael J. Grella and Henry G. Musselman (collectively, 
the "Reporting Persons") to reflect a change in the percentage ownership of 
each of the Reporting Persons of the Common Stock, $0.10 par value (the 
"Common Stock"), of Costilla Energy, Inc. (the "Company") from such 
percentage ownership reflected in the Schedule 13D filed by the Reporting 
Persons on October 18, 1996 (the "Original 13D").  On November 6, 1996, the 
Company issued 475,000 shares of Common Stock pursuant to the exercise of a 
portion of the underwriters' over-allotment option in connection with the 
Company's initial public offering.  Due to the increased number of shares of 
Common Stock outstanding as a result of that issuance, the percentage 
ownership of each of the Reporting Persons decreased since the number of 
shares of Common Stock owned by the Reporting Persons has not changed from 
the information provided in the Original 13D.

    As a result, the Original 13D is hereby amended to change the percentage 
ownership of each of the Reporting Persons as reported in the Original 13D to 
the following:

                   Cadell S. Liedtke        21.9%
                   Michael J. Grella        12.9%
                   Henry G. Musselman        5.8%

    Except as expressly amended and modified by this Amendment, the Original 
13D remains unchanged and in full force and effect.
