Gentlemen:

We hereby consent to the incorporation in the Registration Statement on Form
S-1 and the Registration Statement on Form S-4 of Abraxas Petroleum
Corporation for the year ended December 31, 2002, of the references to
DeGolyer and MacNaughton in the "Business -- Reserves Information" and
"Experts" sections and to the use by reference of information contained in
our "Appraisal Report as of December 31, 2002 on Certain Properties owned by
Abraxas Petroleum Corporation," "Appraisal Report as of December 31, 2001 on
Certain Interests Owned by Abraxas Petroleum Corporation," and "Appraisal
Report as of December 31, 2002 on Certain Interests owned by Grey Wolf
Exploration Inc. in Canada (Canadian Dollars)" (our Reports). However, since
the petroleum reserves estimates set forth in our Reports have been combined
with reserves estimates of other petroleum consultants, we are necessarily
unable to verify the accuracy of the estimates of reserves and values
contained in the aforementioned Registration Statements.



                                       Very truly yours,


                                       /s/ DEGOLYER AND MACNAUGHTON
                                           DeGOLYER and MacNaughton
