Exhibit 23.6

Consent of DeGolyer and MacNaughton

April 7, 2005

Cimarex Energy Co.
1700 Lincoln Street, Suite 1800
Denver, Colorado
80203-4518

Gentlemen:

        In connection with the Amendment No. 1 to Registration Statement on Form S-4 of Cimarex Energy Co. to be filed with the Securities and Exchange Commission on or about April 7, 2005, we hereby consent to the references to our firm in the said Registration Statement found under the headings "Risks Relating to the Combined Company's Business Following the Merger" and "Experts." We further consent to the references to the estimates of reserves and revenue that were taken from our "Appraisal Report as of December 31, 2004 on Certain Properties owned by Magnum Hunter Production, Inc. SEC Case," "Appraisal Report as of December 31, 2003 on Certain Properties owned by Magnum Hunter Production, Inc. SEC Case," and "Appraisal Report as of December 31, 2002 on Certain Properties owned by Magnum Hunter Production, Inc. SEC Case" (our Reports). However, since the oil, condensate, natural gas liquids, and natural gas reserves and revenue estimates set forth in our Reports have been combined with reserves and revenue estimates of other petroleum consultants, we are necessarily unable to verify the accuracy of the reserves and revenue values contained in the Registration Statement.

Very truly yours,

/s/ DeGolyer and MacNaughton
