Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as counsel for Ring Energy, Inc., a Nevada corporation (the “Company”), in connection with the preparation of a Registration Statement on Form S-3 (the “Registration Statement”) filed by Company with the Securities and Exchange Commission (the “Commission”). The Registration Statement relates to the registration under the Securities Act of 1933, as amended (the “Securities Act”), of an indeterminate number of (i) shares of Company common stock, par value $0.001 per share (the “Common Stock”), (ii) shares of Company preferred stock, par value $0.001 per share (the “Preferred Stock”), (iii) debt securities (the “Debt Securities”); (iv) warrants to purchase Common Stock, Preferred Stock or Debt Securities of Company (the “Warrants”), and (v) the units of any of the foregoing (the “Units”), as shall have an aggregate offering price not to exceed $500,000,000. The Common Stock, Preferred Stock, Debt Securities, Warrants and Units are collectively referred to herein as the “Securities.” The Securities registered also include such indeterminate numbers of shares of Common Stock and Preferred Stock as may be issued upon conversion, exchange or exercise of Preferred Stock, Debt Securities and Warrants or pursuant to the anti-dilution provisions of any such Securities.

We also have participated in the preparation of the prospectus (the “Base Prospectus”) contained in the Registration Statement to which this opinion is an exhibit. The Securities will be offered in amounts, at prices and on terms to be determined in light of market conditions at the time of sale and to be set forth in supplements (each, a “Prospectus Supplement”) to the Base Prospectus contained in the Registration Statement, or in a related free writing prospectus. Capitalized terms not defined herein shall have the meanings ascribed to them in the Base Prospectus.

This opinion is furnished pursuant to the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

The opinions rendered are limited to the laws of the State of Nevada and the federal laws of the United States of America. We express no opinion with respect to the laws of any other jurisdiction.

Based upon and subject to the foregoing, and subject to the further assumptions and qualifications set forth below, we are of the opinion that:
