(2)	In no event will the aggregate offering price of all securities issued from time to time pursuant to this registration statement exceed $56,000,000 or the equivalent thereof in foreign currencies, foreign currency units or composite currencies. Such amount represents the offering price of any common stock and preferred stock, the principal amount of any debt securities issued at their stated principal amount, the offering price rather than the principal amount of any debt securities issued at an original issue discount, the offering price of any warrants, the exercise price of any securities issuable upon the exercise of warrants, and the offering price of any securities issued upon settlement of the stock purchase contracts or stock purchase units. The aggregate principal amount of the debt securities may be increased if any debt securities are issued at an original issue discount by an amount such that the offering price to be received by the registrant shall be equal to the above amount to be registered.

No separate consideration will be received for any securities registered hereunder that are issued in exchange for, or upon conversion of, as the case may be, the debt securities, preferred stock or warrants.
(4)	Subject to note (2) above, there is being registered an indeterminate principal amount of debt securities. If any debt securities are issued at an original issue discount, then the offering price of those debt securities shall be in an amount that will result in the aggregate initial price not to exceed $56,000,000, less the dollar amount of any registered securities previously issued. Any offering of debt securities denominated other than in U.S. dollars will be treated as the equivalent of U.S. dollars based on the exchange rate applicable to the purchase of such debt securities at the time of initial offering.
(5)	Subject to note (2) above, there is being registered hereunder an indeterminate number of guarantees issued by one or more subsidiaries of Whiting Petroleum Corporation in connection with the debt securities offered by any prospectus supplement. Pursuant to Rule 457(n) under the Securities Act, no separate filing fee is required for the guarantees.
(6)	Subject to note (2) above, there is being registered an indeterminate number of shares of common stock.
(7)	Subject to note (2) above, there is being registered an indeterminate number of shares of preferred stock.

Whiting Petroleum Corporation
1700 Broadway, Suite 2300
Denver, CO 80290

Ladies and Gentlemen:

     We have acted as counsel for Whiting Petroleum Corporation, a Delaware corporation (the “Company”), in conjunction with the preparation of a Registration Statement on Form S-3 (the “Registration Statement”), including the prospectus constituting a part thereof (the “Prospectus”), to be filed by the Company with the Securities and Exchange Commission (the “SEC”) pursuant to Rule 462(b) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the issuance and sale by the Company from time to time of up to an additional $56,000,000 aggregate amount of: (i) unsecured debt securities of the Company, which may be either senior or subordinated and may include additional 7¹/4% Senior Subordinated Notes due 2012 of the Company (the “Debt Securities”) and which may be fully and unconditionally guaranteed (the “Guarantees”) by certain of the Company’s domestic subsidiaries (the “Subsidiary Guarantors”); (ii) shares of the Company’s common stock, $.001 par value (the “Common Stock”); (iii) shares of the Company’s preferred stock, $.001 par value (the “Preferred Stock”); (iv) warrants to purchase securities of the Company (the “Warrants”); (v) contracts to purchase shares of Common Stock or other securities of the Company (the “Stock Purchase Contracts”); and (vi) units, each comprised of a Stock Purchase Contract and either debt or other securities of the Company or debt obligations of third parties securing the holder’s obligation to purchase securities under the Stock Purchase Contracts (the “Stock Purchase Units” and, together with the Debt Securities, the Guarantees, the Common Stock, the Preferred Stock, the Warrants and the Stock Purchase Contracts, the “Securities”). The Prospectus provides that it will be supplemented by one or more supplements to such Prospectus (each, a “Prospectus Supplement”).

     As counsel to the Company in connection with the proposed issuance and sale of the Securities, we have examined: (i) the Registration Statement, including the Prospectus, and the exhibits (including those incorporated by reference), each constituting a part of the Registration Statement; (ii) the Company’s Amended and Restated Certificate of Incorporation and By-laws, each as amended to date; (iii) the Indenture, dated May 11, 2004, among the Company, the Guarantors listed therein and J.P. Morgan Trust Company, National Association, as trustee (the “2004 Indenture”); (iv) the Subordinated Indenture, dated April 19, 2005, among the Company, the Guarantors listed therein and J.P. Morgan Trust Company, National Association, as trustee (the “Subordinated Indenture”); (v) the form of indenture for senior Debt Securities included as an exhibit to the Registration Statement (the “Senior Indenture” and, together with the 2004 Indenture and the Subordinated Indenture, the “Indentures”); and (vii) such other proceedings, documents and records as we have deemed necessary to enable us to render this opinion.

     In our examination of the above-referenced documents, we have assumed the genuineness of all signatures, the authenticity of all documents, certificates and instruments submitted to us as originals and the conformity with the originals of all documents submitted to us as copies. We have also assumed that (i) the Registration Statement, and any amendments thereto, will have become effective and will comply with all applicable laws; (ii) a Prospectus Supplement, if required, will have been prepared and filed with the SEC describing the Securities offered thereby; (iii) all Securities will be issued and sold in compliance with applicable federal and state securities laws and in the manner stated in the Registration Statement and any applicable Prospectus Supplement; (iv) the Senior Indenture and the Subordinated Indenture, together with any supplemental indenture relating to a series of Debt Securities to be issued under any of the Indentures, will each be duly authorized, executed and delivered by the parties thereto in substantially the form reviewed by us; (v) a definitive purchase, underwriting or similar agreement with respect to any Securities offered will have been duly authorized and validly executed and delivered by the Company and the other parties thereto; (vi) any Securities issuable upon conversion, exchange or exercise of any Security being offered will have been duly authorized, created and, if appropriate, reserved for issuance upon such conversion, exchange or exercise; and (vii) with respect to shares of Common Stock or Preferred Stock offered, there will be sufficient shares of Common Stock or Preferred Stock authorized under the Company’s Amended and Restated Certificate of Incorporation and not otherwise reserved for issuance.

     Based upon the foregoing, we are of the opinion that:

     2. All requisite action necessary to make any Debt Securities and any Guarantees valid, legal and binding obligations of the Company and the Subsidiary Guarantors, respectively, subject to (i) bankruptcy, insolvency, reorganization, fraudulent transfer, fraudulent conveyance, moratorium and other similar laws of general application affecting the rights and remedies of creditors and (ii) general principles of equity, regardless of whether applied in a proceeding in equity or at law, shall have been taken when:

The Board of Directors of each Subsidiary Guarantor, or a committee thereof or one or more officers of such Subsidiary Guarantor, in each case duly authorized by the Board of Directors, shall have taken action to establish the terms of the Guarantees and to authorize the issuance and sale of such Guarantees;

     c. The terms of such Debt Securities and, if applicable, Guarantees and of their issuance and sale have been established in conformity with the applicable Indenture so as not to violate any applicable law or result in a default under or breach of any agreement or instrument binding upon the Company or any Subsidiary Guarantor and so as to comply with any requirements or restrictions imposed by any court or governmental entity having jurisdiction over the Company or a Subsidiary Guarantor;
