Ladies and Gentlemen:

We have acted as counsel to Transmeridian Exploration Inc., a company organized under the laws of the British Virgin Islands (the “Company”), in connection with the registration, pursuant to a registration statement on Form S-4, as amended by Pre-Effective Amendment No. 1 thereto (the “Registration Statement”), filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Act”), of (i) the proposed offer by the Company to exchange (the “Exchange Offer”) all outstanding unregistered Senior Secured Notes due 2010 of the Company (the “Outstanding Notes”) for Senior Secured Notes due 2010 of the Company (the “Registered Notes”) which have been registered under the Act, and (ii) the guarantees (the “Guarantees”) of the entities listed in the Registration Statement (the “Guarantors”). The Outstanding Notes have been, and the Registered Notes will be, issued pursuant to an Indenture, dated as of December 12, 2005 (as supplemented by that certain First Supplemental Indenture, dated as of December 22, 2005, and that certain Second Supplemental Indenture, dated as of May 24, 2006, the “Indenture”), by and among the Company, the Guarantors and The Bank of New York, as trustee (the “Trustee”).

We have examined originals or certified copies of such corporate records of the Company and the Guarantors and other certificates and documents of officials of the Company and the Guarantors, public officials and others as we have deemed appropriate for purposes of this letter. We have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity to authentic original documents of all copies submitted to us as conformed and certified or reproduced copies. We have also assumed the legal capacity of natural persons, the corporate or other power of all persons signing on behalf of the parties to all documents other than the Company and the Guarantors, the due authorization, execution and delivery of all documents by the parties thereto other than the Company and the Guarantors, that the Registered Notes will conform to the specimens examined by us and that the Trustee’s certificate of authentication of Registered Notes will be manually signed by one of the Trustee’s authorized officers.

Based upon the foregoing and subject to the assumptions, exceptions, qualifications and limitations set forth hereinafter, we are of the opinion that, when (a) the Registration Statement has become effective under the Act, (b) the Outstanding Notes have been exchanged in the manner described in the prospectus forming a part of the Registration Statement, (c) the Registered Notes have been duly executed, authenticated, issued and delivered in accordance with the terms of the Indenture against receipt of the Outstanding Notes surrendered in exchange therefor, (d) the Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended, and (e) applicable provisions of “blue sky” laws have been complied with,
