Ladies and Gentlemen:

We were previously principal accountants for TransAtlantic Petroleum Ltd. and, under the date of March 23, 2012, we reported on the consolidated balance sheets of TransAtlantic Petroleum Ltd. as of and for the years ended December 31, 2011 and 2010 and the related consolidated statements of operations and comprehensive loss, equity and cash flows for each of the years in the three-year period ended December 31, 2011, and the effectiveness of internal control over financial reporting as of December 31, 2011.

On February 21, 2012, we were notified that TransAtlantic Petroleum Ltd. engaged KPMG, LLP, a Delaware limited liability partnership (“KPMG USA”), as its principal accountant for the year ending December 31, 2012 and that the auditor-client relationship with KPMG LLP, a Canadian limited liability partnership (“KPMG Canada”), would cease upon completion of the audit of TransAtlantic Petroleum Ltd.’s consolidated financial statements as of and for the year ended December 31, 2011, and the effectiveness of internal control over financial reporting as of December 31, 2011, and the issuance of our reports thereon.

On March 23, 2012, we completed our audit and the auditor-client relationship ceased. We have read TransAtlantic Petroleum Ltd.’s statements included under Item 4.01 of its Amendment No. 1 to Current Report on Form 8-K/A dated February 21, 2012, and we agree with such statements.

Very truly yours,

(Signed)
