Dear Mr. Schwall:

TransAtlantic Petroleum Corp. (“TransAtlantic”) hereby submits the following responses to the letter dated September 21, 2009 containing comments from the staff (the “Staff”) of the Securities and Exchange Commission (the “Commission”) relating to TransAtlantic’s Form 10-K for the fiscal year ended December 31, 2008 filed April 1, 2009, Form 10-Q for the fiscal quarter ended March 31, 2009 filed May 27, 2009 (the “First Quarter Form 10-Q”) and Form 10-Q for the fiscal quarter ended June 30, 2009 filed August 14, 2009 (the “Second Quarter Form 10-Q”).

For your convenience, we have restated the Staff’s comments below, together with our response to each respective comment. For your convenience, we are also sending to each of Gary Newberry, Shannon Buskirk, Chris White, Ronald Winfrey and Doug Brown a copy of this letter and copies of the Form 10-Q amendments discussed in the responses below marked to show changes from the versions filed previously. We respectfully request that the Staff provide any further comments at its earliest convenience.

TransAtlantic hereby acknowledges that:

• TransAtlantic is responsible for the adequacy and accuracy of the disclosure in the filing;

• The Staff’s comments or changes to disclosure in response to the Staff’s comments do not foreclose the Commission from taking any action with respect to the filing; and

• TransAtlantic may not assert the Staff’s comments as a defense in any proceedings initiated by the Commission or any person under the federal securities laws of the United States.

Form 10-K for the Fiscal Year Ended December 31, 2008

Notes to Consolidated Financial Statements

Note 14 – Acquisitions, Page F-25

1. We have reviewed your response to prior comment five noting you allocated the cost of the acquisition of Longe to its assets and liabilities acquired using the carrying value as of the date of acquisition. Paragraph 7 of SFAS 141 states the cost of an acquisition should be allocated using the fair value of those assets and liabilities acquired. Please tell us and identify the differences that may result in the values assigned to the assets and liabilities acquired from Longe if the fair value of those assets and liabilities had been used to allocate the cost of the acquisition.

Response:

To clarify our response to prior comment five, the fair value of Longe’s assets and liabilities acquired was used to allocate the cost of the acquisition (i.e., the fair value of the consideration paid) prior to allocating the reduction of the excess of the fair value to the individual tangible assets. Therefore, there is no difference in the resulting values assigned to the assets and liabilities.

TransAtlantic allocated the fair value of the consideration paid in the following order:

(i) first to the fair value of the financial assets and liabilities acquired (consisting of deposits on equipment and accounts payable). Each of these assets and liabilities was short-term in nature and was settled at the carrying value within 60 days of closing. Due to their short-term to maturity and or highly liquid nature, TransAtlantic determined that the carrying value of these assets and liabilities equaled their fair value as of the date of acquisition;

(ii) second to the fair value of the current assets acquired (consisting of other prepaid assets). Each of these assets was short-term in nature and was settled at their carrying value within 60 days of closing. Due to their short-term nature, TransAtlantic determined that the carrying value of these assets equaled their fair value as of the date of acquisition; and

(iii) finally to the fair value of the property and equipment acquired. However, the sum of the fair value of the individual tangible assets (i.e., property and equipment) (approximately $45.66 million) exceeded the remaining fair value of consideration paid (approximately $32.35 million). In accordance with Paragraph 44 of SFAS 141, this excess (approximately $13.31 million) was allocated as a pro rata reduction in the fair value of the individual tangible assets (i.e., property and equipment) and no portion of the pro rata reduction was allocated to financial assets or other current assets.

As such, there is no difference in the resulting values because TransAtlantic allocated the fair value of the consideration paid to the fair value of individual assets and liabilities acquired prior to allocating the reduction of the excess of the fair value to the individual tangible assets.
