Form 10-K for Fiscal Year Ended December 31, 2013

Filed March 5, 2014

File No. 001-32681

Response Letter dated February 3, 2015

Dear Messrs. Hiller and Winfrey:

This letter is in response to your letter dated February 13, 2015 (the “Comment Letter”), to PetroQuest Energy, Inc. (the “Company”), transmitting the comments of the staff (the “Staff”) of the Division of Corporate Finance of the U.S. Securities and Exchange Commission (the “Commission”) relating to the above referenced Form 10-K for the fiscal year ended December 31, 2013 (the “Form 10-K”). For your convenience, each response of the Company is set forth in ordinary type beneath the corresponding comment of the Staff from the Comment Letter appearing in bold type. For ease of reference, the heading and numbered paragraphs below correspond to the headings and numbered comments in the Comment Letter.

We hope the Staff will consider this letter to be responsive to the comments. We respectfully request an opportunity to discuss this letter further with the Staff if, following a review of this information, the Staff does not concur with our analysis.

Form 10-K for Fiscal Year Ended December 31, 2013

Oil and Gas Reserves, page 7

1. Your response to comment number 1 from our letter dated January 30, 2015 includes discussion of adjustments that might have been made to your reported PUD volumes as of December 31, 2013 had your revised review process been in place at that time. This discussion suggests that you have concluded that you had established reasonable certainty for all other previously disclosed PUD volumes. However, in view of the factors described in our comment, and given the revisions you have determined are necessary to your review process, such a conclusion does not appear supportable.

Accordingly, provide an analysis that addresses the impact of removing all previously disclosed PUD volumes for which you had not established reasonable certainty, or explain to us why you believe no other revisions are necessary. In particular, explain how you have established that the three oldest PUD “layers” as of December 31, 2012 and the four oldest PUD “layers” as of December 31, 2013 were reasonably certain as of those dates.

COMPANY RESPONSE: In response to the Staff’s comment, we have reviewed the reasonable certainty of our PUD reserves as of December 31, 2012 and December 31, 2013, including, specifically, the three oldest PUD “layers” as of December 31, 2012 and the four oldest PUD “layers” as of December 31, 2013. This extensive review was performed by our PUD Review Committee on a PUD-by-PUD basis utilizing the enhanced reserve booking process disclosed in our prior response letter dated February 3, 2015, as supplemented by our discussion with the Staff on February 20, 2015 to focus on the reasonable certainty of the oldest PUD “layers” of our PUD reserves. Based on that discussion, we believe we have a better understanding of what constitutes a final investment decision, which is necessary for the adoption of a development plan and the booking of PUD reserves in compliance with Rule 4-10(a) of Regulation S-X, and will utilize our enhanced reserve booking procedures in connection with our future filings with the Commission.

In connection with the Company’s response to the Staff, the Company acknowledges that (i) the Company is responsible for the adequacy and accuracy of the disclosure in the filing; (ii) Staff comments or changes to disclosure in response to Staff comments do not foreclose the Commission from taking any action with respect to the filing; and (iii) the Company may not assert Staff comments as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.

Please call the undersigned at (337) 232-7028 with any additional comments or questions you may have.

Pursuant to the Staff’s request in our discussion on February 20, 2015, we have revised the tables below that were previously included in Appendix 1 from our January 22, 2015 response letter to further clarify the ultimate disposition status of those PUDs identified as “Written off - other (primarily SEC pricing; also new opportunities and other)”. We advise the Staff that while the title of the disposition status included the term “SEC pricing”, “SEC pricing” was primarily applicable to reserves at December 31, 2011 and 2012. This table also illustrates the impact of our significant acquisition in 2013 on our PUDs as of December 31, 2012.

Reserves at 12/31/12 scheduled to be drilled in 2013:
