PETROQUEST ENERGY REPLACING EXPIRING SHELF REGISTRATION STATEMENT

LAFAYETTE, LA – April 6, 2009 — PetroQuest Energy, Inc. (NYSE: PQ) announced today that it has filed a universal shelf registration statement on Form S-3 with the Securities and Exchange Commission. The registration statement will replace the Company’s previous registration statement, which will expire on April 11, 2009. As with its previous registration statement, this registration statement, after it has been declared effective by the SEC, will allow the Company to offer and sell, from time to time, up to $200 million in debt securities, shares of common stock, shares of preferred stock, depositary shares, warrants, purchase contracts, units and guarantees of non-convertible debt securities in one or more separate offerings with the size, price and terms to be determined at the time of sale. The terms of any securities offered will be described in a related prospectus supplement to be filed separately with the SEC at the time of the offering.

Charles T. Goodson, Chairman, Chief Executive Officer and President, commented, “PetroQuest has no immediate plans to use the registration statement for any specific financing, but it has been the Company’s practice to have this type of customary shelf registration in place to ensure financing flexibility should the need arise.”

A registration statement relating to these securities has been filed with the Securities and Exchange Commission but has not yet become effective. These securities may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective. This press release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of these securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.
