Exhibit 99.1

STONE ENERGY CORPORATION

Announces Private Offering of $250 Million of Convertible Notes

LAFAYETTE, LA. February 28, 2012

Stone Energy Corporation (NYSE: SGY) (the “Company”) today announced that it intends, subject to market and other conditions, to offer $250 million aggregate principal amount of Convertible Notes due 2017 (the “Convertible Notes”) in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The Company expects to grant an over-allotment option to the initial purchasers for up to an additional $25 million aggregate principal amount of Convertible Notes. The Convertible Notes are expected to pay interest semiannually and will be convertible into cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election, based on a conversion rate to be determined. The Convertible Notes will mature in 2017, unless repurchased or converted in accordance with their terms prior to such date. Prior to December 1, 2016, the Convertible Notes will be convertible only upon the occurrence of certain events and during certain periods, and thereafter, at any time until the second scheduled trading day immediately preceding the maturity date.

In connection with the offering, the Company expects to enter into convertible note hedge transactions in respect of its common stock with one or more affiliates of the initial purchasers of the Convertible Notes (the “Option Counterparties”). These convertible note hedge transactions are expected to reduce the potential dilution upon future conversion of the Convertible Notes. In addition, the Company expects to enter into separate warrant transactions with the Option Counterparties at a higher strike price. The warrant transactions could separately have a dilutive effect to the extent that the market value per share of the Company’s common stock exceeds the applicable strike price of the warrants. If the initial purchasers exercise their over-allotment option, the Company expects to enter into additional convertible note hedge and warrant transactions with Option Counterparties.

The Company intends to apply a portion of the net proceeds from the sale of the Convertible Notes and the proceeds from the warrant transactions to fund the cost of the convertible note hedge transactions entered into between the Company and the Option Counterparties. The Company expects to apply the remaining net proceeds for general corporate purposes, which may include providing longer term financing for the recently closed Pompano, Wideberth and Appalachian acquisitions and the repayment of outstanding borrowings under the Company’s bank credit facility.

The Company has been advised that, in connection with establishing their initial hedge of the convertible note hedge and warrant transactions, the Option Counterparties and/or their affiliates expect to enter into various cash-settled over-the-counter derivative transactions with respect to shares of the Company’s common stock concurrently with, or shortly after, the pricing of the Convertible Notes. This activity could have the effect of increasing or preventing a decline in the price of the Company’s common stock or the Convertible Notes at that time. In addition, the Option Counterparties and/or their affiliates may modify their hedge positions by unwinding these derivative transactions, entering into or unwinding additional cash-settled over-the-counter derivative transactions with respect to the Company’s common stock and/or purchasing or selling shares of the Company’s common stock or other of the Company’s securities in secondary market transactions from time to time following the pricing of the Convertible Notes and prior to the maturity of the Convertible Notes (and are likely to do so during any conversion period related to a conversion of Convertible Notes).

This press release is neither an offer to sell nor a solicitation of an offer to buy the Convertible Notes or the shares of common stock issuable upon conversion of the Convertible Notes, nor shall there be any sale of these securities in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such state or jurisdiction.

The Convertible Notes and the common stock issuable upon conversion of the Convertible Notes have not been registered under the Securities Act, or the securities laws of any other jurisdiction, and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements. The offering is being made to qualified institutional buyers pursuant to Rule 144A under the Securities Act.
