STONE ENERGY CORPORATION

Announces Temporary Suspension of Drilling Operations and Intention to Drill Deeper at Lighthouse Bayou Prospect

LAFAYETTE, LA. December 8, 2011

Stone Energy Corporation (NYSE: SGY) today announced that the partnership drilling the Lighthouse Bayou prospect in southwestern Louisiana has decided to temporarily suspend drilling operations. The well has reached a total depth of 25,500 feet and, in doing so, has reached the technical limits of the current drilling equipment. Current plans include running protective liner to the current depth, temporarily plugging and abandoning the well, procuring drilling equipment with higher pressure ratings, and returning to drill deeper in 2012 to test the objective Wilcox section.

Stone has an approximately 25% working interest in the prospect. The prospect is Stone’s third exploration well in the Deep Gas play of southwestern Louisiana. The first two prospects, LaPosada and South Erath were discoveries, with initial production expected to occur in the next few months and offset development wells planned in 2012 and 2013, respectively.

Stone Energy is an independent oil and natural gas company headquartered in Lafayette, Louisiana, and is engaged in the acquisition, exploration, exploitation, development and operation of oil and gas properties located primarily in the Gulf of Mexico. Stone is also active in the Appalachia region. For additional information, contact Kenneth H. Beer, Chief Financial Officer, at
